APPLICATIONS INFORMATION
3.1
Operation – Power Monitor
The TC1278/TC1279 provide the function of detecting
out-of-tolerance power supply conditions and warning
a processor-based system of impending power failure.
When V
CC
is detected as out-of-tolerance, the RESET
signal is asserted. On power-up, RESET is kept active
for approximately 350msec after the power supply has
reached the selected tolerance. This allows the power
supply and microprocessor to stabilize before RESET
is released.
