Description

The MP62180/MP62181 Power Distribution Switch features internal current limiting to prevent damage to host devices due to faulty load conditions. The MP62180/MP62181 operates from a 3.3V or 5V nominal input voltage and includes an 85mΩ Power MOSFET to handle up to 2A continuous load with a 2.8A typical current limit. The MP62180/MP62181 has built-in protection for both over current and increased thermal stress. For over-current protection (OCP), the device will limit the current by going into a constant current mode. When continuous output overload condition exceeds power dissipation of the package, the thermal protection will shut the part off. The device will recover once the device temperature reduces to approx 120°C. The MP62180/MP62181 is available in QFN8E, MSOP8E and SOIC8 packages.
