16. Discharge overcurrent detection delay time
(Test condition 10, test circuit 5)
Discharge overcurrent detection delay time (tDIOV) is the time needed for VDO 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 (tSHORT) is the time needed for VDO 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 (tCIOV) is the time needed for VCO 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 battery charge starting charger voltage (V0CHA) is defined as the voltage between the VDD pin and VM pin at
which VCO goes to "H" (VVM + 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 (V0INH) is defined as the voltage between the VDD pin and VSS pin
at which V CO goes to "H" (VVM + 0.1 V or higher) when the voltage V1 is gradually increased from the starting
conditions of V1 = 0 V, V2 = −4 V.
