DESCRIPTION
TPS22906 is an ultra-small, low ON-state resistance
(r_ON) 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-Ω 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.
