Arrow indicates direction of applied field that generates a positive output voltage after a SET pulse.
BASIC DEVICE OPERATION
The Honeywell HMC100x and HMC102x Anisotropic Magneto-Resistive (AMR) sensors are simple resistive Wheatstone
bridges to measure magnetic fields and only require a supply voltage for the measurement. With power supply applied to
the bridges, the sensors convert any incident magnetic field in the sensitive axis directions to a differential voltage outputs.
In addition to the bridge circuits, each sensor has 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.
