BATTERY PROTECTION IC FOR 3-SERIAL-CELL PACK
S-8233B Series
Set S1 to ON, S2 to OFF, V1, V2, and V3 to 3.5 V, and V5 to 0 V under normal condition. Increase V6 from
0 V gradually. The V6 voltage when I6 = 10 µA is DOP'L' voltage (V
Set S1 to OFF, S2 to ON, V1, V2, V3 to 3.5 V, and V5 to V
V7 from 0 V gradually. The V7 voltage when I7 = 10 µA is the DOP'H' voltage (V
Set V1, V2, V3 to 3.5 V and V5 to 0 V under normal condition. Increase V6 from 0 V gradually. The V6
voltage when I1 = 10 µA is the COP'L' voltage (V
Set V1, V2, V3 to 3.5 V under normal condition. 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 over charge detection delay time 1 (t
Set V1, V2, V3 to 3.5 V under normal condition. 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 over discharge detection delay time 1 (t
Set S1 to ON, V1, V2, and V3 to 3.5 V, and V5 to 10.5 V under normal condition. V5/I5 is the internal
resistance between VCC and VMP (R
Set S1 to ON, V1, V2, and V3 to 1.5 V, and V5 to 4.1 V under over discharge condition. (4.5-V5)/I5 is the
internal resistance between VSS and VMP (R
Set V1, V2, V3 to 3.5 V under normal condition. 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 over charge detection delay time 2 (t
Set V1, V2, V3 to 3.5 V under normal condition. 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 over discharge detection delay time 2 (t
Set V1, V2, V3 to 3.5 V and S1 to OFF under normal condition. Increase V5 from 0 V to 0.55 V
immediately (within 10 µs). The time after V5 becomes 0.55 V until DOP goes 'H' is the over current
detection delay time 1 (t
Set V1, V2, V3 to 3.5 V and S1 to OFF under normal condition. Increase V5 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 over current
detection delay time 2 (t
Set V1, V2, V3 to 3.5 V under normal condition. 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 over charge detection delay time 3 (t
Set V1, V2, V3 to 3.5 V under normal condition. 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 over discharge detection delay time 3
(t
Set S1 to ON to inhibit over discharge detection. Set V1, V2, V3 to 4.0 V and increase V5 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 V5 becomes 6.0
V until DOP goes 'H' is the over current detection delay time 3 (t
