DRV8106-Q1: Can I depop HS FET and use as a LS driver?

David Shumate

Part Number: DRV8106-Q1

Hi Team,

My customer is interested in using the DRV8106 as just a lowside driver. Will the part allow us to remove the highside FET (or replace with a diode or resistor) and use as just a lowside driver?

If so, can you clarify what we would need to adjust in hardware/register settings to achieve this?

Best,

David

    Hi,

    Thank you for your question.DRV8106-Q1 can be used as lowside driver. High side FET can be removed.

    - Recommend not turning on high side gate driver. Therefore stay upper 2 states only.

    - Recommend to have external diode. Either "solenoid load" or "resistive load with long wiring", we need discharge path for the energy in inductor.

    regards
