BASIC DEVICE OPERATION
The Honeywell HMC6042 magnetoresistive sensor circuit is a pair of sensor and analog support circuits to measure
magnetic fields. With power supply applied, the sensor converts any incident magnetic field in the sensitive axis direction
to a differential voltage output. In addition to the bridge circuit, the sensors have two on-chip magnetically coupled straps;
the offset strap and the set/reset strap. These straps are Honeywell patented features for incident field adjustment and
magnetic domain alignment; and eliminate the need for external coils positioned around the sensors.
The magnetoresistive sensors are made of a nickel-iron (Permalloy) thin-film deposited on a silicon wafer and patterned
as a resistive strip element. In the presence of a magnetic field, a change in the bridge resistive elements causes a
corresponding change in voltage across the bridge outputs.
