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