Set S4 to ON, S1, S2, S3, S5, and S6 to OFF, V1, V2, V3 to 3.5 V ,and V4, V6, to 0 V under normal
condition. Increase V5 from 0 V gradually. The V5 voltage when I5 = 10 µA is the CSO'L' voltage
(V_CSO(L))
Set S5 to ON, S1, S2, S3, S4, and S6 to OFF, V1, V2, and V3 to 3.5 V and V4, V6 to 0 V under normal
condition. Increase V5 from 0 V gradually. The V5 voltage when I5 = 10 µA is the ISO'L' voltage (V_ISO(L)).
Set S6 to ON, S1, S2, S3, S4, and S5 to OFF, V1, V2, and V3 to 3.5 V and V4, V6 to 0 V under normal
condition. Increase V5 from 0 V gradually. The V5 voltage when I5 = 10 µA is the DSO'L' voltage
(V_DSO(L)).
Set S1 to ON, S2, S3, S4,S5, and S6 to OFF, V1 to 4.5V, V2, and V3 to 3.5 V, V5, and V6 to 0 V under
over voltage condition. Increase V4 from 0 V gradually. The V4 voltage when I4 = 0.1 µA is the CSO'H'
voltage (V_CSO(H)).
Set S2 to ON, S1, S3, S4, S5, and S6 to OFF, V1, V2 and V3 to 3.5 V, V5 to 0 V, V6 to V_IOV2+0.1V under
over current condition. Increase V4 from 0 V gradually. The V4 voltage when I4 = 0.1 µA is the ISO'H'
voltage (V_ISO(H)).
Set S3 to ON, S1, S2, S4, S5, and S6 to OFF, V1 to 1.9V,V2 and V3 to 3.5 V, V5 and V6 to 0 V under
over discharge condition. Increase V4 from 0 V gradually. The V4 voltage when I4 = 0.1 µA is the
DSO'H' voltage (V_DSO(H)).
(14) Measurement 14 Measurement circuit 9
Set V1, V2, and V3 to 4.5 V under over charge condition. The current I1 flowing to COP terminal is COP
OFF LEAK current (I_COL).
(15) Measurement 15 Measurement circuit 10
Set V1, V2, and V3 to 0 V, and V8 to 2 V, and decrease V8 gradually. The V8 voltage when COP = 'H'
(V_SS + 0.1 V or higher) is the 0 V charge start voltage (V_0CHAR).
