Reset switch, TL7702ACD, Texas Instruments
The TL7702ACD is an integrated-circuit supply-voltage supervisor designed specifically for use as a reset controller in a microcomputer or microprocessor system. The supply-voltage supervisor 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 the RESET and RESET outputs go inactive (high and low, respectively). When an undervoltage condition occurs during normal operation, the RESET and RESET outputs become active.
