DESCRIPTION

The MP62170/MP62171 Power Distribution

Switch features internal current limiting to

prevent damage to host devices due to faulty

load

conditions.

The

MP62170/MP62171

analog switch has 75mΩ 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

MP62170/MP62171 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.

MP62170/MP62171 is available in 8-pin MSOP

and SOIC package without exposed pad.
