1 / 20 page TL7757 SUPPLY-VOLTAGE SUPERVISOR AND PRECISION VOLTAGE DETECTOR SLVS041I − SEPTEMBER 1991 − REVISED AUGUST 2003 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Power-On Reset Generator D Automatic Reset Generation After Voltage Drop D Low Standby Current...20 µA D RESET Output Defined When V CC Exceeds 1 V D Precision Threshold Voltage 4.55 V ±120 mV D High Output Sink Capability . . . 20 mA D Comparator Hysteresis Prevents Erratic Resets description/ordering information The TL7757 is a supply-voltage supervisor designed for use 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 output becomes active (low) to prevent undefined operation. If the supply voltage drops below threshold voltage level (VIT−), the RESET output goes to the active (low) level until the supply undervoltage fault condition is eliminated.
