Part Number: BQ35100EVM-795
Other Parts Discussed in Thread: BQSTUDIO

Hello,

I'm currently reading a negative current on the bq35100evm with a powers supply and 8 ohm load connect. The documentation (Technical Reference Manual) appears to indicate positive current is discharge.

So what is it? I think the documentation is wrong-Can someone (someone that's actually powered on the device and fiddled with it or someone that works at TI that can get the answer) confirm? Again I think the documentation is wrong here.

Hello,

Yes, discharge current is a negative current. We will put a note in to get the Technical Reference Manual changed,

Thank you.

Additionally, I'd note Richard that the cc gain and cc delta in the Technical Reference Manual Data Flash Table (Table 13-1), show a range of ONLY POSITIVE values, but upon reading bqstudio they are negative.

So the range listed in the TRM is wrong or bqstudio is displaying those values incorrectly.

Best,

Craig
