DRV8323: How to select the right sink and source current

Cherry Zhou

Part Number: DRV8323

Hi team,

The DRV8232 can be configured for 10mA to 1A peak source and 20mA to 2A peak sink currents, how to select the appropriate source/sink configuration? And is it related to any parameters of external MOSFETs? Is there a formula for that?

Could you help check this case case? Thanks.

Best Regards,

Cherry

Hi Cherry,

The sink/source current configuration is set using the IDRIVE pin/register bits.

To find the correct source/sink configuration, and the equations involved in doing so, please refer to this E2E FAQ.

For a more in depth explanation on finding the correct sink/source configuration please refer to this app note.

Best Regards,

Joshua
