Hi Zunuran,

Please see my comments below.

-Let me point out VCC node connected to 'OUT' pin on BQ24075 should be connected to both pins 10 and 11. The schematic only shows pin 10.

-Similarly battery connection needs to be to both pins 2 and 3. The schematic only shows connection to pin 2.

Beyond the comments above I see no critical issues. All required components are present and selected resistors and capacitors are within allowable range for your intended operation.

Best Regards,

Garrett

Thanks for your detailed review. Its actually confusion due to symbol. In PCB pin 10 and 11 are connected together and Pin 2 and 3 are connected together
