Texas Instruments TPS22968 Dual Channel Load Switch

Texas Instruments TPS22968 Dual Channel Load Switch

Texas Instruments TPS22968 Dual Channel Load Switch 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 0.8V to 5.5V and can support a maximum continuous current of 4A 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 270Ω on-chip load resistor is added for output quick discharge when switch is turned off. The TPS22968 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 85°C.
