Contactor, an integrated circuit, a method of interrupting a current flow

An integrated circuit comprising:

• a controller in the form of a programmable processor;
• a magnetic sensor arranged for outputting a sensor signal indicative of a first current in a conductor;
• a shunt interface for sensing a voltage over a shunt resistor connectable to the integrated circuit and for outputting a shunt signal;
• wherein the processor is configured for:
• i) receiving the magnetic sensor signal and the shunt signal;
• ii) comparing at least the magnetic sensor signal and the shunt signal;
• and
• iii) generating an output signal based on the comparison of the magnetic sensor signal and the shunt signal.

An integrated circuit comprising:

• a magnetic sensor arranged for outputting a magnetic sensor signal indicative of a current in a conductor;
• a shunt interface arranged for outputting a shunt signal indicative of the current in the conductor;
• and
• a processing circuit arranged for receiving the magnetic sensor signal and the shunt signal, the processing circuit configured for:
• determining a difference between the magnetic sensor signal and the shunt signal;
• and
• providing an output signal based on the difference between the magnetic sensor signal and the shunt signal.
