Hello -
I have custom hardware consisting primarily of a TMS320F28027F and a DRV8305 (using InstaSPIN-FOC).
My board is operational, but the DRV8305 runs quite hot. Even at low-current motor operation I am seeing average temps around 140 F (60 C). I know that this is within spec, but just wanted to make sure this is typical.
The Power PAD is connected to a ground pour by about 8 small (13 mil) vias. Running 45Khz PWM.
Any help is appreciated.
Thanks,
