BQ27520-G4: Request a Design Review.

Part Number: BQ27520-G4


I attached BQ27520-G4 design file.

Could you review the BQ27520-G4 design file?

Best regards

  • Hello Louis,

    Here are my thoughts:

    • Ferrite bead on Regin? I see no issue with this, but it is different from the example schematic.
    • BAT_GD and BAT_LOW can be left floating if you desire, it depends on what you want to do with them though/if you ever want to change it. 
    • CE is set to a fixed 3.3V? Is the source of that voltage a regulator powered from the battery? Maybe I missed something, but keep in mind that CE must not exceed VREGIN + 0.3V, so in a very discharged battery, that condition may be met depending on how your system works. 

    Otherwise, the schematic looks very standard and matches the EVM/example schematic.
