2.4 Jumper Information

The DRV8376EVM has a few configurations that can be made with jumpers. Use these sections as a guide on how to make those configurations using jumpers.

Hall Sensors

DRV8376EVM DRV8376EVM Hall Configuration Figure 2-4 DRV8376EVM Hall Configuration

The connections that need to be made to the Hall terminal block are shown in Figure 2-4. The figure also shows how to configure the hall power. For externally supplied hall power, supply the power to TP12 and make sure there is a jumper where the blue rectangle is, as seen in the figure above.
