? Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. 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 the network ground terminal.
             2. For proper operation of the TL7702A, the voltage applied to the SENSE terminal should not exceed VCC 1 V or 6 V, whichever is less.
             3. Maximum power dissipation is a function of TJ(max), JA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) TA)/JA. Operating at the absolute maximum TJ of 150°C can impact reliability.
             4. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace length of zero.


Description

The TL77xxA family of integrated-circuit supply-voltage supervisors is specifically designed for use as reset controllers in microcomputer and microprocessor systems. The supply-voltage supervisor monitors the supply for undervoltage conditions at the SENSE input. During power up, the RESET output becomes active (low) when VCC attains a value approaching 3.6 V. At this point (assuming that SENSE is above VIT+), the delay timer function activates a time delay, after which outputs RESET and RESET go inactive (high and low, respectively). When an undervoltage condition occurs during normal operation, outputs RESET and RESET go active. To ensure that a complete reset occurs, the reset outputs remain active for a time delay after the voltage at the SENSE input exceeds the positive-going threshold value. The time delay is determined by the value of the external capacitor CT: td = 1.3 * 104 * CT, where CT is in farads (F) and td is in seconds (s).

During power down (assuming that SENSE is below VIT), the TL77xxA outputs remain active until the VCC falls below a maximum of 2 V. After this, the outputs are undefined.

An external TL77xxA capacitor (typically 0.1 µF for the TL77xxAC and TL77xxAI) must be connected to REF to reduce the influence of fast transients in the supply voltage.

The TL77xxAC series is characterized for operation from 0°C to 70°C. The TL77xxAI series is characterized for operation from 40°C to 85°C.
