1A loading, 4.5-5.5V, 86mΩ USB power switch, active-high, reverse blocking

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 from

0.5A to 2A.

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 5V supply to provide regulated power when the output is

shorted. The power-switch rise and fall times are controlled to minimize current

surges during turnon and turnoff.
