Hi,
Looking at this motor it appears that the motor requires a much higher current that DRV10975 can support.
You could look at a device like DRV8304, however, it will require external FETs and a MCU to provide the control signals for DRV8304. …
Hello, Thank you for posting to the MD forum!
If you're looking for a sensored gate driver IC with good cost performance and 1x PWM input for a 12-V motor, the DRV8306 is the best choice. It includes overcurrent protection, supports up to 38-V, tacho…
Hi Cole,
Thank you for your supporting.
>what was the motor doing right before the slow down? Was a spinning at a constant rate and then it randomly or periodically slowed down?
PWM=80% operation, then it randomly slowed down. however the time…
Hello Mark,
Is this the same question: https://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1030989/drv8304-drv8304 ?
Thanks,
Matt

Sorry I have to come back on this thread that was locked now, due to me taking long. But I need it again…
Hi Christian,
You are correct; I missed the DRV8304 and the DRV8305. The DRV8304 is in Preview state.
The DRV832x, DRV8304, and DRV8307/8 have what is referred to as 1x PWM mode. The DRV8304 refers to this mode as Single PWM mode. This mode allows…
Hey Colin,
Perfect, thanks for the clarification.
Unfortunately, our Gate Driver + Integrated Control portfolio is lacking a bit (as of 2020).
There are plenty of DRV83x devices with a simple trapezoidal algorithm which can be implemented using…
Syuhei,
The input pins of the DRV8304 can handle 5V input but you will need to change some things on the EVM:
The IDRIVE and VDS pins are expecting voltage dividers based on DVDD (3.3V) so you would need to scale these resistors appropriately if…
I am looking into the details of the DRV8304 Booster Pack to get a better answer for you. In the mean time, did you change any of the HAL drivers for the DRV8304 from the DRV8301 implementation? I'm assuming that you haven't changed the gain setting from…
