General Description

The TPS22961 is a small, ultra-low RON, single channel load switch with controlled turn on.

The device contains an N-channel MOSFET that can operate over an input voltage range of 0.8 V to 3.5 V and supports a maximum continuous current of 6 A.

The combination of ultra-low RON and high current capability of the device makes it ideal for driving processor rails with very tight voltage dropout tolerances.
