The TL7702ACD is a single-supply Voltage Supervisor with programmable UV threshold and reset time delay. It is designed specifically for use as reset controllers in microcomputer and microprocessor systems. The supply-voltage supervisor monitors the supply for under-voltage conditions at the SENSE input. During power-up, the /RESET output becomes active (low) when VCC attains a value approaching 3.6V. At this point (assuming that SENSE is above VIT+), the delay timer function activates a time delay, after which outputs /RESET and RESET go inactive (high and low, respectively). When an under-voltage condition occurs during normal operation, /RESET and RESET go active.
