Hello,
I have a few hardware and software questions related to the DRV8308.
1. If I am not using the FG feature of the device, what is the proper connection for the FG pins (FGFB, FGINN_TACH, and FGINP)?
2. If I am using the device in "open loop PWM" mode, does the device implement the "Auto-advance" feature ? Or is "auto-advance" only applicable for closed-loop speed control mode?
3. In open loop PWM mode, I need more guidance on choosing the register settings for the following registers:
- SPDREVS
- MINSPD
- SPEEDTH
- HALLRST
- AUTOADV
- DTIME
- AA_SETPT
- OCPDEG
- OCPTH
Sorry I know this is a lot of info. Please let me know if you can help me select the best values for these registers.
Thanks,
Mohan
