3 Description

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.
