BQ25883: Reviewing BQ25883's layout

Hi Mickey,

Here are my comments on the BQ25883 schematic.

1. The absolute maximum sink current for the STAT pin is 6 mA, as shown in Section 7.1 in the datasheet. I don't know the forward voltage drop for your white LED (LED1001), but I suspect that the current limiting resistor must be larger so that the STAT pin current is <6 mA. I suggest increasing R1011 from 220 Ω to a value between 1 kΩ - 10  kΩ.
2. R1013 is not required. We include this resistor on the BQ25883 EVM because measuring the voltage drop across the sense resistor gives us a convenient way to calculate the system current, but you can leave this resistor out of your schematic.

 For future reference, we have a schematic checklist document for the BQ2588x charger family here:

Here are my comments on the PCB layout:

1. Please move inductor L801 to the left, slightly closer to the BQ25883.

2. It looks like there is space to widen the VSYS copper pour.
