TL7705BID

The TL7705BID is a single-supply Voltage Supervisor for 5V systems with programmable time delay. The integrated-circuit supply-voltage supervisor designed 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 1V. As VCC approaches 3V (assuming that SENSE is above VT+), 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, outputs /RESET and RESET go active. To ensure that a complete reset occurs, the reset outputs remain active for a time delay after the voltage at the SENSE input exceeds the positive-going threshold value.
