1.1 Features

This EVM includes the following features:

  • Supports multiple options for setting BOP

    • GUI-controlled DAC (requires Sensor Controller Board for initialization)

      • Sets voltage on TMAG5328 ADJ pin to create desired BOP

      • Enables dynamically changing BOP by changing DAC output voltage

      • Nonvolatile memory on DAC can store DAC output voltage setting to support future operation without GUI or Sensor Controller Board

    • Potentiometer

      • Sets resistance on TMAG5328 ADJ pin to create desired BOP

      • Enables dynamically changing BOP by adjusting potentiometer position

    • Resistor footprint for creating a static BOP

    • External voltage supply

  • LED on TMAG5328 output for visual inspection of switch’s output state

  • Flexible TMAG5328 power supply options

    • 3.3-V rail from Sensor Controller Board: Enables evaluation without external power supply

    • External power supply: TMAG5328 powered independently from Sensor Controller Board, which enables testing the TMAG5328 at other voltages than 3.3 V

  • 3D-printed magnetic attachment included in kit for facilitating magnetic testing
