DESCRIPTION
The TPS20xxC 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 1 A and 2 A.
The TPS20xxC 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.
