3 Description
The TPS22903 and TPS22904 are ultra-small, low
rON single channel load switches with controlled
turnon. 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 and off
input (ON), which is capable of interfacing directly
with low-voltage control signals. In TPS22904, a 85-Ω
on-chip load resistor is added for output quick
discharge when switch is turned off.
TPS22903 and TPS22904 are 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.
