3 Description

channel load switch with controlled turn on. The

device contains two N-channel MOSFETs that can

operate over an input voltage range of 0.8 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. In TPS22968, a 270-

Ω on-chip load resistor

is added for output quick discharge when switch is

turned off.

The TPS22968x is available in a small, space-saving

package (DPU) with integrated thermal pad allowing

for

high

power

dissipation.

The

device

is

characterized

for

operation

over

the

free-air

temperature range of –40 to +105°C.
