TPS2052CDGN Datasheet PDF - TI

●The TPS2052CDGN is a dual Power Distribution Switch family 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 and 2A. 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 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.

● Accurate ±20% current limit tolerance

● 2µs (typical) Fast overcurrent response

● Deglitched fault reporting (FLTx)
