FEATURES

DESCRIPTION

•

Integrated dual channel load switch

The TPS22966 is a small, ultra-low RON, dual

•

Input voltage range: 0.8V to 5.5V

channel load switch with controlled turn on. The

device contains two N-channel MOSFETs that can

•

operate over an input voltage range of 0.8V to 5.5V

–

and can support a maximum continuous current of 6A

–

per channel. Each switch is independently controlled

–

by an on/off input (ON1 and ON2), which is capable

of interfacing directly with low-voltage control signals.

•

6A maximum continuous switch current per

In TPS22966, a 220-

Ω on-chip load resistor is added

channel

for quick output discharge when switch is turned off.

•

Low quiescent current

The TPS22966 is available in a small, space-saving
