7. Current consumption during power-down, current consumption during overdischarge
(Test circuit 3)
7. 1 With power-down function
The current consumption during power-down (I_PDN) is I_DD under the set conditions of V1 = V2 = 1.5 V.
7. 2 Without power-down function
The current consumption during overdischarge (I_OPED) is I_DD under the set conditions of V1 = V2 = 1.5 V.
8. Resistance between VDD pin and VM pin
(Test circuit 3)
R_VMD is the resistance between VDD pin and VM pin under the set conditions of V1 = 1.8 V, V2 = 0 V.
9. Resistance between VM pin and VSS pin (Release condition of discharge overcurrent status "load
disconnection")
(Test circuit 3)
R_VMS is the resistance between VM pin and VSS pin under the set conditions of V1 = 3.4 V, V2 = 1.0 V.
10. CO pin resistance "H"
(Test circuit 4)
The CO pin resistance "H" (R_COH) is the resistance between VDD pin and CO pin under the set conditions of V1 = 3.4 V,
V2 = 0 V, V3 = 3.0 V.
11. CO pin resistance "L"
(Test circuit 4)
The CO pin resistance "L" (R_COL) is the resistance between VM pin and CO pin under the set conditions of V1 = 4.7 V,
V2 = 0 V, V3 = 0.4 V.
12. DO pin resistance "H"
(Test circuit 4)
The DO pin resistance "H" (R_DOH) is the resistance between VDD pin and DO pin under the set conditions of V1 = 3.4 V,
V2 = 0 V, V4 = 3.0 V.
13. DO pin resistance "L"
(Test circuit 4)
The DO pin resistance "L" (R_DOL) is the resistance between VSS pin and DO pin under the set conditions of V1 = 1.8 V,
V2 = 0 V, V4 = 0.4 V.
14. Overcharge detection delay time
(Test circuit 5)
The overcharge detection delay time (t_CU) is the time needed for V_CO to go to "L" just after the voltage V1 increases and
exceeds V_CU under the set conditions of V1 = 3.4 V, V2 = 0 V.
15. Overdischarge detection delay time
(Test circuit 5)
The overdischarge detection delay time (t_DL) is the time needed for V_DO to go to "L" after the voltage V1 decreases and
falls below V_DL under the set conditions of V1 = 3.4 V, V2 = 0 V.
