TL7705A

具有可编程时间延迟的 5V 系统的单电源电压监控器

The TL77xxA family of integrated-circuit supply-voltage supervisors is designed specifically 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 3.6 V. 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 undervoltage condition occurs during normal operation, RESET and RESET go active.
