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.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. All voltage values are with respect to network terminal ground. 2. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) − TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability. 3. The package thermal impedance is calculated in accordance with JESD 51-7. 2 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 TL7757 SUPPLY-VOLTAGE SUPERVISOR AND PRECISION VOLTAGE DETECTOR SLVS041I − SEPTEMBER 1991 − REVISED AUGUST 2003 recommended operating conditions MIN MAX 1 7 UNIT VCC Supply voltage VOH High-level output voltage 15 V IOL Low-level output current 20 mA TA Operating free-air free air temperature TL7757C TL7757I 0 70 −40 85 V °C electrical characteristics at specified free-air temperature PARAMETER TEST CONDITIONS VIT− Negative going input threshold voltage at VCC Negative-going Vhys† Hysteresis at VCC VOL Low level output voltage Low-level IOL = 20 mA, mA 3V VCC = 4 4.3 IOH High level output current High-level VCC = 7 V, See Figure 1 VOH = 15 V, Vres‡ Power up reset voltage Power-up RL = 2.2 kΩ, VCC slew rate ≤ 5 V/µs ICC Supply pp y current TA TL7757C MIN TYP MAX 25°C 4.43 4.55 4.67 0°C to 70°C 4.4 25°C 40 0°C to 70°C 30 25°C 50 60 70 0.4 mV 0.8 V 0.8 25°C 1 0°C to 70°C 1 25°C 0.8 µA A 1 0°C to 70°C V 1.2 25°C VCC = 5.5 V V 4.7 0°C to 70°C VCC = 4 4.3 3V UNIT 1400 2000 0°C to 70°C 2000 0°C to 70°C 40 µA µ † This is the difference between positive-going input threshold voltage, VIT+, and negative-going input threshold voltage, VIT−. ‡ This is the lowest voltage at which RESET becomes active. switching characteristics at specified free-air temperature PARAMETER TEST CONDITIONS TA 25°C tPLH Propagation delay time, low low-to-high-level to high level output VCC slew rate ≤ 5 V/µs, See Figures 2 and 3 tPHL Propagation delay time, high high-to-low-level to low level output See Figures 2 and 3 tr Rise time VCC slew rate ≤ 5 V/µs, See Figures 2 and 3 tf Fall time See Figures 2 and 3 tw(min) Minimum pulse duration at VCC for output response TYP MAX 3.4 5 0°C to 70°C 25°C 5 2 0°C to 70°C 25°C 5 5 0.4 0°C to 70°C 25°C POST OFFICE BOX 655303 TL7757C MIN 1 1 0.05 1 0°C to 70°C 1 25°C 5 0°C to 70°C 5 • DALLAS, TEXAS 75265 UNIT µss µss µss µss µs 3 TL7757 SUPPLY-VOLTAGE SUPERVISOR AND PRECISION VOLTAGE DETECTOR SLVS041I − SEPTEMBER 1991 − REVISED AUGUST 2003 electrical characteristics at specified free-air temperature PARAMETER TEST CONDITIONS VIT− Negative going input threshold voltage at VCC Negative-going Vhys† Hysteresis at VCC VOL Low level output voltage Low-level IOL = 20 mA, mA VCC = 4 4.3 3V IOH High level output current High-level VCC = 7 V, See Figure 1 VOH = 15 V, Vres‡ Power up reset voltage Power-up RL = 2.2 kΩ, VCC slew rate ≤ 5 V/µs ICC Supply pp y current TA TL7757I MIN TYP MAX 4.55 4.67 25°C 4.43 −40°C to 85°C 4.4 25°C 40 −40°C to 85°C 30 25°C VCC = 5.5 V 50 0.4 25°C 1 −40°C to 85°C 1 0.8 −40°C to 85°C V µA A 1 1.2 1400 mV 0.8 0.8 25°C V 60 70 −40°C to 85°C 25°C 4.3 3V VCC = 4 4.7 UNIT V 2000 −40°C to 85°C 2100 −40°C to 85°C 40 µA µ † This is the difference between positive-going input threshold voltage, VIT+, and negative-going input threshold voltage, VIT−. ‡ This is the lowest voltage at which RESET becomes active. switching characteristics at specified free-air temperature PARAMETER TEST CONDITIONS TA 25°C tPLH time low-to-high-level low to high level output Propagation delay time, VCC slew rate ≤ 5 V/µs, See Figures 2 and 3 tPHL Propagation delay time, time high-to-low-level high to low level output See Figures 2 and 3 tr Rise time VCC slew rate ≤ 5 V/µs, See Figures 2 and 3 tf Fall time See Figures 2 and 3 tw(min) Minimum pulse duration at VCC for output response MAX 3.4 5 5 2 −40°C to 85°C 25°C 5 5 0.4 −40°C to 85°C 25°C POST OFFICE BOX 655303 TYP −40°C to 85°C 25°C 4 TL7757I MIN 1 1 0.05 1 −40°C to 85°C 1 25°C 5 −40°C to 85°C 5 • DALLAS, TEXAS 75265 UNIT µss µss µss µss µs TL7757 SUPPLY-VOLTAGE SUPERVISOR AND PRECISION VOLTAGE DETECTOR SLVS041I − SEPTEMBER 1991 − REVISED AUGUST 2003 PARAMETER MEASUREMENT INFORMATION 15 V VCC + 5.5 V A TL7757 RESET − GND Figure 1.
