HMC1001/1002/1021/1022 PACKAGE / PINOUT SPECIFICATIONS 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 ...

HMC1001/1002/1021/1022 These resistive elements are aligned together to have a common sensitive axis (indicated by arrows on the pinouts) that will provide positive voltage change with magnetic fields increasing in the sensitive direction. Because the output only is in proportion ...

HMC1001/1002/1021/1022 For simpler circuits with less critical requirements for noise and accuracy, a single polarity pulse circuit may be employed periodically (all sets or all resets). With these uni-polar pulses, several uni-polar pulses become close in performance to a single ...

HMC1001/1002/1021/1022 SET/RESET STRAP OPERATION The reasons to perform a set or reset on an AMR sensor are recover from a strong external magnetic field that likely has re-magnetized the sensor optimize the magnetic domains for most ...
