Connect the LDO5V output to the DRV5V_x_x inputs. This output initially supplies 5 V for the drivers from the VSYS pin and then switches to using the 5-V buck converter when available for optimal efficiency.
Ensure that none of the control pins are potentially floating.
Include 0-Ω resistors on the DRVH or BOOT pins of the controllers on prototype boards, which allows for slowing the controllers if the system is unable to handle the noise generated by the large switching or if switching voltage is too large because of layout.
Do not connect the V5ANA power input to a different source other than PVINx. A mismatch here causes reference circuits to regulate incorrectly.
Do not supply the V5ANA power input before the VSYS. Reference biasing of the internal FETs may turn on the HS FET passing the input to the output until VSYS is biased.
