Funcional Descripion 4 Funcional Descripion 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 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 TLE6251D is a High Speed CAN ransceiver wih a dedicaed bus wake-up funcion and defined by he inernaional sandard ISO 11898-2. 4.1 High Speed CAN Physical Layer TxD CAN_H CAN_L V CC = Digial supply V CC = High Speed CAN power supply TxD = Inpu from he microconroller RxD = Oupu o he microconroller CANH = Volage on he CANH inpu/oupu CANL = Volage on he CANL inpu/oupu V DIFF = Differenial volage beween CANH and CANL V DIFF = V CANH V CANL V DIFF dominan V DIFF = ISO Level dominan recessive V DIFF = ISO Level recessive RxD Figure 3 High Speed CAN bus signals and logical signals Daa Shee 6 Rev. 1.0, 2012-07-27
Funcional Descripion The TLE6251D 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 up o 1 Mbps. The characerisics for a HS CAN nework are he wo signal saes on he CAN bus: dominan and recessive (see Figure 3). The CANH and CANL pins are he inerface o he CAN bus and boh pins operae as an inpu and oupu. The RxD and TxD pins are he inerface o he microconroller. The TxD pin is he serial daa inpu from he CAN conroller, he RxD pin is he serial daa oupu o he CAN conroller. As shown in Figure 1, he HS CAN ransceiver TLE6251D includes a receiver and a ransmier uni, allowing he ransceiver o send daa o he bus medium and monior he daa from he bus medium a he same ime. The HS CAN ransceiver TLE6251D convers he serial daa sream which is available on he ransmi daa inpu TxD, ino a differenial oupu signal on he CAN bus, provided by he pins CANH and CANL. The receiver sage of he TLE6251D moniors he daa on he CAN bus and convers hem o a serial, single-ended signal on he RxD oupu pin. A logical low signal on he TxD pin creaes a dominan signal on he CAN bus, followed by a logical low signal on he RxD pin (see Figure 3). The feaure, broadcasing daa o he CAN bus and lisening o he daa raffic on he CAN bus simulaneously is essenial o suppor he bi-o-bi arbiraion wihin CAN neworks. The volage levels for HS CAN ransceivers are defined by he ISO 11898-2 and he ISO 11898-5 sandards. Wheher a daa bi is dominan or recessive depends on he volage difference beween he CANH and CANL pins: V DIFF = V CANH - V CANL. In comparison wih oher differenial nework proocols, he ampliude of he differenial signal on a CAN nework can only be higher han or equal o 0 V. To ransmi a dominan signal o he CAN bus, he ampliude of he differenial signal V DIFF is higher han or equal o 1.5 V. To receive a recessive signal from he CAN bus, he ampliude of he differenial V DIFF is lower han or equal o 0.5 V. Parially-supplied High Speed CAN neworks are neworks in which he CAN bus nodes of one common nework have differen power supply condiions. Some nodes are conneced o he common power supply, while oher nodes are disconneced from he power supply and in power-down sae. Regardless of wheher he CAN bus subscriber is supplied or no, each subscriber conneced o he common bus media mus no inerfere wih he communicaion. The TLE6251D is designed o suppor parially-supplied neworks. In he power-down sae, he receiver inpu resisors are swiched off and he ransceiver inpu has a high resisance. For permanenly supplied ECUs, he HS CAN ransceiver TLE6251D provides a sand-by mode. In sand-by mode, he power consumpion of he TLE6251D is opimized o a minimum, while he device is sill able o recognize wake-up paerns on he CAN bus and signal a wake-up even o he exernal microconroller. The volage level on he digial inpu TxD and he digial oupu RxD is deermined by he power supply level a he pin. Depending on he volage level a he pin, he signal levels on he logic pins (STB, TxD and RxD) are compaible wih microconrollers having a 5 V or 3.3 V I/O supply. Usually, he power supply of he ransceiver is conneced o he same power supply as he I/O power supply of he microconroller. Daa Shee 7 Rev. 1.0, 2012-07-27
Funcional Descripion 4.2 Modes of Operaion Two differen modes of operaion are available on he TLE6251D. Each mode has specific characerisics in erms of quiescen curren or daa ransmission. The digial inpu pin STB is used for he mode selecion. Figure 4 illusraes he differen mode changes depending on he saus of he STB pin. Afer supplying V CC and o he HS CAN ransceiver, he TLE6251D sars in sand-by mode. The inernal pull-up resisor a he STB pin ses he TLE6251D o sand-by mode by defaul. If he microconroller is up and running, he TLE6251D can swich o any operaing mode wihin he ime period for mode change MODE. undervolage deecion on V CC and V CC < V CC(UV) < (UV) sar up supply V CC and power-down sand-by mode STB = 1 STB = 0 STB = 1 normal-operaing mode STB = 0 Figure 4 Mode of operaion The TLE6251D has 2 major modes of operaion: Sand-by mode Normal-operaing mode Table 2 Modes of Operaion Mode STB Bus Bias Commen Normaloperaing mode Sand-by mode V CC on on Sand-by mode V CC off on Power-down sae V CC off off low V CC /2 The ransmier is acive.

Funcional Descripion 4.3 Normal-operaing Mode In he normal-operaing mode, he HS CAN ransceiver TLE6251D sends he serial daa sream on he TxD pin o he CAN bus. The daa on he CAN bus is displayed a he RxD pin simulaneously. In normal-operaing mode, all funcions of he TLE6251D are acive: The ransmier is acive and drives daa from he TxD o he CAN bus. The receiver is acive and provides he daa from he CAN bus o he RxD pin. The low-power receiver is disabled. The bus basing is se o V CC /2. The undervolage monioring on he power supply V CC and on he power supply is acive. The overemperaure proecion is acive. To ener he normal-operaing mode, se he STB pin o logical low (see Table 2 or Figure 4). The STB pin has an inernal pull-up resisor o he power-supply. 4.4 Sand-by Mode Sand-by mode is an idle mode of he TLE6251D wih opimized power consumpion. In sand-by mode, he TLE6251D can no send or receive any daa. The normal mode receiver is swiched off and only he low-power receiver is acive. 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 bus wake-up ime WU are indicaed a he RxD oupu pin. The ransmier is disabled, and permanenly recessive. The inpu TxD is disabled. The normal mode receiver is disabled. The low-power receiver is acive. The RxD oupu is high, in case no wake-up signal on he CAN bus is deeced (see Figure 5). The RxD oupu oggles according o he wake-up signal on he CAN bus (see Figure 5). The undervolage monioring on he power supply V CC is disabled. The undervolage monioring on he power supply is acive. The bus biasing is se o GND. The overemperaure proecion is no acive. To ener he sand-by mode, se he pin STB o logical high (see Table 2 or Figure 4). The STB pin has an inernal pull-up resisor o he power-supply. In case he sand-by mode is no be used in he final applicaion, he STB pin needs o ge conneced o GND. 4.5 Power-down Sae The power-down sae means ha he TLE6251D is no supplied. In he power-down sae, he differenial inpu resisors of he receiver are swiched off. The CANH and CANL bus inerface of he TLE6251D acs as a highimpedance 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 CAN nework. Daa Shee 9 Rev. 1.0, 2012-07-27
Funcional Descripion 4.6 Remoe Wake-up The TLE6251D has a remoe wake-up feaure, also called bus wake-up feaure. In sand-by mode, he low-power receiver moniors he aciviy on he CAN bus and in case i deecs a wake-up signal, he TLE6251D indicaes he wake-up signal on he RxD oupu pin. While enering ino sand-by mode by seing he STB pin o logical high, he RxD oupu pin is se o logical high, regardless of he signal on he CAN bus. The low-power receiver of he TLE6251D requires a signal change from recessive o dominan on he CAN bus before he RxD oupu is enabled and follows he signal on he CAN bus. CAN bus signals, dominan or recessive, wih a pulse widh above he bus wake-up ime > WU are indicaed on he RxD oupu pin (see Figure 5). The wake-up logic is supplied by he power supply (see Figure 1). In case he TLE6251D is in sand-by mode, he power supply V CC can be urned off, while he TLE6251D is sill able o deec he wake-up paern on he CAN bus. = WU = WU = WU = WU CANH CANL V DIFF = CANH - CANL V DIFF RxD STB Figure 5 Wake-up paern 4.7 Volage Adapion o he Microconroller Supply The HS CAN ransceiver TLE6251D has wo differen power supplies, V CC and. The power supply V CC supplies he ransmier and he normal mode receiver, he power supply supplies he digial inpu and oupu buffers, he low-power receiver and he wake-up logic. To adjus he digial inpu and oupu levels of he TLE6251D o he I/O levels of he exernal microconroller, he power supply should be conneced o he microconroller pad supply (see Figure 13). Supplying he low-power receiver by he pin allows o swich off he V CC supply in sand-by mode and leads o an addiional reducion of he quiescen curren in sand-by mode. Daa Shee 10 Rev. 1.0, 2012-07-27

A curren limiing circui proecs he ransceiver agains damages. If he device heas up due o a coninuous shor on he CANH or CANL, he inernal overemperaure proecion swiches off he bus ransmier. 5.2 Unconneced Logical Pins All logical inpu pins have an inernal pull-up resisor o. In case he supply is acivaed and he logical pins are open or floaing, he TLE6251D eners he sand-by mode by defaul. In sand-by mode, he ransmier of he TLE6251D is disabled, he bus bias is urned off and he inpu resisors of CANH and CANL are conneced o GND. The HS CAN ransceiver TLE6251D will no influence he daa on he CAN bus. 5.3 TxD Time-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 can have is roo cause in a locked-up microconroller or in a shor 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 TLE6251D disables he ransmier (see Figure 6).

Disregarding he signal on he CAN bus, he HS CAN ransceiver TLE6251D can change is operaing mode from normal-operaing mode o sand-by mode and vice versa. While enering sand-by mode by seing he STB pin o logical high, he RxD oupu pin is se o logical high, regardless if he CAN bus signal is recessive or dominan. In sand-by mode he TLE6251D requires a mode change from recessive o dominan once, before he RxD oupu follows he signals on he CAN bus.
