Abstract
A magnetic sensor integrated circuit is provided, which includes: a magnetic sensing element to detect change in an external magnetic field to output a magnetic field sensing signal; a signal processor to process the magnetic field sensing signal and output a magnetic field detection signal; and a current source generator to output a constant current to the magnetic sensing element. The constant current is not influenced by a temperature.
