7. VC pin current
(Test circuit 2)
The VC pin current (IVC) is the current that flows through the VC pin (IVC) under the set conditions of V1 = V2 = 3.5 V,
V3 = 0 V.
8. Current consumption during power-down, current consumption during overdischarge
(Test circuit 2)
8. 1 With power-down function
The current consumption during power-down (IPDN) is the current that flows through the VSS pin (ISS) under the
set conditions of V1 = V2 = 1.5 V, V3 = 3.0 V.
8. 2 Without power-down function
The current consumption during overdischarge (IOPED) is the current that flows through the VSS pin (ISS) under
the set conditions of V1 = V2 = 1.5 V, V3 = 3.0 V.
9. Resistance between VM pin and VDD pin
(Test circuit 3)
RVMD is the resistance between VM pin and VDD pin under the set conditions of V1 = V2 = 1.8 V, V3 = 0 V.
10. Resistance between VM pin and VSS pin
(Test circuit 3)
RVMS is the resistance between VM pin and VSS pin under the set conditions of V1 = V2 = 3.5 V, V3 = 1.0 V.
11. CO pin resistance "H"
(Test circuit 4)
The CO pin resistance "H" (RCOH) is the resistance between VDD pin and CO pin under the set conditions of V1 = V2 =
3.5 V, V3 = 0 V, V4 = 6.5 V.
12. CO pin resistance "L"
(Test circuit 4)
The CO pin resistance "L" (RCOL) is the resistance between VM pin and CO pin under the set conditions of V1 = V2 =
4.7 V, V3 = 0 V, V4 = 0.5 V.
13. DO pin resistance "H"
(Test circuit 4)
The DO pin resistance "H" (RDOH) is the resistance between VDD pin and DO pin under the set conditions of V1 = V2 =
3.5 V, V3 = 0 V, V5 = 6.5 V
14. DO pin resistance "L"
(Test circuit 4)
The DO pin resistance "L" (RDOL) is the resistance between VSS pin and DO pin under the set conditions of V1 = V2 =
1.8 V, V3 = 0 V, V5 = 0.5 V.
15. Overcharge detection delay time
(Test circuit 5)
The overcharge detection delay time (tCU) is the time needed for VCO to go to "L" just after the voltage V1 increases
and exceeds VCU under the set condition of V1 = V2 = 3.5 V, V3 = 0 V.
