Monolithic Power Systems’ new power distribution switch features internal current limiting to prevent damage to host devices due to faulty load conditions. The MP62055 analog switch features 115 m on-resistance and operates from 2,7 V to 5,5 V input. It is available with a guaranteed current limit, making it ideal for load switching applications.
The MP62055 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, the device will shut off and it will recover once its temperature reduces to approximately 120°C. The IC is available in the TSOT23-5 package.
