Set S1 to ON, S2 to OFF, V1, V2, and V3 to 3.5 V, and V4 to 0 V under normal status. Increase V5 from
0 V gradually. The V5 voltage when I1 = 10 μA is DOP'L' voltage (V
Set S1 to OFF, S2 to ON, V1, V2, V3 to 3.5 V, and V4 to V
V6 from 0 V gradually. The V6 voltage when I2 = 10 μA is the DOP'H' voltage (V
Set V1, V2, V3 to 3.5 V and V4 to 0 V under normal status. Increase V5 from 0 V gradually. The V5
voltage when I1 = 10 μA is the COP'L' voltage (V
Set V1, V2, V3 to 3.5 V under normal status. Increase V1 from 3.5 V to 4.5 V immediately (within 10 μs).
The time after V1 becomes 4.5 V until COP goes 'H' is the overcharge detection delay time 1 (t
Set V1, V2, V3 to 3.5 V under normal status. Decrease V1 from 3.5 V to 1.9 V immediately (within 10 μs).
The time after V1 becomes 1.9 V until DOP goes 'H' is the overdischarge detection delay time 1 (t
Set V1, V2, V3 to 3.5 V under normal status. Increase V2 from 3.5 V to 4.5 V immediately (within 10 μs).
The time after V2 becomes 4.5 V until COP goes 'H' is the overcharge detection delay time 2 (t
Set V1, V2, V3 to 3.5 V under normal status. Decrease V2 from 3.5 V to 1.9 V immediately (within 10 μs).
The time after V2 becomes 1.9 V until DOP goes 'H' is the overdischarge detection delay time 2 (t
Set V1, V2, V3 to 3.5 V under normal status. Increase V3 from 3.5 V to 4.5 V immediately (within 10 μs).
The time after V3 becomes 4.5 V until COP goes 'H' is the overcharge detection delay time 3 (t
Set V1, V2, V3 to 3.5 V under normal status. Decrease V3 from 3.5 V to 1.9 V immediately (within 10 μs).
The time after V3 becomes 1.9 V until DOP goes 'H' is the overdischarge detection delay time 3 (t
Set V1, V2, V3 to 3.5 V and S1 to OFF under normal status. Increase V4 from 0 V to 0.55 V immediately
(within 10 μs). The time after V4 becomes 0.55 V until DOP goes 'H' is the overcurrent detection delay
time 1 (t
Set V1, V2, V3 to 3.5 V and S1 to OFF under normal status. Increase V4 from 0 V to 0.75 V immediately
(within 10 μs). The time after V4 becomes 0.75 V until DOP goes 'H' is the overcurrent detection delay
time 2 (t
Set S1 to ON to inhibit overdischarge detection. Set V1, V2, V3 to 4.0 V and increase V4 from 0 V to 6.0
V immediately (within 1 μs) and decrease V1, V2, and V3 to 2.0 V at a time. The time after V4 becomes
6.0 V until DOP goes 'H' is the overcurrent detection delay time 3 (t
