3 Operation

Final assembly of the 3D printed structures will be required to complete EVM setup. This may be done with either HALL-HINGE-EVM or with HALL-ADAPATER-EVM.

The following steps walk through the procedure to evaluate TMAG5231 with the HALL-HINGE-EVM. If desired, the 3D assembly may be downloaded, edited and reprinted as needed from SLYU062.zip.

Figure 3-1 through Figure 3-6 show the components included in this kit.

  1. Locate the HALL-HINGE-EVM PCBs. TMAG5231 may be evaluated on this PCB with or without the use of the 3D structures. The device may be powered by connecting a voltage source or battery as indicated in Figure 3-7.
    Figure 3-7 Wiring Guide
  2. To evaluate using the 3D structure, insert the snapped off PCB into the SENS093_Sensor.
    Figure 3-8 Install PCB to SENS093_Slider
  3. Slide the SENS093_Sensor into the SENS093_Track as shown in Figure 3-9.

  4. Slide the SENS093_Slider into the SENS093 Arm as shown in Figure 3-10.
    Figure 3-10 Adding SENS093_Slider
  5. Install the B222 into the SENS093_Brakcet with the magnet oriented as desired.
    Figure 3-11 Adding Magnet
    1. You can freely adjust the horizontal position of the magnet within the SENS093_Bracket by positioning the magnet manually within the open space. The direction of magnet polarization may also be adjusted freely.
    2. You can adjust the vertical position of the magnet by turning the screw shown in Figure 3-12.
      Figure 3-12 Vertical Adjustment Screw
    3. You can fix the SENS093_Slider position by tightening the set screw shown in Figure 3-13.
      Figure 3-13 Set Screw
  6. Optional: Insert the Protractor on to the Track from bottom as shown in Figure 3-14.
    Figure 3-14 Protractor Installation
    1. Indentations occur at 1° intervals. Larger notches indicate 5° intervals.
      Figure 3-15 Protractor Degree Intervals
    2. The bottom edge of the arm aligns with the protractor to mark for angle measurements as shown in Figure 3-16.

  7. Apply 3.3 V to Vcc (accepts 1.65V - 5.5 V) to power Hall-Hinge-EVM.
  8. Adjust the arm position and observe the output LED. The LED will illuminate when device output is activated by a magnetic field.
