Explanation:

The TPS22995 is a single-channel load switch with configurable rise time, which can minimize inrush current to the greatest extent. This device contains an N-channel MOSFET that can operate within an input voltage range of 0.4V to 5.5V and supports a maximum sustained current of 3.8A. The switch is controlled by an on-off input (ON) that can be directly connected to the low-voltage control signal. In addition, the TPS22995 features a fast output discharge function when the switch is off, which can lower the output voltage to a known 0V state. The TPS22995 comes in two different 6-pin WQFN packages and is available in 0.4mm and 0.5mm options. The rated operating temperature range of this device in a naturally ventilated environment is from -40 °C to +125°C.
