(4) Measurement Condition 4, Measurement Circuit 1
Normal operation current consumption, Power-down current consumption, Overdischarge current
consumption
Set V1=3.5 V and V2=0 V under normal condition. The current IDD flowing through VDD pin is the normal
operation consumption current (IOPE).
For products with power-down function
Set V1=V2=1.5 V under overdischarge condition. The current IDD flowing through VDD pin is the
power-down current consumption (IPDN).
For products without power-down function
Set V1=V2=1.5 V under overdischarge condition. The current IDD flowing through VDD pin is the
overdischarge current consumption (IOPED).
(5) Measurement Condition 5, Measurement Circuit 1
Internal resistance between VM and VDD, Internal resistance between VM and VSS
Set V1=1.8 V and V2=0 V under overdischarge condition. Measure current IVM flowing through VM pin.
1.8V/|IVM| gives the internal resistance (RVMD) between VM and VDD.
Set V1=V2=3.5 V under overcurrent condition. Measure current IVM flowing through VM pin. 3.5 V/|IVM|
gives the internal resistance (RVMS) between VM and VSS.
(6) Measurement Condition 6, Measurement Circuit 1
CO pin H resistance, CO pin L resistance
Set V1=3.5 V, V2=0 V and V3=3.0 V under normal condition. Measure current ICO flowing through CO pin.
0.5 V/|ICO| is the CO pin H resistance (RCOH).
Set V1=4.5 V, V2=0 V and V3=0.5 V under overcharge condition. Measure current ICO flowing through CO
pin. 0.5 V/|ICO| is the CO pin L resistance (RCOL).
(7) Measurement Condition 7, Measurement Circuit 1
DO pin H resistance, DO pin L resistance
Set V1=3.5 V, V2=0 V and V4=3.0 V under normal condition. Measure current IDO flowing through DO pin.
0.5V/|IDO| gives the DO pin H resistance (RDOH).
Set V1=1.8 V, V2=0 V and V4=0.5 V under overdischarge condition. Measure current IDO flowing through
DO pin. 0.5 V/|IDO| gives the DO pin L resistance (RDOL).
(8) Measurement Condition 8, Measurement Circuit 1
Overcharge detection delay time, Overdischarge detection delay time
Set V1=3.5 V and V2=0 V under normal condition. Increase V1 gradually to overcharge detection voltage
VCU - 0.2 V and increase V1 to the overcharge detection voltage VCU + 0.2 V momentarily (within 10
s).
The time after V1 becomes the overcharge detection voltage until VCO goes "L" is the overcharge detection
delay time (tCU).
Set V1=3.5 V and V2=0 V under normal condition. Decrease V1 gradually to overdischarge detection
voltage VDL + 0.2 V and decrease V1 to the overdischarge detection voltage VDL - 0.2 V momentarily (within
10
s). The time after V1 becomes the overdischarge detection voltage VDL until VDO goes "L" is the
overdischarge detection delay time (tDL).
