FEATURES  
DESCRIPTION  
The TPS22924D is a small, ultra-low RON load switch  
with controlled turn on. The device contains a N-  
channel MOSFET that can operate over an input  
voltage range of 0.75 V to 3.6 V. An integrated  
charge pump biases the NMOS switch to achieve a  
minimum switch ON resistance. The switch is  
controlled by an on/off input (ON), which is capable of  
interfacing directly with low-voltage control signals.

rON = 18.3 mΩ at VIN = 3.6 V  
rON = 18.5 mΩ at VIN = 2.5 V  
rON = 19.6 mΩ at VIN = 1.8 V  
rON = 19.4 mΩ at VIN = 1.2 V  
rON = 20.3 mΩ at VIN = 1.0 V  
rON = 22.7 mΩ at VIN = 0.75 V  
A 1250-Ω on-chip load resistor is added for output  
quick discharge when the switch is turned off. The  
rise time of the device is internally controlled to avoid  
inrush current. The TPS22924D features a rise time  
of 6200 µs at 3.6 V.

Ultra Small CSP-6 package  
0.9 mm x 1.4 mm, 0.5-mm Pitch  
The TPS22924D is available in an ultra-small space-  
saving 6-pin CSP package and is characterized for  
operation over the free-air temperature range of  
–40ºC to 85ºC.
