1 / 11 page TL7757 SUPPLY-VOLTAGE SUPERVISOR AND PRECISION VOLTAGE DETECTOR SLVS041E – SEPTEMBER 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 Low Standby Current ...20 µA D Reset Output Defined When VCC Exceeds 1 V D Complementary Reset Output D True and Complementary Reset Outputs D Precision Threshold Voltage 4.55 V ±120 mV D High Output Sink Capability ...20 mA D Comparator Hysteresis Prevents Erratic Resets description 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. The TL7757C is characterized for operation from 0 °C to 70°C. The TL7757I is characterized for operation from –40 °C to 85°C.
