DESCRIPTION

The

MP62055

Power

Distribution

Switch

features internal current limiting to prevent

damage to host devices due to faulty load

conditions.

The

MP62055

analog

switch

features 115mΩ on-resistance and operates

from 2.7V to 5.5V input. It is available with a

guaranteed current limit, making it ideal for load

switching applications. The MP62055 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 MP62055 is available in TSOT23-5

package.
