FEATURES

DESCRIPTION

•

Integrated Single Load Switch

•

Input Voltage: 0.75 V to 3.6 V

with controlled turn on. The device contains a N-

•

Ultra-Low ON Resistance

channel MOSFET that can operate over an input

voltage range of 0.75 V to 3.6 V. An integrated

–

charge pump biases the NMOS switch to achieve a

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

quick discharge when the switch is turned off. The

–

rise time of the device is internally controlled to avoid

inrush current. The TPS22924B features a rise time

0.9 mm x 1.4 mm, 0.5-mm Pitch

of 100 µs at 3.6 V.

•

2-A Maximum Continuous Switch Current

The TPS22924B is available in an ultra-small space-

•

operation over the free-air temperature range of

–40ºC to 85ºC.

•

Controlled Slew Rate to Avoid Inrush Currents

•

Quick Output Discharge Transistor
