Product Summary

The TL7733BCDR is an integrated-circuit supply-voltage supervisor designed for use as reset controllers in microcomputer and microprocessor systems. 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 1 V. As VCC approaches 3 V (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 undervoltage condition occurs during normal operation, outputs RESET and RESET go active.
