FEATURES AND BENEFITS Wide Field Range Field range up to ±6 gauss, (earth’s field = 0.5 gauss) Small Package • Designed for 1- and 2-axis to work together to provide 3-axis (x, y, z) sensing
• 1-axis part in an 8-pin SIP or an 8-pin SOIC or a ceramic 8-pin DIP package • 2-axis part in a 16-pin or 20-pin SOIC package
Solid State These small devices reduce board assembly costs, improve reliability and ruggedness com-
pared to mechanical fluxgates.
On-Chip Coils Patented on-chip set/reset straps to reduce effects of temperature drift, non-linearity errors and
loss of signal output due to the presence of high magnetic fields Patented on-chip offset straps for elimination of the effects of hard iron distortion
Cost Effective The sensors were specifically designed to be affordable for high volume OEM applications.

Frequently Asked Questions
How do I achieve a complete 3-axis magnetic sensing configuration?
The system requires using single-axis parts designed to work together to provide the necessary three-axis (x, y, z) measurement.
Which sensor series is best for high volume or cost-sensitive applications?
The HMC1021/1022 series generally offers lower cost, a wider field range, and lower set/reset current compared to the HMC100x series.
What straps are used to mitigate magnetic distortions like hard iron effects?
The patented on-chip offset straps are utilized for eliminating the effects of hard iron distortion from the measurement.
What is the typical output variation needed after a Set pulse when using the HMC102x sensors?
No explicit "typical" post-set variation value is given; however, the Bridge Offset is listed as -10 ± 2.5 to 11.25 mV after a set pulse (Vbridge=5V).
