Texas Instruments TPS3423 & TPS3424 Push-Button Controllers
Texas Instruments TPS3423 and TPS3424 Nano-Power Push-Button Controllers offer a wide range of independent short-press and long-press detection. This device comes with a configurable delay to enable a battery freshness seal. The TPS3423/TPS3424 push-button controllers include up to two outputs per push button, allowing the voltage regulator or circuit breakers. These controllers feature a 1V to 6V operating voltage range, a ±8kV HBM ESD rating on the push-button pin, a typical nano supply current of 18nA, and ±10% maximum time accuracy. Typical applications include wearables, gaming consoles, home theater entertainment, printers, health care, portable electronics, and factory automation and control.
The TPS3423 and TPS3424 controllers integrate an interrupt pulse for both short- and long-press events to notify the microcontroller. The RESET output changes the device's state according to the device configuration. These controllers are RoHS compliant and available in SOT-5X3 8-pin compatible DRL package.
