General Description
The MAX792/MAX820 microprocessor (μP) supervisory circuits provide the most functions for power-supply and watchdog monitoring in systems without battery backup. Built-in features include the following:
? μP reset: Assertion of RESET and RESET outputs during
?? power-up, power-down, and brownout conditions.
?? RESET is guaranteed valid for VCC down to 1V.
? Manual-reset input.
? Two-stage power-fail warning: A separate low-line
?? comparator compares VCC to a preset threshold
?? 120mV above the reset threshold; the low-line and
?? reset thresholds can be programmed externally.
? Watchdog fault output: Assertion of WDO if the watchdog
?? input is not toggled within a preset timeout
?? period.
? Pulsed watchdog output: Advance warning of
?? impending WDO assertion from watchdog timeout that
?? causes hardware shutdown.
? Write protection of CMOS RAM, EEPROM, or other
?? memory devices.
??
The MAX792 and MAX820 are identical, except the MAX820 guarantees higher low-line and reset threshold accuracy (±2%).
Features
? Manual-Reset Input
? 200ms Power-OK/Reset Time Delay
