DESCRIPTION

The MP62260-1/MP62261-1 Power Distribution

Switch features internal current limiting to

prevent damage to host devices due to faulty

load conditions. The MP62260-1/MP62261-1

operates from 2.7V to 5.5V nominal input

to handle up to 2A continuous load with a 3A

typical current limit. The MP62260-1/MP62261-

1 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 MP62260-1/MP62261-1 involves output

discharge function that provides a resistive

discharge path for the external output capacitor

when the part is disabled.

The MP62260-1/MP62261-1 is available in

SOIC8 package.
