TPS22924x 3.6-V, 2-A, 18.3-m

Ω On-Resistance Load Switch

1 Features

3 Description

1

•

Integrated Single Load Switch

controlled turn on. The device contains a N-channel

•

Input Voltage: 0.75 V to 3.6 V

MOSFET that can operate over an input voltage

•

On-Resistance

range of 0.75 V to 3.6 V. An integrated charge pump

biases the NMOS switch to achieve a minimum

–

switch ON resistance. The switch is controlled by an

–

on/off input (ON), which is capable of interfacing

–

directly with low-voltage control signals.

–

A 1250

Ω on-chip load resistor is added for output

Small CSP-6 package

quick discharge when the switch is turned off. The

0.9 mm x 1.4 mm, 0.5-mm Pitch

rise time of the device is internally controlled to avoid

inrush current. The TPS22924B features a rise time
