DESCRIPTION

The

MP6211-3/MP6212-3

single-channel

Power Distribution Switch features internal

current limiting to prevent damage to host

devices due to faulty load conditions. The

MP6211-3/MP6212-3 Analog switch has 95mΩ

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 MP6211-3/MP6212-3 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 FLAG output of MP6211-3/MP6212-3 will

report a fail mode (low level) when over current

or over temperature is encountered. The FLAG

will not change state when the input UVLO is

triggered.

The MP6211-3/MP6212-3 is available in 8-Pin

MSOP package with exposed pad and 8-Pin

SOIC8 package with exposed pad.
