DESCRIPTION

•

Integrated Single-Channel Load Switch

•

Ultra Small CSP-4 package

The TPS22934 is a small, ultra low ON-resistance

0.9 mm x 0.9 mm, 0.5-mm Pitch, 0.5-mm Thick

contain a P-channel MOSFETs that can operate over

•

Input Voltage: 1.5 V to 3.6 V

an input voltage range of 1.5 V to 3.6 V.

•

Ultra-Low ON Resistance

The switch is controlled by an on/off input (ON),

–

–

allowing an easy use of TPS22934 in power-rail

sequencing applications.

–

–

In TPS22934 a 35-

Ω on-chip load resistor is added

for output quick discharge when switch is turned off.

•
