DESCRIPTION

The MP6205 Power Distribution Switch features

internal current limiting to prevent damage to host

devices due to faulty load conditions. The MP6205

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 MP6205 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 MP6205 is available in QFN8, MSOP8E,

SOIC8E packages.
