DESCRIPTION

OUT2  
The TPS22960 is a small low-rON dual load switch  
with controlled turn on. The devices contain two  
P-channel MOSFETs that can operate over an input  
voltage range of 1.62 V to 5.5 V. Each switch is  
controlled by an on/off input (ON1 and ON2), which is  
capable of interfacing directly with low-voltage control  
signals. In TPS22960 a 85-Ω on-chip load resistor is  
added for output quick discharge when switch is  
turned off.  
V
OUT1  
The rise time (slew-rate) of the device is internally  
controlled in order to avoid inrush current and can be  
slowed down if needed using the SR pin: TPS22960  
feature a 75 µs rise time with the SR pin tied to  
ground and 660 µs with the SR pin tied to high.  
The TPS22960 is available in a space-saving 8-pin  
µQFN package and in an 8-pin SOT package. It is  
characterized for operation over the free-air  
temperature range of –40°C to 85°C.
