Set S1 = ON, S2 = OFF, V1 = V2 = 3.6 V and V3 = 0 V under normal status. Increase V4 from 0 V
gradually. The V4 voltage when I1 = 10 μA is the CO “H” voltage (V
Set S1 = OFF, S2 = ON, V1 = V2 = 4.7, V3 = 0 V, and V5 = 9.4 V under overcharge status. (V5) / I2 is
the CO pin internal resistance (RCO(L)).
