3 Description
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.
