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.
