Texas Instruments TMAG5328, User Manual, Page: 22 / 36

When the screw is rotated clockwise inside the base, the magnet gets closer to the TMAG5328, thereby
increasing the sensed magnetic flux density. If the screw is turned counterclockwise within the base, the screw
increases its distance with respect to the TMAG5328, which decreases the sensed magnetic flux density.
To use this module with the TMAG5328EVM, perform the following steps:
1. Connect the base of the module to the TMAG5328EVM (see Figure 5-22 ).
Figure 5-22. Base Connected to TMAG5328EVM
2. Place the screw at the top of the base (see Figure 5-23 ). As the screw is brought near the top of the base,
the sensed magnetic flux density will approach around 2 mT.

3. When the screw is at the top of the base, turn the screw clockwise to bring screw and its embedded magnet
closer to the TMAG5328. After the screw is turned clockwise, the TMAG5328 OUT pin will be asserted
low when the sensed magnetic flux density becomes greater than the set B
