BATTERY PROTECTION IC FOR 3-SERIAL-CELL PACK
S-8233C Series
Measurement Circuits
(1) Measurement 1 Measurement circuit 1
Set V1, V2, and V3 to 3.5 V under normal condition. Increase V1 from 3.5 V gradually. The V1 voltage
when COP = 'H' is over charge detection voltage 1 (V
CU1
). Decrease V1 gradually. The V1 voltage when
COP = 'L' is over charge release voltage 1 (V
CD1
). Further decrease V1. The V1 voltage when DOP = 'H'
is over discharge voltage 1 (V
DD1
). Increase V1 gradually. The V1 voltage when DOP = 'L' is over
discharge release voltage 1 (V
DU1
).
Remark
The voltage change rate is 150 V/s or less.

(2) Measurement 2 Measurement circuit 1
Set V1, V2, and V3 to 3.5 V under normal condition. Increase V2 from 3.5 V gradually. The V2 voltage
when COP = 'H' is over charge detection voltage 2 (V
CU2
). Decrease V2 gradually. The V2 voltage when
COP = 'L' is over charge release voltage 2 (V
CD2
). Further decrease V2. The V2 voltage when DOP = 'H'
is over discharge voltage 2 (V
DD2
). Increase V2 gradually. The V2 voltage when DOP = 'L' is over
discharge release voltage 2 (V
DU2
).
Remark
The voltage change rate is 150 V/s or less.
(3) Measurement 3 Measurement circuit 1
Set V1, V2, and V3 to 3.5 V under normal condition. Increase V3 from 3.5 V gradually. The V3 voltage
when COP = 'H' is over charge detection voltage 3 (V
CU3
). Decrease V3 gradually. The V3 voltage when
COP = 'L' is over charge release voltage 3 (V
CD3
). Further decrease V3. The V3 voltage when DOP = 'H'
is over discharge voltage 3 (V
DD3
). Increase V3 gradually. The V3 voltage when DOP = 'L' is over
discharge release voltage 3 (V
DU3
).
Remark
The voltage change rate is 150 V/s or less.
(4) Measurement 4 Measurement circuit 2
Set V1, V2, V3 to 3.5 V and V4 to 0 V under normal condition. Increase V4 from 0 V gradually. The V4
voltage when DOP = 'H' and COP = 'H, is over current detection voltage 1 (V
IOV1
).
Set V1, V2, and V3 to 3.5 V and V4 to 0 V under normal condition. Fix the COVT terminal at V
SS
,
increase V4 from 0 V gradually. The V4 voltage when DOP = 'H" and COP = 'H' is over current detection
voltage 2 (V
IOV2
).
Set V1, V2, and V3 to 3.5 V and V4 to 0 V under normal condition. Fix the COVT terminal at V
SS
,
increase V4 gradually from 0 V at 400
μ
s to 2 ms. The V4 voltage when DOP = 'H" and COP = 'H' is over
current detection voltage 3 (V
IOV3
).
(5) Measurement 5 Measurement circuit 3
Set S1 to ON, V1, V2, and V3 to 3.5 V, and V4 to 0 V under normal condition and measure current
consumption. I1 is the normal condition current consumption (I
OPE
), I2, the cell 2 current consumption
(I
CELL2
), and I3, the cell 3 current consumption (I
CELL3
).
Set S1 to ON, V1, V2, and V3 to 1.5 V, and V4 to 4.5 V under over discharge condition. Current
consumption I1 is power-down current consumption (I
PDN
).
(6) Measurement 6 Measurement circuit 3
Set S1 to ON, V1, V2, and V3 to 3.5 V, and V4 to 10.5 V under normal condition. V4/I4 is the internal
resistance between VCC and VMP (R
VCM
).
Set S1 to ON, V1, V2, and V3 to 1.5 V, and V4 to 4.1 V under over discharge condition. (4.5-V4)/I4 is the
internal resistance between VSS and VMP (R
VSM
).
