The TPS22995H-Q1 is a single-channel load switch that contains a 19-mΩ N-channel MOSFET that can operate over an input voltage range of 0.8 V to 5.5 V and can support a maximum continuous current of 3 A.

The switch is controlled by an on and off input (ON), which is capable of interfacing directly with low voltage GPIO signals. The TPS22995H-Q1 has a Quick Output Discharge when switch is turned off, pulling the output voltage down to a known 0-V state. Additionally, the device provides an adjustable rise to limit inrush currents with high capacitive loads.

The pins of the TPS22995H-Q1 are resistant to high humidity conditions, meaning that the device is able to function with a 100-kΩ short from any pin to GND or power. When the timing pin (RT) is affected by high humidity, timing is expected to stay within +/–20%.

The TPS22995H-Q1 is available in a 2.8-mm × 2.9-mm, 0.5-mm pitch, 6-pin SOT package. The device is characterized for operation over the free-air temperature range of –40°C to +125°C.
