Switch Controller

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 PWRON input has been active (logic low) or 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 PWRON high-to-low or VCHG low-to-high transition. CAT874's push pull output is capable of sinking up to 3 mA of current.
