The MP62351 Power Distribution Switch features internal current limiting to prevent damage to host devices due to faulty load conditions. The MP62351 analog switch has 85mΩ on-resistance and operates from 2.7V to 5.5V input. It is available with guaranteed current limits, making it ideal for load switching applications. The MP62351 has built-in protection for both over current and increased thermal stress. For over current, the device will limit the current by changing to a constant current mode.
As the temperature increases as a result of short circuit, then the device will shut off. The device will recover once the device temperature reduces to approx 120°C.
The MP62351 included a discharge function that provides a resistive discharge path for the external output capacitor when the part is disabled.
