Monolithic Power Systems

MP62160/MP62161

3.3V/5V, Single-Channel 2A

Current-Limited Power Distribution Switch

with Output Discharge

DESCRIPTION

The MP62160/MP62161 Power Distribution

Switch features internal current limiting to

prevent damage to host devices due to faulty

load conditions. The MP62160/MP62161

operates from a 3.3V or 5V input voltage and

includes an 85mΩ Power MOSFET to handle

up to 2A continuous load with a 2.8A typical

current limit. The MP62160/MP62161 has built-

in protection for both over current and

increased thermal stress. For over-current

protection (OCP), the device will limit the

current by going into a constant current mode.

When continuous output overload condition

exceeds power dissipation of the package, the

thermal protection will shut the part off. The

device will recover once the device temperature

reduces to approx 120°C.

The MP62160/MP62161 involves a discharge

function that provides a resistive discharge path

for the external output capacitor when the part

is disabled.

The MP62160/MP62161 is available in QFN8E,

MSOP8E and SOIC8 packages.
