The Texas Instruments TPS22945DCKRG4 is a P-channel load switch designed for high-side power distribution. This device features a 1:1 input-to-output ratio and supports a maximum continuous output current of 100mA. It incorporates integrated fault protection mechanisms, including fixed current limiting, over-temperature shutdown, and undervoltage lockout (UVLO), with auto-restart functionality. The TPS22945DCKRG4 operates over a temperature range of -40°C to 125°C (TJ) and is housed in a compact SC-70-5 package, suitable for surface mounting. Key electrical characteristics include a typical ON-resistance (Rds On) of 400mOhm and a load voltage range of 1.62V to 5.5V. The interface for control is via an ON/OFF pin. This component is utilized in various applications, including portable electronics and consumer devices.
