(16) Discharge Overcurrent Detection Delay Time
(Test Condition 10, Test Circuit 5)
Discharge overcurrent detection delay time (t_DIOV) is the time needed for V_DO to go to “L” after the voltage V2
momentarily increases (within 10 µs) from 0 V to 0.35 V under the set conditions of V1 = 3.5 V, V2 = 0 V.
(17) Load Short-circuiting Detection Delay Time
(Test Condition 10, Test Circuit 5)
Load short-circuiting detection delay time (t_SHORT) is the time needed for V_DO to go to “L” after the voltage V2
momentarily increases (within 10 µs) from 0 V to 1.6 V under the set conditions of V1 = 3.5 V, V2 = 0 V.
(18) Charge Overcurrent Detection Delay Time
(Test Condition 10, Test Circuit 5)
Charge overcurrent detection delay time (t_CIOV) is the time needed for V_CO to go to “L” after the voltage V2
momentarily decreases (within 10 µs) from 0 V to −0.3 V under the set conditions of V1 = 3.5 V, V2 = 0 V.
(19) 0 V Battery Charge Starting Charger Voltage (Products with 0 V Battery Charging Function Is “Available”)
(Test Condition 11, Test Circuit 2)
The 0 V charge starting charger voltage (V_0CHA) is defined as the voltage between the VDD pin and VM pin at which
V_CO goes to “H” (V_VM +0.1 V or higher) when the voltage V2 is gradually decreased from the starting condition of
V1 = V2 = 0 V.
(20) 0 V Battery Charge Inhibition Battery Voltage (Products with 0 V Battery Charging Function Is
“Unavailable”)
(Test Condition 12, Test Circuit 2)
The 0 V charge inhibition charger voltage (V_0INH) is defined as the voltage between the VDD pin and VSS pin at which
V_CO goes to “H” (V_VM +0.1 V or higher) when the voltage V1 is gradually increased from the starting conditions of
V1 = 0 V, V2 = −4 V.
