High Speed CAN-Transceiver wih Bus Wake-up Overview Descripion The TLE7251V is a ransceiver designed for HS CAN neworks in auomoive and indusrial applicaions. As an inerface beween he physical bus layer and he CAN proocol conroller, he TLE7251V drives he signals o he bus and proecs he microconroller agains inerferences generaed wihin he nework. Based on he high symmery of he CANH and CANL signals, he TLE7251V provides a very low level of elecromagneic emission (EME) wihin a wide frequency range. The TLE7251V is available in a small, leadless PG-TSON-8 package and in a PG-DSO-8 package. Boh packages are RoHS complian and halogen free. Addiionally he PG-TSON-8 package suppors he solder join requiremens for auomaed opical inspecion (AOI). The TLE7251VLE and he TLE7251VSJ are fulfilling or exceeding he requiremens of he ISO11898-2. The TLE7251V provides a digial supply inpu V IO and a sand-by mode. I is designed o fulfill he enhanced physical layer requiremens for CAN FD and suppors daa raes up o 2 MBi/s. On he basis of a very low leakage curren on he HS CAN bus inerface he TLE7251V provides an excellen passive behavior in power-down sae. These and oher feaures make he TLE7251V excepionally suiable for mixed supply HS CAN neworks. Based on he Infineon Smar Power Technology SPT, he TLE7251V provides excellen ESD immuniy ogeher wih a very high elecromagneic immuniy (EMI). The TLE7251V and he Infineon SPT echnology are AEC qualified and ailored o wihsand he harsh condiions of he auomoive environmen. Two differen operaing modes, addiional fail-safe feaures like a TxD ime-ou and he opimized oupu slew raes on he CANH and CANL signals make he TLE7251V he ideal choice for large HS CAN neworks wih high daa ransmission raes.

High Speed CAN-Transceiver wih Bus Wake-up Funcional descripion 4 Funcional descripion HS CAN is a serial bus sysem ha connecs microconrollers, sensors and acuaors for real-ime conrol applicaions. The use of he Conroller Area Nework (abbreviaed CAN) wihin road vehicles is described by he inernaional sandard ISO 11898. According o he 7-layer OSI reference model he physical layer of a HS CAN bus sysem specifies he daa ransmission from one CAN node o all oher available CAN nodes wihin he nework. The physical layer specificaion of a CAN bus sysem includes all elecrical and mechanical specificaions of a CAN nework. The CAN ransceiver is par of he physical layer specificaion. Several differen physical layer sandards of CAN neworks have been developed in recen years. The TLE7251V is a high speed CAN ransceiver wih a dedicaed bus wake-up funcion and defined by he inernaional sandard ISO 11898-5. 4.1 High speed CAN physical layer TxD CANH CANL VIO VCC VIO = Digial supply volage VCC = Transmier supply volage TxD = Transmi daa inpu from he microconroller RxD = Receive daa oupu o he microconroller CANH = Bus level on he CANH inpu/oupu CANL = Bus level on he CANL inpu/oupu VDiff = Differenial volage beween CANH and CANL VDiff = VCANH VCANL VDiff VCC dominan receiver hreshold recessive receiver hreshold RxD VIO Loop(H,L) Loop(L,H) Figure 3 High speed CAN bus signals and logic signals Daa Shee 7 Rev. 1.01

High Speed CAN-Transceiver wih Bus Wake-up Funcional descripion The TLE7251V is a high speed CAN ransceiver, operaing as an inerface beween he CAN conroller and he physical bus medium. A HS CAN nework is a wo wire, differenial nework which allows daa ransmission raes for CAN FD frames up o 2 MBi/s. Characerisic for HS CAN neworks are he wo signal saes on he HS CAN bus: dominan and recessive (see Figure 3). V CC, V IO and GND are he supply pins for he TLE7251V. The pins CANH and CANL are he inerface o he HS CAN bus and operae in boh direcions, as an inpu and as an oupu. RxD and TxD pins are he inerface o he CAN conroller, he TxD pin is an inpu pin and he RxD pin is an oupu pin. The STB pin is he inpu pin for he mode selecion (see Figure 4). By seing he TxD inpu pin o logical low he ransmier of he TLE7251V drives a dominan signal o he CANH and CANL pins. Seing TxD inpu o logical high urns off he ransmier and he oupu volage on CANH and CANL discharges owards he recessive level. The recessive oupu volage is provided by he bus biasing (see Figure 1). The oupu of he ransmier is considered o be dominan, when he volage difference beween CANH and CANL is a leas higher han 1.5 V (V Diff = V CANH - V CANL ). Parallel o he ransmier he normal-mode receiver moniors he signal on he CANH and CANL pins and indicaes i on he RxD oupu pin. A dominan signal on he CANH and CANL pins ses he RxD oupu pin o logical low, vice versa a recessive signal ses he RxD oupu o logical high. The normal-mode receiver considers a volage difference (V Diff ) beween CANH and CANL above 0.9 V as dominan and below 0.5 V as recessive. To be conform wih HS CAN feaures, like he bi o bi arbiraion, he signal on he RxD oupu has o follow he signal on he TxD inpu wihin a defined loop delay Loop 255 ns. The hresholds of he digial inpus (TxD and STB) and also he RxD oupu volage are adaped o he digial power supply V IO. Daa Shee 8 Rev. 1.01

High Speed CAN-Transceiver wih Bus Wake-up Funcional descripion 4.2 Modes of operaion The TLE7251V suppors wo differen modes of operaion, sand-by mode and normal-operaing mode while he ransceiver is supplied according o he specified funcional range. The mode of operaion is seleced by he STB inpu pin (see Figure 4). V CC = don care V IO > V IO(UV,R) sand-by mode STB = 1 STB = 0 STB = 1 V CC > V CC(UV,R) V IO > V IO(UV,R) normal-operaing mode STB = 0 Figure 4 Mode sae diagram 4.2.1 Normal-operaing mode In normal-operaing mode he ransmier and he receiver of he HS CAN ransceiver TLE7251V are acive (see Figure 1). The HS CAN ransceiver sends he serial daa sream on he TxD inpu pin o he CAN bus. The daa on he CAN bus is displayed a he RxD pin simulaneously. A logical low signal on he STB pin selecs he normal-operaing mode, while he ransceiver is supplied by V CC and V IO (see Table 2 for deails). 4.2.2 Sand-by mode The sand-by mode is an idle mode of he TLE7251V wih opimized power consumpion. In sand-by mode he ransmier and he normal-mode receiver are urned off. The TLE7251V can no send any daa o he CAN bus nor receive any daa from he CAN bus. The low-power receiver is conneced o he bus lines. Wake-up signals are indicaed on he RxD oupu pin. An addiional filer, implemened inside he low-power receiver, ensures ha only dominan and recessive signals on he CAN bus, which are longer han he CAN aciviy filer ime Filer, are indicaed a he RxD oupu pin (see Figure 8). A logical high signal on he STB pin selecs he sand-by mode, while he ransceiver is supplied by he digial supply V IO (see Table 2 for deails). In sand-by mode he bus inpu pins are biased o GND via he receiver inpu resisors R i. The undervolage deecion on he ransmier supply V CC is urned off, allowing o swich off he V CC supply in sand-by mode. Daa Shee 9 Rev. 1.01

Turning off he digial power supply V IO, he ransceiver powers down and remains in he power-down sae. While swiching off he ransmier supply V CC, he ransceiver eiher changes o he forced sand-by mode, or remains in sand-by mode (deails see Figure 5).

High Speed CAN-Transceiver wih Bus Wake-up Funcional descripion 4.3.1 Power-down sae Independen of he ransmier supply V CC and of he STB inpu pin, he TLE7251V is in power-down sae when he digial supply volage V IO is urned off (see Figure 5). In he power-down sae he inpu resisors of he receiver are disconneced from he bus biasing V CC /2. The CANH and CANL bus inerface of he TLE7251V is floaing and acs as a high-impedance inpu wih a very small leakage curren. The high-ohmic inpu does no influence he recessive level of he CAN nework and allows an opimized EME performance of he enire HS CAN nework (see also Table 2). 4.3.2 Forced sand-by mode The forced sand-by mode is a fail-safe mode o avoid any disurbance on he HS CAN bus, while he TLE7251V faces a loss of he ransmier supply V CC. In forced sand-by mode, he ransmier and he normal-mode receiver are urned off and herefore he ransceiver TLE7251V can no disurb he bus media. Similar o he sand-by mode, he low-power receiver is conneced o he bus lines and wake-up signals on he CAN bus are indicaed a he RxD oupu pin (see Figure 8). In forced sand-by mode he bus is also biased o GND (deails see Table 2) via he receiver inpu resisors. The forced sand-by mode can only be enered when he ransmier supply V CC is no available, eiher by powering up he digial supply V IO only or by urning off he ransmier supply in normal-operaing mode. While he ransceiver TLE7251V is in forced sand-by mode, swiching he STB inpu pin o logical high riggers a mode change o sand-by mode (see Figure 5). 4.3.3 Power-up The HS CAN ransceiver TLE7251V powers up if a leas he digial supply V IO is conneced o he device. By defaul he device powers up in sand-by mode, due o he inernal pull-up resisor on he STB pin o V IO. In case he device needs o power-up o normal-operaing mode, he STB pin needs o be pulled acive o logical low and he supplies V IO and V CC have o be conneced. By supplying only he digial power supply V IO he TLE7251V powers up eiher in forced sand-by mode or sand-by mode, depending on he signal of he STB inpu pin. (see Figure 5). Daa Shee 11 Rev. 1.01

The undervolage deecion on he digial supply V IO has he highes prioriy. I is independen of he ransmier supply V CC and also independen of he currenly seleced operaing mode.

High Speed CAN-Transceiver wih Bus Wake-up Funcional descripion 4.3.5 Undervolage on he ransmier supply V CC In case he ransmier supply V CC falls below he hreshold V CC < V CC(UV,F), he ransceiver TLE7251V changes he mode of operaion o forced sand-by mode. The ransmier and also he normal-mode receiver of he TLE7251V are powered by he V CC supply. In case of an insufficien V CC supply, he TLE7251V can neiher ransmi he CANH and CANL signals correcly o he bus, nor can i receive hem properly. Therefore he TLE7251V blocks he ransmier and he receiver in forced sand-by mode. The low-power receiver is acive in forced sand-by mode (see Figure 7). The undervolage deecion on he ransmier supply V CC is only acive in normal-operaing mode (see Figure 5). digial supply volage VIO = on VCC VCC undervolage monior VCC(UV,F) hyseresis VCC(UV,H) VCC undervolage monior VCC(UV,R) Delay(UV) delay ime undervolage normal-operaing mode forced sand-by mode normal-operaing mode STB Assuming he STB remains low. The low signal is driven by he exernal microconroller Figure 7 Undervolage on he ransmier supply V CC 4.3.6 Volage adapion o he microconroller supply The HS CAN ransceiver TLE7251V has wo differen power supplies, V CC and V IO. The power supply V CC supplies he ransmier and he normal-mode receiver. The power supply V IO supplies he digial inpu and oupu buffers, he low-power receiver, he wake-up logic and i is also he main power domain for he inernal logic. To adjus he digial inpu and oupu levels of he TLE7251V o he I/O levels of he exernal microconroller, connec he power supply V IO o he microconroller I/O supply volage (see Figure 14).

High Speed CAN-Transceiver wih Bus Wake-up Funcional descripion 4.4 Remoe wake-up The TLE7251V has a remoe wake-up feaure, also called bus wake-up feaure. In boh sand-by mode and forced sand-by mode, he low-power receiver moniors he aciviy on he CAN bus and in case i deecs a wake-up signal, he TLE7251V indicaes he wake-up signal on he RxD oupu pin. While enering sand-by mode, he RxD oupu pin is se o logical high, regardless of he signal on he CAN bus. The low-power receiver of he TLE7251V requires a signal change from recessive o dominan on he CAN bus before he RxD oupu is enabled o follow he signals on he HS CAN bus. HS CAN bus signals, dominan or recessive, wih a pulse widh above he CAN aciviy filer ime > Filer are indicaed on he RxD oupu pin. Gliches wih a pulse widh below he CAN aciviy filer ime < Filer are ignored and no considered as a valid wake-up signal. The RxD oupu reacs wihin he reacion ime WU_Rec afer deecing a wake-up signal (see Figure 8). Noe: A wake-up even on he CAN bus is only indicaed on he RxD oupu, no auomaic change of he operaing mode is applied. To ener normal-operaing mode, he exernal microconroller needs o change he signal on he STB pin. The wake-up logic is supplied by he power supply V IO (see Figure 1). In case he TLE7251V is in sand-by mode he power supply V CC can be urned off, while he TLE7251V is sill able o deec a wake-up signal on he HS CAN bus (see also Figure 4).

A curren limiing circui proecs he ransceiver agains damages. If he device is heaing up due o a coninuous shor on he CANH or CANL, he inernal overemperaure proecion swiches off he bus ransmier. 5.2 Unconneced logic pins All logic inpu pins have an inernal pull-up resisor o V IO. In case he V IO supply is acivaed and he logical pins are open, he TLE7251V eners ino he sand-by mode by defaul. In sand-by mode he ransmier of he TLE7251V is disabled, he bus bias is urned off and he inpu resisors of CANH and CANL are conneced o GND. 5.3 TxD ime-ou funcion The TxD ime-ou feaure proecs he CAN bus agains permanen blocking in case he logical signal on he TxD pin is coninuously low. A coninuous low signal on he TxD pin migh have is roo cause in a lockedup microconroller or in a shor circui on he prined circui board, for example. In normal-operaing mode, a logical low signal on he TxD pin for he ime > TxD enables he TxD ime-ou feaure and he TLE7251V disables he ransmier (see Figure 9).

High Speed CAN-Transceiver wih Bus Wake-up Applicaion informaion 8.3 Examples for mode changes Changing he saus on he STB inpu pin riggers a change of he operaing mode, disregarding he acual signal on he CANH, CANL and TxD pins (see also Chaper 4.2). Mode changes are riggered by he STB pin, when he device TLE7251V is fully supplied. Seing he STB pin o logical low changes he mode of operaion o normal-operaing mode: The mode change is execued independenly of he signal on he HS CAN bus. The CANH, CANL inpus may be eiher dominan or recessive. They can be also permanenly shored o GND or V CC. A mode change is performed independenly of he signal on he TxD inpu. The TxD inpu may be eiher logical high or low. Analog o ha, changing he STB inpu pin o logical high changes he mode of operaion o he sand-by mode, independen on he signals a he CANH, CANL and TxD pins. Noes 1. In case he TxD signal is low seing he STB inpu pin o logical low changes he operaing mode of he device o normal-operaing mode and drives a dominan signal o he HS CAN bus. 2. The TxD ime-ou is only effecive in normal-operaing mode. The TxD ime-ou imer sars when he TLE7251V eners normal-operaing mode and he TxD inpu is se o logical low. Daa Shee 28 Rev. 1.01

High Speed CAN-Transceiver wih Bus Wake-up Applicaion informaion 8.3.1 Mode change o sand-by mode during a dominan bus signal The example in Figure 15 shows a mode change from normal-operaing mode o sand-by mode while he signal on he HS CAN bus is dominan. During he mode ransiion ime Mode, he ransceiver TLE7251V blocks he RxD oupu and provides a logical high on he RxD oupu pin. The inernal receiver swiches from he normal-mode receiver o he low-power receiver, while changing from normal-operaing mode o sand-by mode. Afer enering sand-by mode he ransceiver TLE7251V coninues o indicae a high signal on he RxD oupu as long as he HS CAN bus remains dominan. The permanen dominan bus signal is no considered as a wake-up even and herefore no indicaed on he RxD oupu pin. Deecing he firs signal change from recessive o dominan on he HS CAN bus releases he inernal wake-up logic. Wihin he wake-up reacion ime WU_Rec, a recessive CAN bus signal is indicaed on he RxD oupu pin by a logical high signal and a dominan CAN bus signal is indicaed by a logical low signal, as long he pulse widh of he HS CAN bus signals is longer han he CAN aciviy filer ime > Filer. Enering sand-by mode while he HS CAN bus signal is recessive, a release of he inernal wake-up logic is no necessary and a dominan wake-up signal ( > Filer ) on he HS CAN bus is indicaed on he RxD oupu pin wihin he wake-up reacion ime WU_Rec.(compare o Figure 8). Noe: The dominan signal on he HS CAN bus is se by anoher HS CAN bus subscriber.

The HS CAN signal is recessive, assuming all oher HS CAN bus subscribers are also sending a recessive bus signal. While he ransceiver TLE7251V is in sand-by mode, he ransmier and he normal-mode receiver are urned off. In sand-by mode he low-power receiver is acive. The TLE7251V drives no signal o he HS CAN bus, he RxD oupu is conneced o he low-power receiver and follows only he HS_CAN bus signals when is pulse widh exceeds he CAN aciviy filer ime Filer. Changing he STB o logical low urns he mode of operaion o normal-operaing mode, while he TxD inpu signal remains logical low. The ransmier and he normalmode receiver remain disabled unil he mode ransiion is compleed. During he mode ransiion he RxD oupu is blocked and se o logical high. In normal-operaing mode he ransmier and he normal-mode receiver are acive. The low signal on he TxD inpu drives a dominan signal o he HS CAN bus and he RxD oupu becomes logical low following he dominan signal on he HS CAN bus. Changing he STB pin back o logical high, disables he ransmier and normal-mode receiver again. The RxD oupu pin is blocked and se o logical high wih he sar of he mode ransiion.
