    Hi Brian, 

    Thank you for reaching out via E2E. Overall your schematic for BQ25628E looks good as all required components and connections are present. I do have a couple comments below. 

    -If you plan to use /STAT open drain output signal it should be connected to a pullup rail with a 10Kohm resistor similar to how you connect /PG pin to 3V pullup.

    -There is no issue with connecting /CE to host, but please be aware /CE should always be pulled high or low. 

    Best Regards,

    Garrett
