Coreless current sensor for motor vehicle, has Hall-integrated circuit with temperature measuring part to determine environmental temperature, where measuring signal and temperature signal are output outwards over connecting terminals

摘要

The sensor has a Hall-integrated circuit (IC) (43) with a magnetism detecting part (438) to determine a value of a magnetic field and a temperature measuring part (436) to determine an environmental temperature. The circuit has a temperature compensation part (437) to correct an error of the part (438), where the error is caused based on the temperature. A measuring signal of the part (438) that is corrected based on the error and a temperature signal that is determined by the part (436) are output outwards over connecting terminals.
