3 Description

The TPS22995 is a single-channel load switch that

provides a configurable rise time to minimize inrush

current. The device contains an N-channel MOSFET

that can operate over an input voltage range of 0.4

V to 5.5 V and can support a maximum continuous

current of 3.8 A.

The switch is controlled by an on and off input

(ON), which is capable of interfacing directly with low

voltage control signals. The TPS22995 also has a

Quick Output Discharge when the switch is turned off,

pulling the output voltage down to a known 0-V state.

The TPS22995 is available in two different 6-pin

WQFN packages with both 0.4-mm and 0.5-mm

options. The device is characterized for operation

over the free-air temperature range of –40°C to

+125°C.
