Description
The TL77xxA family of integrated-circuit supply-voltage supervisors is designed specifically 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, 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 C T: td= 1.3 × 104 × C T, where C T is in farads (F) and td
is in seconds (s).
During power down and when SENSE is below VIT–, the outputs remain active until VCC falls below 2 V.
After this, the outputs are undefined.
