FEATURES  
DESCRIPTION  
The TPS20xxC and TPS20xxC-2 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.

Single Power Switch Family  
Pin for Pin with Existing TI Switch Portfolio  
Rated currents of 0.5 A, 1 A, 1.5 A, 2 A  
±20% Accurate, Fixed, Constant Current Limit  
Fast Over-Current Response – 2 µs  
Deglitched Fault Reporting  
The TPS20xxC and TPS20xxC-2 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.
