The Infineon high precision coreless current sensor is a high precision miniature coreless magnetic current sensor for AC and DC measurements with analogue interface and two fast over-current detection outputs. Infineon well-established and robust monolithic Hall technology enables accurate and highly linear measurement of currents with a full scale up to ±120A. All negative effects commonly known from open loop sensors using flux concentration techniques are avoided. The sensor is equipped with internal self-diagnostic feature. Typical applications are electrical drives and general purpose inverters. The differential measurement principle allows great stray field suppression for operation in harsh environments.
