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 ...

... Three of these strap resistances are chosen since many users desire 3-axis magnetic field sensing that comes from a pairing of a HMC1001 and a HMC1002. Also this combination of three series straps is also used on the HMC2003 hybrid sensor module and in the HMR2300 Smart Digital Magnetometer. ...

... D1 1N4148 Figure 4 – Higher Voltage Set/Reset Circuit for HMC1001 & HMC1002 The three strap resistances are chosen at 1.8 ohms, or the worst-case high resistance points. Since they require a minimum of 3 amperes peak, the series combination requires at least 16.2 volts circuit Vdd of about 18 volts would about the right level to drive the strap load and allocate for losses in the C1 capacitor ESR and the MOSFET switches X1 and X2. C1’ ...

... The resistors around the op-amp are chosen for earth’s magnetic field strength (about 0.6 gauss) levels and to match with the sensor impedance. The 4.99k-ohm resistors are a bridging impedance that is normally chosen times larger than the sensor bridge resistance elements (HMC1002) at 850 ohms. The www.honeywell.com ...

... As a compass, the two outputs constrain the earth’s magnetic field measurement to horizontal orientations with the Xout and Yout feeding the heading equation of arctan (Yout/Xout) in degrees. The Xout direction of the HMC1002 should be mounted to the forward direction of the product for proper orientation tilt-compensated compass is desired, a third axis could be made from the spare LMV324N amplifier and a HMC1001 sensor ...
