3 Description

The TPS22967 device is a small, ultra-low RON,

single-channel load switch with controlled turnon. The device contains an N-channel MOSFET that can

operate over an input voltage range of 0.8 V to 5.5 V

and can support a maximum continuous current of

4 A. The switch is controlled by an on/off input (ON),

which can interface directly with low-voltage control

signals. In the TPS22967, a 225-Ω pulldown resistor

is added for quick output discharge when the switch

is turned off.

The TPS22967 is available in a small, space-saving

2-mm × 2-mm 8-pin WSON package (DSG) with

integrated thermal pad allowing for high power dissipation. The device is characterized for operation

over the free-air temperature range of –40°C to 85°C.
