US2236090D Datasheet






The UTC US2236090D is ultra-small, low RON single channel

load switches with controlled turn on. The device contains a

P-channel MOSFET that can operate over an input voltage range

of 1.1 V to 3.6 V. The switch is controlled by an on/off input (ON),

which is capable of interfacing directly with low-voltage control

signals. In UTC  US22360904, a 85-Ω on-chip load resistor is

added for output quick discharge when switch is turned off.

The UTC  US2236090D is available in a space-saving

4-terminal WCSP 0.4-mm pitch (YFP). The devices are

characterized for operation over the free-air temperature range of

-40°C to 85°C.
