DRV10983EVM: IC will be burnt

Hi Annie,

Can you share the EEPROM settings & customer motor used?

Was the customer driving a motor for 1-2s before the IC burnt?

Thanks,

Matt

Hi Matt,

It burns when he is ready to download the parameters, and the motor is not driven yet.

Thanks,

Annie

Hi Annie,

I would like to visually inspect the board, can you provide a picture? Something might be shorting the power supply. 

Does the device still burn if operating at a lower voltage? Try limiting the current on the power supply that you're using so the device doesn't burn up when he tests this. If the current hits compliance you'll know something is wrong. 

If IC is burnt, does he have extra IC he can solder on?

Thanks,

Michael

Hi Michael,

The IC is also burnt after replacing the IC. The voltage is 24V.

Thanks,

Annie

Hi Michael,

Is there any suggestion for this case? Or any further information is needed from the customer? Customer uses TI's board.

Thanks,

Annie

Hi Annie,

The team is on holiday due to Memorial Day in the US, and will get back to you tomorrow!

Thanks,

Matt

Hi Annie,

If customer has another IC he can try:

Can you ask customer to try operating at a lower voltage, say 12V? When powering up the EVM please limit the current to 30mA without spinning the motor. You should be able to read the EEPROM settings at this time.

I would like to review those.

Thanks,

Michael

Hi Annie,

Any feedback here?

Thanks,

Matt

Thanks Annie
