Hello support. 

One of our major customers is asking for reviewing battery charging circuitry using BQ24030. 

Please see the attached schematic & question file.

    Hello Jonathan,
    If the customer is only using USB, they can leave /ACPG floating. I'll suggest adding a 0.1uF capacitor on LDO and AC, 33uF min cap on BAT. You also want to set ISET2 high so the maximum input current in USB mode will be 500mA. Adding a 10nF cap on DPPM will also help delay the short circuit protection for a small amount of time. The thermistor seems to be absent on the TS pin.

    Regards,
    Raheem
