FEATURES  
DESCRIPTION  
The TPS22913 is a small, low rON load switch with  
controlled turn on. The device contains a P-channel  
MOSFET that can operate over an input voltage  
range of 1.4 V to 5.5 V. The switch is controlled by an  
on/off input (ON), which is capable of interfacing  
directly with low-voltage control signals. The  
TPS22913 is active high enable.  
Integrated Single Load Switch  
Ultra Small CSP-4 Package 0.9mm × 0.9mm,  
0.5mm Pitch  
Input Voltage Range: 1.4-V to 5.5-V  
Low ON-Resistance  
rON = 60-mΩ at VIN = 5-V  
rON = 61-mΩ at VIN = 3.3-V  
rON = 74-mΩ at VIN = 1.8-V  
rON = 84-mΩ at VIN = 1.5-V  
The TPS22913 contains  
a 150-Ω on-chip load  
resistor for quick output discharge when the switch is  
turned off. The rise time of the device is internally  
controlled in order to avoid inrush current. The  
TPS22913 family has various slew rate options (see  
Table 1).  
2-A Maximum Continuous Switch Current  
Low Threshold Control Input  
Controlled Slew-rate Options  
Under-Voltage Lock Out  
The TPS22913 device provides circuit breaker  
functionality by latching off the power-switch during  
reverse voltage situations. An internal reverse voltage  
comparator disables the power-switch when the  
output voltage is driven higher than the input (VIN) to  
quickly (10µs typ) stop the flow of current towards the  
input side of the switch. The reverse current  
protection is active when the power switch is enabled  
(ON). Additionally, during under-voltage lockout  
(UVLO), or when the switch is disabled, no reverse  
current can flow as the switch body diode is not  
engaged.
