DESCRIPTION

The MP62170/MP62171 Power Distribution Switch features internal current limiting to prevent damage to host devices due to faulty load conditions. The MP62170/MP62171 analog switch has 75mΩ 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 MP62170/MP62171 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.
