Hello Wilson,
Thank you very much for your quick reply.
As I understood about the specs. of the driver, it should work properly even if it is supplied with 4.4V.
I did try with 6V, and my motor seems to be working quite well. Only thing is nFault keeps sending warings by pulses, I just wonder if I could disable this specific warning detection somehow?
Otherwise I will boost it up to 8V, but do you have some recommended DC-DC solutions? The battery output voltage will be 3.7V or 7.2V, and the motor stall current is 3.34A.
Many thanks in advance.
Best regards
Weinan
