Hi Team,

I'd like to ask you about the schematic design review. The setup conditions are ISET=500mA, ICHG=245mA(0.7C), Battery=Li-Polymer 3.7V@350mAh, TMR=not used. Please check the attachment below and let me know the review result.

Hi Jeffery,

Please see my comments on schematic review below.

-IN pin requires a minimum of 1 uF decoupling capacitor placed near the charger IC. In attached schematic C55 is present at input node, but depending on how close USB type C port is to the charger IC on the PCB design an additional capacitor near BQ24230 input may be necessary.

Beyond the feedback on required capacitor at IN pin the rest of the schematic looks good. Required components are present and I can confirm resistor values are correct to set the setup conditions listed in this thread.

Best Regards,

Garrett
