    Hi Lawrence,

    I noticed that the FAULT pin has a protection resistor after the pull up to 1.8V. It is better to put the protection resistor closer to the MCU since when FAULT pulls down, the MCU will now see a voltage division and not the expected 1.8V.

    I also noticed that for best EMC performance, the customer is missing the 220nF capacitor from supply to system_GND. 

    Since there is no GND network, system_GND and IC_GND are the same node.

    Thanks,
