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 RESET outputs become

active (high and low, respectively) to prevent undefined operation. If the supply voltage drops below the input

threshold voltage level (VIT– ), the reset outputs go to the reset active state until the supply voltage has returned

to its nominal value (see timing diagram).

The TL7759C is characterized for operation from 0°C to 70°C.
