BQ51050B: issues about NTC thermistor, Ibulk, %Ibulk and schematic

$

Part Number:BQ51050B

Hi!

There are specifications that I would achieve.

1. Temperature sensor// I want to get a similar curve (Temperature vs Vtsb percent) as Figure 30

R13: 200R, R3: 9.76MR (values are from e2e.ti.com/support/power-management/f/196/t/665040?tisearch=e2e-sitesearch&keymatch=bq51050B)

NTC Resistor (Ro: 10k and 3380K) same as ERT-JZEG103JA 

The excel calculator doesn't work in my computer

And I am still not sure how to connect NTC thermistor to my battery or battery pack.

Any recommendations?

 

2. Ibulk = 1.5A

Ibulk - Kilim/Rilim = 314(given) / 209

Rilim = 210

So, R5 = 100R, R6 = 110

3. %Ibulk = 100(%)

%Ibulk = Rterm / Kterm = 24000/240(given) = 100(%)

So, Rterm =24k

 4. Any configuration wrong from my schematic

C1 and C2 values are not decided yet because I am still not sure what coil would be best.

Could you recommend any coil that suits well?

Thanks for reading!
