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).
