3 Description
TPS22906 device is an ultra-small, low ON-state
resistance (rON) load switch with controlled turn on.
The device contains a P-channel MOSFET that
operates over an input voltage range of 1.0 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. A 120-on-chip load resistor
is added for output quick discharge when the switch
is turned off. TPS22906 is available in a space-saving
4-terminal WCSP with 0.5-mm pitch (YZV). The
device is characterized for operation over the free-air
temperature range of –40°C to 85°C.
