DESCRIPTION

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.
