TPS3423 and TPS3424 are push-button controllers which offer wide range of independent detection of 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, generating a monoshot for given press duration and sending an interrupt to micro controller. 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.

The extreme low power consumption 18nA helps to improve product shelf life for battery powered devices. The device keeps the power tree disabled until required button press is detected. This feature is 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.
