3.3V/5V, Single-Channel 0.8A Current-Limited Power Distribution Switch



The MP62071 Power Distribution Switch features internal current limiting to prevent damage to host devices due to faulty load conditions. The MP62071 operates from a 3.3V or 5V nominal input voltage and includes a 90mΩ Power MOSFET to handle up to 0.8A continuous load with a 1.25A typical current limit. The MP62071 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 MP62071 is available in 8-PIN MSOP8E and SOIC8E package with exposed pad.
