General Description

The MAX16056–MAX16059 are ultra-low-current 125nA (typ) microprocessor (µP) supervisory circuits that monitor a single system supply voltage.

These devices assert an active-low reset signal whenever the V CC supply voltage drops below the factory-trimmed reset threshold, manual reset is pulled low, or the watchdog timer runs out (MAX16056/MAX16058).

The reset output remains asserted for an adjustable reset timeout period after V CC rises above the reset threshold.
