| Abstract: | This paper briefly introduced the working principle of close-loop hall current sensor,and proposed a over current protection circuit which can clamp the output current to the setting value when the primary current of hall current sensor is over load. This circuit can protect the sensor even the primary current three or more times over load,which is verified by experimental data. |
