DESCRIPTION

The MP62130/MP62131 Power Distribution

Switch features internal current limiting to

prevent damage to host devices due to faulty

load

conditions.

The

MP62130/MP62131

Analog switch features 90mΩ on-resistance

and operates from 2.7V to 5.5V input. It is

available with a guaranteed current limit,

making it ideal for load switching applications.

The MP62130/MP62131 has built-in protection

for both over current and increased thermal

stress. For over current, the device will limit the

current by changing to a constant current mode.

As the temperature increases as a result of

short circuit, the device will shut off. The device

will recover once the device temperature

reduces to approx 120

°C.

The MP62130/MP62131 is available in MSOP8

and SOIC8 packages.
