Hi.

I do not know how to handle VSYS pins.
What is VSYS?

Do you need separation between analog Gnd and digital Gnd?

Please review below our schematic.

Hi Baek

You should have reviewed the reference schematic in the EVM user guide. i have attached it below:

BIN pin should be connected via a 10k resistor to ground if the battery is non-removable.

The srx ought to be connected to the load/charger and not to ground

thanks

Onyx
