MAX820 Product details

Description

The MAX792/MAX820 microprocessor (µP) supervisory circuits provide the most functions for power-supply and watchdog monitoring in systems without battery backup.

Features

include the following: 1) 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. 2) Manual-reset input. 3) 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. 4) Watchdog fault output: Assertion of WDO if the watchdog input is not toggled within a preset timeout peri.
