DRV10983: Store speed value inside EEPROM

Michele Mocellin
Prodigy 90 points
Part Number: DRV10983
Other Parts Discussed in Thread: MCF8316A,

Hi,

It is possible to store speed value inside EEPROM in DRV109xx family to exclude I2C or analog control ?

In order to use DRV109xx in a "stand alone" mode.

Thank you.

    Hello Michele,

    Thanks for your interest in our products and for posting to the MD forum! Unfortunately, this is not a function that is built in to any of our DRV10x devices, but if you care to look at one of our newest integrated drivers, the MCF8316A I believe it is fully capable of a "stand alone" function. 

    I am not too experienced with this device but I believe that you to store a speed profile in the EEPROM settings and have the motor run at the set speed profile at power up. If you care to read more about this device I will link the datasheet here: https://www.ti.com/lit/ds/symlink/mcf8316a.pdf

    I have asked one of the MCF8316A experts regarding this specific function and should be giving this a try in the lab in the next couple of days. So let me know if you have any additional questions!

    Best,

    Isaac

    Hello Michele,

    It looks like it is possible to set up DRV10983 as a stand alone without an MCU. This can be done by applying a constant voltage to the speed pin in analog mode. You wont be able to save the speed needed via EEPROM register but you can use a resistor network to change your analog voltage to obtain the appropriate speed from your system. This has been used by other customers in the past with success, I hope this works for you too. Let me know if you have any additional questions!

    Best,
