3 Description

The TPS22968x-Q1 is a small, dual-channel load

switch

with

configurable

rise

time.

The

device

contains two N-channel MOSFETs that can operate

over an input voltage range of 0.8 V to 5.5 V and can

support a maximum continuous current of 4-A 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.

The TPS22968-Q1 includes a 270

Ω on-chip resistor

for quick output discharge when the switch is turned

off.

The TPS22968x-Q1 is available in a small, space-

saving package (DMG) with wettable flanks and an

integrated thermal pad. The wettable flanks allow for

visual solder inspection. The device is characterized

for operation over the free-air temperature range of

–40 to +125°C.
