Patent ID: 7800365

Claim:
A magnetic detection device comprising: a sensor unit which changes an electrical characteristic in accordance with change in each magnetic field intensity of external magnetic fields in (+) direction and (−) direction opposite the (+) direction; and an integrated circuit which is connected to the sensor unit for generating and outputting a (+) magnetic field detection signal and a (−) magnetic field detection signal based on the change in the electrical characteristic, wherein: the integrated circuit is provided with two output terminals and a mode switch circuit which includes a pair of switch terminals; the mode switch circuit is capable of switching between a 1-output mode for outputting the (+) and (−) magnetic field detection signals from one of the output terminals and a 2-output mode for outputting the (+) magnetic field detection signal from the one of the output terminal and the (−) magnetic field detection signal from the other output terminal, respectively depending on a shortcircuit state or a non-shortcircuit state between the switch terminals; and the shortcircuit state and the non-shortcircuit state are allowed to be externally adjusted.
