APPLICATION CIRCUITS
The following are typical application circuits using the HMC100x and HMC102x sensors.
TWO AXIS COMPASS OR MAGNETOMETER
Figure 5 shows the typical schematic diagram.
Figure 5 2-Axis Compass or Magnetometer
From Figure 5, the typical power supplied for VDD is nominally 5 volts, with about 8 volts for the set/reset strap supply
(VSR). A pair of complementary power MOSFETs provides the electronic switch functions, driving the set/reset minus
pins with the set/reset plus pins returned to the MOSFET ground. The MOSFETs are driven by typical 5 volt logic with
normally high levels expected when not pulsing. Each logic transition creates a very high current pulse, as high-to-low
transitions turn-on the P-channel FET while turning-off the N-channel FET. This transfers some of the energy from the
10uf reservoir capacitor to the pair of 0.47uf capacitors while providing a positive pulse. A negative pulse is performed on
the low-to-high logic transition as the P-channel FET is turned off and the N-channel FET is turned on. Then the energy
from the pair of 0.47uf capacitors is discharged through the set/reset straps and the N -channel MOSFET. Ceramic
capacitors with a low-ESR characteristic are required for best pulse performance.
Since the sensor output difference voltage is amplified by low cost operational amplifiers with a low supply voltage feature
(LMV324N), the amplifier requires a half supply voltage reference (VREF). This reference voltage is formed via a buffered
rail-splitter circuit, using a spare op-amp and resistors. The 1 nano-farad capacitors are used to bandwidth limit the
sensor, and to suppress interference. The resistors around the op-amp are chosen for earths 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 to be 4 to 10 times larger than the sensor bridge resistance elements (HMC1002) at 850 ohms. The
