FEATURES  
DESCRIPTION  
•
Integrated Single-Channel Load Switch  
•
Ultra Small CSP-4 package  
0.9 mm x 0.9 mm, 0.5-mm Pitch, 0.5-mm Thick  
The TPS22934 is a small, ultra low ON-resistance  
(rON) load switch with controlled turn on. The devices  
contain a P-channel MOSFETs that can operate over  
an input voltage range of 1.5 V to 3.6 V.  
•
•
Input Voltage: 1.5 V to 3.6 V  
Ultra-Low ON Resistance  
The switch is controlled by an on/off input (ON),  
which has built in hysteresis (VTH+(typ) = 2.35 V)  
allowing an easy use of TPS22934 in power-rail  
sequencing applications.  
–

–
–
rDS(ON) = 63 mΩ at VIN = 3.6 V  
rDS(ON) = 69 mΩ at VIN = 2.5 V  
rDS(ON) = 78 mΩ at VIN = 1.8 V  
rDS(ON) = 87 mΩ at VIN = 1.5 V  
In TPS22934 a 35-Ω on-chip load resistor is added  
for output quick discharge when switch is turned off.  
•
•
1-A Maximum Continuous Switch Current  
Integrated Hysteresis Enable Input (ON Pin)  
Allows Easy Power Rail Sequencing  
In TPS22934, the rise time of the device is internally  
controlled in order to avoid inrush current. TPS22934  
feature a typical rise time of 26 µs with a 3.6-V input.  
•
•
•
Controlled Slew Rate Option: 26 µs at 3.6 V  
Quick Output Discharge Transistor  
The TPS22934 is available in an ultra-small  
space-saving  
4-pin  
CSP  
package  
and  
is  
ESD Performance Tested Per JESD 22  
characterized for operation over the free-air  
temperature range of –40ºC to 85ºC.
