The Future of Analog IC Technology

MP62055

3.3V/5V, Single-Channel 500mA

Current-Limited Power Distribution Switch

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.
