DESCRIPTION

The MP62150/MP62151 Power Distribution Switch

features internal current limiting to prevent damage

to host devices due to faulty load conditions. The

MP62150/MP62151 operates from a 2.7V or 5.5V

nominal input voltage and includes 85mΩ Power

MOSFET to handle up to 1.5A continuous load with

a 2.3A typical current limit. The MP62150/MP62151

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 MP62150/MP62151 is available in MSOP8

package with exposed pad.
