BQ25303J: PCB layout Design Review

Hi Andres,

Schematic Review:

1. Confirming 4.2 charge voltage limit and 2 A charge current.

Layout Review:

1. I would try and see if you can move the PMID capacitor closer in. This could involve maybe moving the BTST capacitor a little further to the right.

2. It is important to place the REGN capacitor as close as possible to the pin. The via for the STAT pin is lower in priority than the REGN capacitor placement.

Hi Andy,

You can also move VBUS cap closer to the IC. No need to have all that extra pour on PMID to the left of the cap.

Yes indeed!

Hi Andres,

The only room for improvement is to use smaller capacitors as you are able. Please compare with the BMS005 REV A. The size of some of the capacitors seems larger than what we use on our EVM.
