DESCRIPTION  
TPS22921, TPS22922, and TPS22922B are ultra-low  
rON load switches with controlled turn on.  
TPS22921/2/2B contain an ultra-low rON P-channel  
MOSFET that can operate over an input voltage  
range of 0.9 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 TPS22922  
and in TPS22922B, a 120-Ω on-chip load resistor is  
added for output quick discharge when switch is  
turned off. The rise time (slew rate) of the device is  
internally controlled in order to avoid inrush current:  
TPS22921 and TPS22922 feature a 30 µs rise time  
whereas TPS22922B is 200 µs.  
Low Threshold Control Input Enable the use of  
1.2V/1.8V/2.5V/3.3V Logic
