5. CO Pin Resistance “H”
(Test Condition 4, Test Circuit 3)
5. 1 CO pin output logic = Active “H”
The CO pin resistance “H” (RCOH) is the resistance at the CO pin under the set conditions of V1 = 4.5 V, V2 =
0 V, V3 = 4.0 V.
5. 2 CO pin output logic = Active “L”
The CO pin resistance “H” (RCOH) is the resistance at the CO pin under the set conditions of V1 = 3.5 V, V2 =
0 V, V3 = 3.0 V.
6. CO Pin Resistance “L”
(Test Condition 4, Test Circuit 3)
6. 1 CO pin output logic = Active “H”
The CO pin resistance “L” (RCOL) is the resistance at the CO pin under the set conditions of V1 = 3.5 V, V2 =
0 V, V3 = 0.5 V.
6. 2 CO pin output logic = Active “L”
The CO pin resistance “L” (RCOL) is the resistance at the CO pin under the set conditions of V1 = 4.5 V, V2 =
0 V, V3 = 0.5 V.
7. DO Pin Resistance “H”
(Test Condition 5, Test Circuit 3)
The DO pin “H” resistance (RDOH) is the resistance at the DO pin under the set conditions of V1 = 3.5 V, V2 =
0 V, V4 = 3.0 V.
8. DO Pin Resistance “L”
(Test Condition 5, Test Circuit 3)
The DO pin “L” resistance (RDOL) is the resistance at the DO pin under the set conditions of V1 = 1.8 V, V2 =
0 V, V4 = 0.5 V.
9. Overcharge Detection Delay Time
(Test Condition 6, Test Circuit 4)
9. 1 CO pin output logic = Active “H”
The overcharge detection delay time (tCU) is the time needed for VCO to change from “L” to “H” just after the
voltage V1 momentarily increases (within 10 μs) from overcharge detection voltage (VCU) −0.2 V to overcharge
detection voltage (VCU) +0.2 V under the set conditions of V2 = 0 V.
9. 2 CO pin output logic = Active “L”
The overcharge detection delay time (tCU) is the time needed for VCO to change from “H” to “L” just after the
voltage V1 momentarily increases (within 10 μs) from overcharge detection voltage (VCU) −0.2 V to overcharge
detection voltage (VCU) +0.2 V under the set conditions of V2 = 0 V.
10. Overdischarge Detection Delay Time
(Test Condition 6, Test Circuit 4)
The overdischarge detection delay time (tDL) is the time needed for VDO to change from “H” to “L” just after the voltage
V1 momentarily decreases (within 10 μs) from overdischarge detection voltage (VDL) +0.2 V to overdischarge
detection voltage (VDL) −0.2 V under the set condition of V2 = 0 V.
