Active current limiter

摘要

An active current limiter controls the flow of current between a power source and a load. The active current limiter includes a power switch coupled between the power source an the load, a current sensor coupled between the power source and the load to sense the level of current flow through the power switch, and one or more fault detection circuits coupled to the current sensor for sensing one or more current fault conditions between the power source and the load and configured to switch of the power switch when a current fault condition is detected.
