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 (0 V battery charge function "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 (0 V battery charge function "unavailable")
(Test condition 12, test circuit 2)
The 0 V battery charge inhibition battery 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.
