APPLICATIONS INFORMATION
4.1
Operation – Power Monitor
The TC1272/TC1273/TC1274 is designed to function
as a voltage monitor for +5V systems. These devices
provide a RESET signal to indicate that the VCC has
dropped below a preset voltage level that is selected by
the suffix part number. In addition, the RESET is held
active for approximately 200 ms after the power supply
has risen above the voltage threshold level to allow
time for the power supply to stabilize before system
operation commences.
