TPS3423 and TPS3424 are push-button controllers which offer wide range of independent short press and long press functionality. These devices offer up to two outputs per push-button (RESET and INT), which can be used for various use cases including enabling the voltage regulator or circuit breakers, sending an interrupt to micro controller and generating logic. The device generates an interrupt pulse both for short press and long press notifying the micro controller. RESET output changes the state based on the device configuration.

By controlling the power tree running off the battery, TPS3423/4 extends battery life and prolongs device shelf life. This feature is also known as battery freshness seal.

TPS3423/4 are offered in fixed timing options for short and long press durations. To provide flexibility to the designer, TPS3424 also offers user-programmable short and long press durations through an external capacitor. Kill pin in TPS3424 enables feedback from the microcontroller to asynchronously de-assert RESET.
