Other Parts Discussed in Thread: DRV8873, DRV8873-Q1
Hi,
I’m trying to determine the trace widths for my power traces for a motor driver circuit. I'm referencing TIDA-020008 design and I have a few questions:
- In TIDA-020008 layout, how much current can go through reverse protection diode D1? I see that it only has a trace width of 10 mil. Just want give it sufficient trace width.
- What’s the recommended minimum trace width for VBAT or VIN+ traces?
- What’s the recommended minimum trace width for 3.3V traces?
- What's the recommended trace width for signal lines?
My motor driver circuit's application has a motor RMS current of 3.5A and stall current of 9A.
Thanks,
John
