(1) See the Application Information section for CT value vs. rise

time

(2) This feature discharges the output of the switch to GND

through a 270-Ω resistor, preventing the output from floating.

3 Description

The TPS22968x is a small, ultra-low RON, dualchannel

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 and off input (ON1 and ON2),

which is capable of interfacing directly with lowvoltage

control signals. In TPS22968, a 270-Ω onchip

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.
