16. Discharge overcurrent detection delay time

(Test circuit 5)

The discharge overcurrent detection delay time (tDIOV) is the time needed for VDO to go to "L" after the voltage V2

increases and exceeds VDIOV under the set conditions of V1 = 3.4 V, V2 = 0 V.

17. Load short-circuiting detection delay time

(Test circuit 5)

The load short-circuiting detection delay time (tSHORT) is the time needed for VDO to go to "L" after the voltage V2

increases and exceeds VSHORT under the set conditions of V1 = 3.4 V, V2 = 0 V.

18. Charge overcurrent detection delay time

(Test circuit 5)

The charge overcurrent detection delay time (tCIOV) is the time needed for VCO to go to "L" after the voltage V2

decreases and falls below VCIOV under the set conditions of V1 = 3.4 V, V2 = 0 V.

19. 0 V battery charge starting charger voltage (0 V battery charge function "available")

(Test circuit 2)

The 0 V battery charge starting charger voltage (V0CHA) is defined as the absolute value of voltage V2 at which VCO

goes to "H" (VCO = VDD) 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 circuit 2)

The 0 V battery charge inhibition battery voltage (V0INH) is defined as the voltage V1 at which VCO goes to "L" (VCO =

VVM) when the voltage V1 is gradually decreased, after setting V1 = 1.9 V, V2 =

−4.0 V.
