3 Description

The TPS22966 is a small, low RON, dual-channel load

switch with controlled turnon. The device contains two

N-channel MOSFETs that can operate over an input

voltage range of 0.8 V to 5.5 V and can support a

maximum continuous current of 6 A per channel.

Each switch is independently controlled by an on and

off input (ON1 and ON2), which can interface directly

with low-voltage control signals. In TPS22966, a 220-

Ω on-chip load resistor is added for quick-output

discharge when switch is turned off.

The TPS22966 is available in a small, space-saving

2-mm × 3-mm 14-SON 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°C to

+105°C.
