DESCRIPTION

The

MP6231/MP6232

Power

Distribution

Switch features internal current limiting to

prevent damage to host devices due to faulty

load conditions. The MP6231/MP6232 analog

switch has 85mΩ on-resistance and operates

from 2.7V to 5.5V input. It is available with

guaranteed current limits, making it ideal for

load

switching

applications.

The

MP6231/MP6232 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, then the device will shut off. The

device will recover once the device temperature

reduces to approx 120

°C.

The MP6231/MP6232 is available in 8-pin

MSOP, SOIC package with exposed pad and 8-

pin SOIC w/o exposed pad.
