DESCRIPTION

The MP62340-1/MP62341-1 Power Distribution

Switch features internal current limiting to

prevent damage to host devices due to faulty

load conditions. The MP62340-1/MP62341-1

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 MP62340-

1/MP62341-1 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 MP62340-1/MP62341-1 involves discharge

function that provides a resistive discharge path

for the external output capacitor when the part

is disabled.

The MP62340-1/MP62341-1 is available in 8-

pin MSOP package with exposed pad and

SOIC package without exposed pad.
