3 Description
The TPS22907 is a small, low RON load switch with
controlled turnon. The device contains a P-channel
MOSFET that operates 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 can interface directly with low-
voltage control signals.
The TPS22907 is available in a space-saving 4-
terminal WCSP with 0.5-mm pitch (YZT). The device
is characterized for operation over the free-air
temperature range of –40°C to 85°C.
