6.0 V immediately (within 1
μ
s) and decrease V1, V2, and V3 to 2.0 V at a time. The time after V5
becomes 6.0 V until DOP goes 'H' is the over current detection delay time 3 (tIOV3).
(13) Measurement 13 Measurement circuit 8
Set S4 to ON, S1, S2, S3, S5, and S6 to OFF, V1, V2, V3 to 3.5 V and V6, V7, and V8 to 0 V under
normal condition. Increase V5 from 0 V gradually. The V5 voltage when I5 = 10
μ
A is the CD1'L'
voltage (CD1(L))
Set S5 to ON, S1, S2, S3, S4, and S6 to OFF, V1, V2, and V3 to 3.5 V and V5, V7, and V8 to 0 V under
normal condition. Increase V6 from 0 V gradually. The V6 voltage when I6 = 10
μ
A is the CD2'L'
voltage (VCD2(L)).
Set S6 to ON, S1, S2, S3, S4, and S5 to OFF, V1, V2, and V3 to 3.5 V and V5, V6, and V8 to 0 V under
normal condition. Increase V7 from 0 V gradually. The V7 voltage when I7 = 10
μ
A is the CD3'L'
voltage (VCD3(L)).
Set S1 to ON, S2, S3, S4, S5, and S6 to OFF, V1 to 4.5 V, V2 and V3 to 3.5 V and V5, V6, and V7 to 0
V under over charge condition. Increase V8 from 0 V gradually. The V8 voltage when I8 = 0.1
μ
A is the
CD1'H' voltage (VCD1(H)).
Set S2 to ON, S1, S3, S4, S5, and S6 to OFF, V2 to 4.5 V, V1 and V3 to 3.5 V and V5, V6, and V7 to 0
V under over charge condition. Increase V4 from 0 V gradually. The V4 voltage when I1 = 0.1
μ
A is the
CD2'H' voltage (VCD2(H)).
Set S3 to ON, S1, S2, S4, S5, and S6 to OFF, V3 to 4.5 V, V1 and V2 to 3.5 V and V5, V6, and V7 to 0
V under over charge condition. Increase V8 from 0 V gradually. The V8 voltage when I8 = 0.1
μ
A is the
CD3'H' voltage (VCD3(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 (ICOL).
(15) Measurement 15 Measurement circuit 10
Set V1, V2, and V3 to 0 V, and V5 to 2 V, and decrease V5 gradually. The V5 voltage when COP = 'H'
(VSS + 0.3 V or higher) is the 0V charge start voltage (V0CHAR).
(16) Measurement 16 Measurement circuit 1 ( Measurement will be changed by the CTL logic! )
If the CTL logic is
“
normal
”
Set V1, V2, and V3 to 3.5 V, and V4 to 0 V, and increase V4 gradually. The V4 voltage when COP = 'H'
(VSS + 0.3 V or higher) and DOP = 'H' (VSS + 0.3 V or higher) is the CTL
’
H
’
input voltage {VCTL(H)}.
After that decrease V4 gradually. The V4 voltage when COP =
‘
L' (VCC - 0.3 V or lower) and DOP = 'L'
(VCC - 0.3 V or lower) is the CTL
’
L
’
input voltage {VCTL(L)}.
If the CTL logic is
“
reverse
”
Set V1, V2, and V3 to 3.5 V, and V4 to10.5 V, and decrease V4 gradually. The V4 voltage when COP =
'H' (VSS + 0.3 V or higher) and DOP = 'H' (VSS + 0.3 V or higher) is the CTL
’
L
’
input voltage {VCTL(L)}.
After that increase V4 gradually. The V4 voltage when COP =
‘
L' (VCC - 0.3 V or lower) and DOP = 'L'
(VCC - 0.3 V or lower) is the CTL
’
H
’
input voltage {VCTL(H)}.
