NXP Semiconductors KMZ50
The KMZ50 is an extremely sensitive magnetic field sensor, employing the magnetoresistive effect of thin-film permalloy. The sensor contains one magnetoresistive Wheatstone bridge and integrated set/reset conductors. With the integrated set/reset conductor the orientation of sensitivity may be set or changed (flipped).| Part No. | KMZ50 |

● Navigation● Current and earth magnetic field measurement
● Traffic detection.
DESCRIPTION
A short current pulse on this conductor is needed to recover (set) the sensor after exposure to strong disturbing magnetic fields. A negative current pulse will reset the sensor to reversed sensitivity. By use of periodically alternated flipping pulses and a lock-in amplifier, output will become independent of sensor and amplifier offset.
