Product Summary
The TL7705ACDR is a supply-voltage supervisor, designed specifically for use as reset controller in microcomputer and microprocessor systems. The TL7705ACDR monitors the supply for undervoltage conditions at the SENSE input. During power up, the RESET output becomes active (low) when VCC attains 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 output RESET and RESET go inactive (high and low, respectively).
