The TPS2051CDBVT is a Power Distribution Switch family 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 0.5 to 2A. 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 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 turn-on and turnoff.
● ±20% Accurate, fixed, constant current limit
● 2µs Fast overcurrent response
● Deglitched fault reporting
● Reverse current blocking
● Built-in soft start
