DRV10983EVM: Modification from REV.B

Part Number: DRV10983EVM
Other Parts Discussed in Thread: DRV10983

Hi all

Would you mind if we ask DRV10983EVM?

At first could you refer to the attachement file?



Left side figure shows Rev.B.
Right side figure shows leatest one.

We could not find the document which differences are written on the Web.
-So, what is the difference?
-Why did you modify?(The background of modification)
-Due to the modification, might DRV10983 damage?
As the background of these questions, on right side EVM, when the customer adds 24V, DRV10983 burned and damaged.

Kind regards,

Hirotaka Matsumoto

  • Hi Hirotaka-san,

    Thanks for posting your question in MD forum. Schematic of both boards is the same and we did not make any major changes between the two boards. We need more information to understand why the board got damaged. Did the board get damaged when 24V was applied across Vcc and GND? Was the motor connected and spinning while the board got damaged? Did you check the power supply to ensure there were no voltage spikes? How did you conclude that the board got damaged? Was there a physical damage?

    Regards,

    Vishnu.

    Thank you so much for your reply.
    We confirm VM voltage in case of start-up now.
    However we haven't received the reply from our customer.
    We assume that it depends which there is no the bulk cap on the EVM.

    Kind regards,
