DRV8262-Q1: Question about reverse battery protection circuit in EVM

Part Number: DRV8262-Q1
Other Parts Discussed in Thread: DRV8262, DRV8262EVM

Tool/software:

Dear TI experts,

My customer considers DRV8262-Q1 for their next project.

And they checked EVM, both DRV8262 and DRV8714.

They found that DRV8714 EVM has reverse battery protection circuit.

But there are not any similar circuit in DRV8262 EVM schematic.

And my question is,

- Is there any reason that DRV8714 EVM has reverse battery protection circuit although DRV8262 EVM does not have?

- Is it okay to add same reverse battery protection circuit to DRV8262 EVM if my customer needs it? (in the same position?)

Pleaes check this issue. Thanks.

Best regards,

Chase

    Hi Chase,

    Thank you for your question.

    Typically, only our automotive drivers EVM are built with reverse battery protection onboard. For the DRV8262 we released the industrial product and EVM first, hence it did not have reverse battery protection onboard. Later when the automotive version DRV8262-Q1 product was released we did not create a separate DRV8262-Q1EVM because from an evaluation and functional standpoint the industrial version DRV8262EVM could be used.

    Yes it is okay. I assume the DRV8262-Q1 design would be for a 48 V system. In this case be sure to choose the external components to support those voltage and output current levels. Ideally they should match the absolute maximum ratings of the DRV8262-Q1. Thank you.
