Layout

The EVAL-M7-HVMOS-INV board consists of two copper PCB layers. The copper thickness is 35 μm and the board
size is 103 mm x 96 mm. The board material is FR4 grade with 1.6 mm thickness. Check Infineon's website or
contact Infineon's technical support team for more detailed information. The Gerber files are available on the
download section of the Infineon homepage. A log-in is required to download this material.
The top layer and bottom layer PCB layout are shown in Figure 17 and Figure 18. For the power board PCB
layout, users should connect the signal ground and power ground at one single point to keep low noise for the
current-feedback sensing. The current-feedback trace should be short and close to ground copper. This can
ensure that less noise is introduced into the current feedback loop. Lower current feedback noise is beneficial
to motor control performance.
