Team,
I am wondering about the tolerances to mount a heatsink on the DRV8432 to get max thermal performance.
http://www.ti.com/lit/ds/symlink/drv8432.pdf
On page 28 of the pdf we get the physical dimensions for the thickness of the part.
Adding up the max tolerances we get 3.6mm + 0.3 mm + 0.15mm = 4.05 mm
Adding up the min tolerances we get 3.1mm + 0.1 mm + 0.15mm = 3.35 mm
0.7 mm tolerance seems kind of big.
I went with a 4 mm standoff and can see daylight between the parts all day long.
The eval uses a 1/8 in spacer (3.17 mm). I would think this would crush a 4.0mm part.
Have you seen this issue and can you get some help suggesting a spacer?
Thanks Team in advance, I appreciate the help here.
