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 outputs remain active until the VCC falls below
a maximum of 2 V. After this, the outputs are undefined.
An external capacitor (typically 0.1
F 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.
