    Hi Lawrence,

    This schematic looks good. I only have minor changes to recommend. Let me know if there are any questions or concerns regarding the design. See my notes below.

    • INH pin appears connected to MCU. INH IS A VSUP LEVEL OUTPUT. Ensure proper level shifting is done before routing battery-level signal to the MCU.
    • Decoupling capacitors included and valued appropriately.
      • Recommend moving VSUP capacitor (C6007) to IC-side of limiting resistor (R6005).
    • Split capacitor included and valued appropriately.
    • No bus capacitors included - no issue.
    • TVS diode included - ensure placement close to connector and along signal path.
    • Termination resistors included correctly and valued appropriately.
    • CMC placed nominally between transceiver and termination.
    • All pull-up / series resistances are acceptable.
      • nSTB biased to 3V3. This will not bias the device to its lowest power state. Consider a bias to GND.

    Regards,
    Eric Schott
