The is a single-supply Voltage Supervisor for 5V systems with programmable time delay. The integrated-circuit supply-voltage supervisor 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.
