hi, guys
I'm designing a voice coil motor driver with DRV8412, this device require 12V for logic regulators and gate drive circuit; one the H bridge which drive the motor, a PVDD up to 50V DC is supplied, the operating current of the output is about 8-9A. In addition, this driver is controlled by a microcontroller which is powered by 5VDC.
Right now I plan to use two power supply to this board, 12V and 50V; a voltage regulator is used to get 5V for microcontroller from 12V.50V power supply goes directly to the H bridge.
I think I should use polygon pour to make different Ground for these three power. But I don't really know how to do that, can somebody give me some advice or recommend me some books or material?
Another thing about the high current, how can I make the track for that? I used some calculator online which says the thickness of the track should be .075 inch for 10A. Is that all?
