Smart Phone Battery Switch
Controller
Description
CAT874 is a switch controller designed to start/shut off smart
phones with the push button input or by phone microcontroller unit.
CAT874 monitors two inputs and outputs an active high output after
PWR_ON input has been active (logic low) for a factory preset
minimum time. Releasing input from its active state before the
minimum timeout period resets the internal timer and must return to
being active before the timer will restart with a fresh count down. The
output remains high until the next PWR_ON hightolow or VCHG
lowtohigh transition.
CAT874’s push pull output is capable of sinking up to 3 mA of
current.
