General Description

The MAX6884/MAX6885 EEPROM-configurable, multi voltage power-supply supervisors monitor six voltage detector inputs, one auxiliary input, and one watchdog input, and feature three programmable outputs for highly configurable power-supply monitoring applications. Manual reset and margin disable inputs offer additional flexibility.
