General Description The MAX6701 microprocessor (µp) supervisory circuits reduce the complexity and components required to monitor power-supply functions in µp systems. These devices significantly improve system reliability and accuracy compared to separate ICs or discrete components. The MAX6701 family provides four functions: a reset output during power-up, power-down, and brownout conditions; an independent watchdog output that goes low if the watchdog input has not been toggled within 1.6s; a 0.62 threshold detector for power-fail warning; and an active-low manual reset input. The MAX6701 family offers several pinout options to accommodate a variety of multivoltage microprocessor supervision applications. The MAX6701(A)/MAX6702(A)/MAX6703(A) monitor three supply voltages (one fixed threshold and two adjustable) to drive a single reset output and include a manual reset input and a watchdog timer with an independent output. The MAX670 monitors a single-supply voltage to drive complementary reset outputs and includes an independent adjustable power-fail-in/powerfail-out comparator, a manual reset input, and a resetbased watchdog timer. The MAX670(A)/MAX6706(A)/ MAX6707(A) monitor a single-supply voltage to drive a single reset output and include an independent adjustable power-fail-in/power-fail-out comparator, a manual reset input, and a watchdog timer with an independent output. The is the same as the MAX670 but without the watchdog timer function. See the Detailed Description for differences between non-a and A versions.

Reset Output A microprocessor s (µp s) reset input starts the µp in a known state. The MAX6701 assert reset during power-up and prevent code execution errors during power-down or brownout conditions. On power-up, once reaches 1, is a guaranteed logic-low of 0. or less. As rises, stays low. After, RST_IN1, or RST_IN2 rise above the reset threshold, an internal timer holds low for about 200ms. pulses low whenever dips below the reset threshold, including brownout conditions. If a brownout occurs in the middle of a previously initiated reset pulse, the pulse continues for at least another 10ms. On power-down, once falls below the reset threshold, stays low and is guaranteed to be 0. or less, until drops below 1. The MAX6702(A)/MAX670/MAX6706(A)/ active-high output is the complement of the output, and is guaranteed to be valid with down to 1. www.maximintegrated.com Maxim Integrated 6

Standard- vs. A-ersion Comparison The MAX6701/MAX6702/MAX6703/MAX670/MAX6706/ MAX6707s latches low when one of the following events occurs: The watchdog timer times out (1.6s, typ)., RST_IN1, or RST_IN2 is below its reset threshold. is pulled low. only deasserts with a valid transition. The MAX6701(A)/MAX6702(A)/MAX6703(A)/MAX670(A)/ MAX6706(A)/ MAX6707(A)s asserts when either, RST_IN1, or RST_IN2 is below its reset threshold. deasserts without a timeout delay when the undervoltage situation has expired. is latched low when the watchdog timer elapses without seeing a transition. deasserts with a valid transition OR by pulling low. See Figures and for standard-version timing. See Figures 6 and 7 for A-version timing. Watchdog Timer The MAX6701 MAX6707 watchdog circuit monitors the µp s activity. If the µp does not toggle the within 1.6s, goes low. When is asserted, the watchdog timer stays cleared and does not count. As soon as reset is released, the timer starts counting. deasserts after a valid transition is detected at. Pulses as short as 0ns can be detected. Typically, is connected to the NMI input of a µp. When, RST_IN1, or RST_IN2 drop below the reset threshold, goes low whether or not the watchdog timer has timed out. Normally this would trigger an NMI, but goes low simultaneously, and thus overrides the NMI. The MAX670 watchdog circuit does not have an independent watchdog output (). If the µp does not toggle the watchdog input within 1.6s, the MAX670 asserts a reset output pulse for the reset timeout period. Manual Reset The manual reset input () allows reset to be triggered by a pushbutton switch. The switch is effectively debounced by the reset pulse width. is CMOS logic compatible, so it can be driven by an external logic line. can be used to force a watchdog timeout to generate a reset pulse in the MAX6701(A)/MAX6702(A)/ MAX6703(A)/MAX670(A)/MAX6706(A)/MAX6707(A) by connecting to. Power-Fail Comparator The uncommitted power-fail comparator can be used for various purposes because its noninverting input and output are externally available. The inverting input is internally connected to a 0.62 reference. To build an early warning circuit for power failure, connect the PFI pin to a voltage-divider (see the Typical Operating Circuit). Choose the voltage-divider ratio so that the voltage at PFI falls below 0.62 just before the regulator drops out. Use to interrupt the µp so it can prepare for an orderly power-down. The low-input current at this pin allows for large resistor values in the divider. t t WD t WD TH TH t RP t RP () ( ) ARE FOR MAX6702/MAX6706 ONLY. EXTERNALLY TRIGGERED BY t RP t MD t Figure.

Calculating Adjustable oltage Thresholds Reset Input The MAX6701(A)/MAX6702(A)/MAX6703(A) include two adjustable reset inputs for monitoring up to a total of three system voltages (including ). The thresholds for the monitored RST_IN supplies are externally set with resistor-divider networks (Figure 8). The reset output is asserted if any of the monitored supplies (, RST_IN1, or RST_IN2) go below its specified threshold and remains asserted for the reset timeout period after all supplies are above their thresholds. Applications Information Ensuring a alid Output Down to = 0 When falls below 1, the MAX6701 output no longer sinks current; it becomes an open circuit. High-impedance CMOS logic inputs can drift to undetermined voltages if left undriven. If a pulldown resistor is added to the pin, as shown in Figure 9, any stray charge or leakage currents are drained to ground, holding low. A resistor value (R1) is not critical; 100kΩ is large enough not to load and small enough to pull to ground. This application works for push-pull output only (not for open-drain resets). Monitoring Other System oltages Other systems can be monitored by connecting a voltage-divider to PFI and adjusting the ratio appropriately. In noisy systems, a capacitor between PFI and GND reduces the power-fail circuit s sensitivity to highfrequency noise on the line being monitored. Reset can be asserted on other voltages in addition to the supply line. Connect to to initiate a reset output pulse when PFI drops below 0.62. Figure 10 shows the MAX670 configured to assert a reset output when the secondary supply falls below the reset threshold. Generating a Reset from Watchdog Overflow Connect to to force a watchdog timeout to generate a reset pulse for only the reset timeout period on the MAX6701(A)/MAX6702(A)/MAX6703(A)/MAX670(A)/ MAX6706(A)/MAX6707(A). When the MAX670 watchdog times out, reset outputs are automatically asserted (no external connections required).
