Hi,

If FG interface is not used in DRV8308, then the following connections are good enough?

Hi Sadashiva,

Thanks for posting to the MD forum!

If not using the FG interface, you can leave the FGFB, FGINN_TACH, and FGINP as floating.

I used the schematic from TIDA-00197 as a reference: https://www.ti.com/lit/df/tidr561/tidr561.pdf?ts=1594044032103&ref_url=https%253A%252F%252Fwww.ti.com%252Ftool%252FTIDA-00197
