Hello
My customer have several questions about terms and also usage of BQ34z100-G1.
Would you please let me know?
Q1 RFACTSTEP
RFACTSTEP : We see RFACTSTEP is used to enable resistance update range set by Min/Max Res Factor.
Also,if RFACTSTEP =0, there are no limitation for Res Factor update....
What is the benefit of RFACTSTEP= 1 ?
What is the actual case customer set this to 1? Please let us know the usage.
Q2 QPCCLEAR
I had answer from local FAE that "QPCCLEAR : Default=0, Allows the gauge to reset the Passed Charge that has accumulated
during rest, when discharge starts."
However, what is the actual case that customer should set QPCCLEAR to =1 ?
We want to know the usage.
Q3 Temp Hys
The usage of Temp hys in bq34z100-g1 is same as BQ27510/BQ27520 case?
We see BQ27520_G4 TRM note ( sluua35 )wrote " [Chg Inhibit Temp Low + Temp Hys, Chg Inhibit Temp High–Temp Hys] ".
Q4 Cycle Count
We see two " Cycle Count" in bqStudio.
One is "Configuration" tab, and other is in Gas Gauging tab.
User should setCycle Count in the Configulation tab?
Which is the Cycle Count in the Configulation tab in 0x2C/0x2D?)
Q5 Max Error()
Max Error() : It seems Read only register,but what does this indicate in the the operation in Gas Gaugeing?
I could not understand well in the Table4 page 15 of data sheet.
What is the usage( benefit ) for customer?
Q6 RNSN1,RSNS2,IWAKE
Vth is same '+5mV or -5mV' in case 1,0,1 and 1,1,0.
However what is the difference 1,0,1 and 1,1,0 for another function? Every thig is same?
Q7 BAT resister dividerI
Customer had better use OP amp for BAT pin,, isn't it?
In the app note slua760 shows the second resister 16.5Kohm. But input resistance Zadc is 100Kohm as per datasheet.
Why is the recommendation is between 15K to 25Kohm for second reisiter because input resistance is 100Kohm?
I am sorry such a basic questions..
Best Regards
