DESCRIPTION

The

MP6211/MP6212

single-channel

Power

Distribution Switch features internal current limiting

to prevent damage to host devices due to faulty load

conditions. The MP6211/MP6212 Analog switch has

90mΩ 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

MP6211/MP6212 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 MP6211/MP6212 is available in an 8-PIN

MSOP and SOIC package with exposed pad.
