DRV8312: DRV8312 broke when connect with MCU

Part Number: DRV8312

Dear team,

Customer found DRV8312 was broken when connect with MCU. Would you kindly review the schematic? Customer wonder if they need to add an isolator between DRV8312 and MCU?

Thanks.

Best regards,

Sammi

  • Sammi,

    Do you know which part of the chip is breaking?

    What triggers the chip damage? Does it occur at power up or motor start?

    Is there any fault or OTW triggered?

    Can the customer provide any scope images of the issue or powerup?

    Regards,

    -Adam
