DESCRIPTION  
Low Control Input Thresholds Enable Use of  
1.2-V/1.8-V/2.5-V/3.3-V Logic  
TPS22906 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-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.
