The TPS22950x is a single channel load switch with a 34-mΩ power MOSFET capable of driving loads up to 3.2 A. While on, the device provides protection against fault cases though its adjustable output current limiting and thermal shutdown. The TPS22950 responds to overcurrent events with auto-retry behavior, while the TPS22950L uses a debounce time and latch off behavior. The TPS22950 also provides reverse current blocking for when VOUT exceeds VIN.

The switch ON state is controlled by a digital input that is capable of interfacing directly with low-voltage control signals, and a smart pulldown is used to keep the ON pin from floating until system sequencing is complete. When the device is turned off, quick output discharge is enabled, pulling the output voltage down to 0 V through a resistive path to GND.
