DESCRIPTION  
Low Control Input Thresholds Enable Use of  
1.2-V/1.8-V/2.5-V/3.3-V Logic  
TPS22901, TPS22902, and TPS22902B are  
ultra-small, low ON resistance (rON) load switches  
with controlled turn on. The devices contain 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. In  
TPS22902 and in TPS22902B, a 120-Ω on-chip load  
resistor is added for output quick discharge when the  
switch is turned off.

TPS22901, TPS22902, and TPS22902B are available  
in a space-saving 4-terminal WCSP with 0.4-mm  
pitch (YFP). The devices are characterized for  
operation over the free-air temperature range of  
–40°C to 85°C.
