Hi Team,
Quick question:
We want to allow charging only from Cold=15°C to Hot=45°C.
The circuit looks like; R_lo=20K, R_hi=15K8 and NTC is 10K with B=3435 (Rntc@15°C=14740, Rntc@45°C=4916).
Looking at Equation 1 and 2 on page 26 and it seems that 15°C-45°C range is not achievable with the NTC that has B=3435, it seems that we would need B=3550 or greater.
Is this statement correct or do I have my math wrong?
I would greatly appreciate your confirmation as well as comments or suggestions on this matter.
Regards,
Ramon
