DESCRIPTION

The MP62055 Power Distribution Switch features internal current limiting to prevent damage to host devices due to faulty load conditions. The MP62055 analog switch features 115mΩ on-resistance and operates from 2.7V to 5.5V input. It is available with a guaranteed current limit, making it ideal for load switching applications. The MP62055 has builtin 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, the device will shut off. The device will recover once the device temperature reduces to approx 120°C.

The MP62055 is available in TSOT23-5 package.
