Description

The TL77xxA family of integrated-circuit supply-voltage supervisors is designed specifically for use as reset controllers in microcomputer and microprocessor systems. The supply-voltage supervisor monitors the supply for undervoltage conditions at the SENSE input. During power up, theRESEToutput becomes active (low) when VCCattains a value approaching 3.6 V. At this point (assuming that SENSE is above VIT+), the delay timer function activates a time delay, after which outputsRESETand RESET go inactive (high and low, respectively). When an undervoltage condition occurs during normal operation,RESETand RESET go active.
