1 / 12 page TL7759 SUPPLY-VOLTAGE SUPERVISORS SLVS042D – JANUARY 1991 – REVISED JULY 1999 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Power-On Reset Generator D Automatic Reset Generation After Voltage Drop D Precision Input Threshold Voltage . . . 4.55 V ±120 mV D Low Standby Current ...20 µA D Reset Outputs Defined When VCC Exceeds 1 V D True and Complementary Reset Outputs D Wide Supply-Voltage Range ...1 V to 7 V 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.
