Basic Device Operation
The HMC1051 and HMC1052 are single-axis and two-axis linear magnetic sensors designed as a Wheatstone
bridges formed by a magnetoresistive metal film. With the power supply applied to the bridge, the sensors converts
any incident magnetic field in the sensitive direction to a balanced voltage output. The magnetoresistive sensors are
made of a nickel-iron (Permalloy) thin-film deposited on a silicon wafer in pattern of resistive strips. In the presence of
a magnetic field, a change in the bridge resistive elements causes a corresponding change in voltage across the
bridge outputs.
In addition to the bridge circuits, the sensors each have two on-chip magnetically coupled straps; the Offset Strap and
the Set/Reset Strap. The patented straps eliminate the need for external coils surrounding the bridge elements. The
offset strap (available on bare die only) allows for several modes of operation when a direct current is driven through
it. These modes are: 1) Subtraction of an unwanted magnetic field, 2) Zero-ing of the bridge offset voltage, 3) Closed
loop field cancellation, and 4) Auto-calibration of bridge gain. The set/reset strap can be pulsed with high currents for
the following benefits: 1) Enable the sensor to perform high sensitivity measurements, 2) Flip the polarity of the bridge
output voltage, and 3) Periodically used to improve linearity, lower cross-axis effects, and temperature effects.
Application Notes
Low Cost 2-Axis Compass
Very high precision measurements can be made using the HMC1051 and HMC1052 sensors when interfaced with
low noise amplifiers and 12 to 16-bit Analog-to-Digital (A/D) converters. For lower resolution (1°) or low cost compass
applications, 8 or 10-bit A/D converters may be used with general purpose operational amplifiers. Figure 1 shows a
typical 2-axis compassing application using readily available off-the-shelf components.
The basic principle of two-axis compassing is to orient the sensor bridge element horizontal to the ground
(perpendicular to the gravitational field) and to measure the X and Y analog voltages. With the amplified sensor bridge
voltages near-simultaneously converted (measured) to their digital equivalents, the arc-tangent Y/X can be computed
to derive the heading information. See the application notes on compassing at Honeywell Magnetic Sensors website
(www.magneticsensors.com) for basic principles and detailed application information.
