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.
