Programing the DRV10975

Other Parts Discussed in Thread: DRV11873, DRV10975

Hi Texas Instruments!

I'm using the DRV10975 in a project were it is to be operated in a stand-alone (similar to how the DRV11873 is operated) mode by programing the spin-up profile of the used motor to the EEPROM on the DRV10975.

I have read the discussions regarding the programing of the EEPROM on this forum and there seems to be a lot of debate about the voltage required to program the EEPROM (higher than the maximum rating of the device).  Could you specify the required voltage and best procedure to program the EEPROM? My PCB layout is the same as for the demoboard for the DRV10975.

Regards,

Niklas

    Hi Niklas,

    When programming the DRV10975, VCC should be at or above 22V. This is higher than the recommended maximum, but less than the absolute maximum VCC voltage. The programming procedure is described in the section 9.3.5 of the datasheet.

    Hi Niklas

    All the tests and tuning are need to be done at target voltage such as 12V. But eeprom is programmed at 24V.

    Best regards,

    Thank you Rick and Wilson for the quick replies!

    I’m trying to program the DRV10975 on my evaluation board through the PC software. When I click “Burn EEPROM” and have increased the supply voltage over 22VDC nothing happens, when I read the EEPROM the default setting are read from the EEPROM. I’m I required to change anything on the evaluation board to be able to program the EEPROM. The PC software works fine while running the motor and changing settings in the registers.

    Regards,
