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.
