FEATURES  
DESCRIPTION  
The TPS20xxC power-distribution switch family is  
intended for applications such as USB where heavy  
capacitive loads and short-circuits are likely to be  
encountered. This family offers multiple devices with  
fixed current-limit thresholds for applications between  
0.5 A and 2 A.

The TPS20xxC family limits the output current to a  
safe level by operating in a constant-current mode  
when the output load exceeds the current-limit  
threshold. This provides a predictable fault current  
under all conditions. The fast overload response time  
eases the burden on the main 5 V supply to provide  
regulated power when the output is shorted. The  
power-switch rise and fall times are controlled to  
minimize current surges during turn-on and turn-off.
