4.2 Option 2: Separate VCC and 5-V Supply

Follow the procedure listed below to set up and use the TMAG5124EVM with dual supplies, which allows the full VCC range of the TMAG5124 to be tested:

1. Ensure that the shorting plug on J5 is removed.

2. Connect an external 5-V DC supply voltage to the 5-V connection point. Ensure that the 5-V supply is powered down for now.

3. Connect an external DC supply voltage to the VCC connection point, which sets the voltage to the desired level. Ensure this supply is powered down for now.

4. Connect a wire from "VCC_OUT" on the control board to the "VCC_OUT" port of the TMAG5124 device to be evaluated. Repeat this process for "GND."

5. Power on the supply. The blue "OFF" light turns on. This indicates that the device is turned on, and current is flowing through the loop.

6. Test the TMAG5124EVM as outlined in Section 4.3 below.
