2-Axis Magnetic Sensor Circuit
HMC6042
Advanced Information
The Honeywell HMC6042 is a surface mount multi-chip module designed
for low field magnetic sensing such as low cost compassing and
magnetometry. The HMC6042 includes our state of the art 1042 series
magneto-resistive sensors plus a precision mixed signal ASIC containing
three sensor amplifiers and a compatible set/reset strap driver circuit for 2.4
to 3.6 volt operation. The ASIC plus sensors are surface mount packaged in
www.DataaSh3e.e6t4bUy.co5m.0 by 1.0mm LCC that can be used stand alone for very low cost
2-axis compasses, or with the HMC1041Z to complete the magnetic sensor
portion of a 3-axis, tilt compensated compass. Applications for the
HMC6042 include Consumer Electronic Compassing and Magnetometry.
The HMC6042 utilizes Honeywell’s Anisotropic Magnetoresistive (AMR) technology that provides advantages over other
magnetic sensor technologies. The sensors feature precision in-axis sensitivity and linearity, solid-state construction with
very low cross-axis sensitivity designed to measure both direction and magnitude of Earth’s magnetic fields, from tens of
micro-gauss to 6 gauss. Honeywell’s Magnetic Sensors are among the most sensitive and reliable low-field sensors in the
industry.
Honeywell continues to maintain product excellence and performance by introducing innovative solid-state magnetic
sensor solutions. These are highly reliable, top performance products that are delivered when promised. Honeywell’s
magnetic sensor solutions provide real solutions you can count on.

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.
