Measurement Circuits
Attention!) At the Measurement circuit from 1 to 15.
If the device
’
s CTL logic is
“
normal
”
then set the CTL voltage at VSS (V4=0V).
If the device
’
s CTL logic is
“
reverse
”
then set the CTL voltage at VCC (V4=V1+V2+V3).
(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 (VCU1). Decrease V1 gradually. The V1 voltage
when COP = 'L' is over charge release voltage 1 (VCD1). Further decrease V1. The V1 voltage when
DOP = 'H' is over discharge voltage 1 (VDD1). Increase V1 gradually. The V1 voltage when DOP = 'L'
is over discharge release voltage 1 (VDU1).
(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 (VCU2). Decrease V2 gradually. The V2 voltage
when COP = 'L' is over charge release voltage 2 (VCD2). Further decrease V2. The V2 voltage when
DOP = 'H' is over discharge voltage 2 (VDD2). Increase V2 gradually. The V2 voltage when DOP = 'L'
is over discharge release voltage 2 (VDU2).
(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 (VCU3). Decrease V3 gradually. The V3 voltage
when COP = 'L' is over charge release voltage 3 (VCD3). Further decrease V3. The V3 voltage when
DOP = 'H' is over discharge voltage 3 (VDD3). Increase V3 gradually. The V3 voltage when DOP = 'L'
is over discharge release voltage 3 (VDU3).
Note: The voltage change rate is 150 V/sec or less under measuring conditions 1 to 3.
(4) Measurement 4 Measurement circuit 2
Set V1, V2, V3 to 3.5 V and V5 to 0 V under normal condition. Increase V5 from 0 V gradually. The V5
voltage when DOP = 'H' and COP = 'H, is over current detection voltage 1 (VIOV1).
Set V1, V2, and V3 to 3.5 V and V5 to 0 V under normal condition. Fix the COVT terminal at VSS,
increase V5 from 0 V gradually. The V5 voltage when DOP = 'H" and COP = 'H' is over current
detection voltage 2 (VI0V2).
Set V1, V2, and V3 to 3.5 V and V5 to 0 V under normal condition. Fix the COVT terminal at VSS,
increase V5 gradually from 0 V at 400
μ
s to 2 ms. The V5 voltage when DOP = 'H" and COP = 'H' is
over current detection voltage 3 (VI0V3).
(5) Measurement 5 Measurement circuit 3
Set S1 to ON, V1, V2, and V3 to 3.5 V, and V5 to 0 V under normal condition and measure current
consumption. I1 is the normal condition current consumption (IOPE), I2, the cell 2 current consumption
(ICELL2), and I3, the cell 3 current consumption (ICELL3).
Set S1 to ON, V1, V2, and V3 to 1.5 V, and V5 to 4.5 V under over discharge condition. Current
consumption I1 is power-down current consumption (IPDN).
