The TPS22968x is a small, ultra-low RON, dual-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 and 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.
