The TPS22944 is a load switch IC from Texas Instruments that provides protection to systems and loads in high-current conditions1. It contains a 0.4-Ω current-limited P-channel MOSFET that can operate over an input voltage range of 1.62 V to 5.5 V12. The device is designed to prevent current from flowing when the MOSFET is off. The IC has a maximum current rating of 100 mA and a maximum on-resistance of 500 mΩ2. The TPS22944 series is part of the TPS2294x family of low-input-voltage current-limited load switches with shut-off and auto-restart feature. The ICs in this family are designed to operate with input voltages as low as 1.62 V, making them ideal for use in battery-powered applications. The TPS22944 IC is available in a 5-pin SC-70 package and has an operating temperature range of -40°C to 85°C.
