(7) Power-down Current Consumption
(Test Condition 5, Test Circuit 2)
The power-down current consumption (I_PDN) is the current that flows through the VDD pin (I_DD) under the set condition
of V1 = V2 = 1.5 V (overdischarge status).
(8) Resistance between VM Pin and VDD Pin
(Test Condition 6, Test Circuit 3)
The resistance between VM pin and VDD pin (R_VMD) is the resistance between VM pin and VDD pin under the set
conditions of V1 = 1.8 V, V2 = 0 V.
(9) Resistance between VM Pin and VSS Pin
(Test Condition 6, Test Circuit 3)
The resistance between VM pin and VSS pin (R_VMS) is the resistance between VM pin and VSS pin under the set
conditions of V1 = 3.5 V, V2 = 1.0 V.
(10) CO Pin Resistance “H”
(Test Condition 7, Test Circuit 4)
The CO pin resistance “H” (R_COH) is the resistance at the CO pin under the set conditions of V1 = 3.5 V, V2 = 0 V,
V3 = 3.0 V.
(11) CO Pin Resistance “L”
(Test Condition 7, Test Circuit 4)
The CO pin resistance “L” (R_COL) is the resistance at the CO pin under the set conditions of V1 = 4.5 V, V2 = 0 V,
V3 = 0.5 V.
(12) DO Pin Resistance “H”
(Test Condition 8, Test Circuit 4)
The DO pin H resistance (R_DOH) is the resistance at the DO pin under the set conditions of V1 = 3.5 V, V2 = 0 V,
V4 = 3.0 V.
(13) DO Pin Resistance “L”
(Test Condition 8, Test Circuit 4)
The DO pin L resistance (R_DOL) is the resistance at the DO pin under the set conditions of V1 = 1.8 V, V2 = 0 V, V4 = 0.5 V.
(14) Overcharge Detection Delay Time
(Test Condition 9, Test Circuit 5)
The overcharge detection delay time (t_CU) is the time needed for V_CO to change from “H” to “L” just after the voltage
V1 momentarily increases (within 10 µs) from overcharge detection voltage (V_CU) −0.2 V to overcharge detection
voltage (V_CU) +0.2 V under the set condition of V2 = 0 V.
(15) Overdischarge Detection Delay Time
(Test Condition 9, Test Circuit 5)
The overdischarge detection delay time (t_DL) is the time needed for V_DO to change from “H” to “L” just after the voltage
V1 momentarily decreases (within 10 µs) from overcharge detection voltage (V_DL) +0.2 V to overcharge detection
voltage (V_DL) −0.2 V under the set condition of V2 = 0 V.
