Overview
The NCP380HSN05AAT1G is a high-side power distribution switch produced by onsemi. This device is designed for applications where heavy capacitive loads and short-circuits are likely to be encountered. It features an integrated P-channel MOSFET and is available in a TSOP-5 package. The NCP380HSN05AAT1G limits the output current to a desired level by switching into a constant-current regulation mode when the output load exceeds the current-limit threshold or a short is present. This switch is particularly useful in protecting the input supply voltage from overcurrent, thermal shutdown, and reverse voltage conditions.
