charging conditions, then the following calculations
apply :
Current Control :
R5 = V5 / Ich1 = 0.1 / 0.8 = 0.125
R5 = 125m
V5 = Vref x R3 / (R2 + R3) with R2 + R3 ~ 12k
and Vref = 1.24V
R3 = 1k , R2 = 11.4k
V5 = R4 x Io + R5 x Ich2, therefore, R4 = (V5 - R5
x Ich2) / Io with Io = 1.4mA

R4 = 53.6
Vref = Vl x R15 / (R14 + R15) with Vl = 2.5V and
R14 + R15 ~ 20k
R15 = R14 = 10k
Voltage Control :
Vref = Vh x R6 / (R6 + R7) with Vh = 6.5V and
R6 + R7 ~ 12k
R6 = 2.36k , R7 = 10k
Vref = Vh R17 / (R16 + R17)
R17 = 10k , R16 = 42k
