TL7759CD

电源电压监事 SUPPLY-VOLTAGE SUPERVISORS

description

The TL7759 is a supply-voltage supervisor designed for use as a reset controller in microcomputer and microprocessor systems. The supervisor monitors the supply voltage for undervoltage conditions. During power up, when the supply voltage, VCC, attains a value approaching 1 V, the RESET and RESEToutputs become active high and low, respectively to prevent undefined operation.
