I'm evaluating several TI fuel gauges for a mobile product, particularly the BQ27542 (a pack-side gauge) and BQ27510 (a system-side gauge). We will use the gauge in a system-side configuration. Our battery is user-replaceable, and has no protection circuitry, so we also have a battery protection IC on our PCB.
My question is, what would happen if we used a pack-side gauge in a system-side configuration? What's the difference between the two?
I saw this post on the forum that asks a similar question, but the answer for that party was to use a different gauge, so the question wasn't directly answered.
Thank you,
