Measurement Conditions
Over-charge detection voltage --- [Circuit 1]
Set V1 = 3.0V and V2 = 0V. Over-charge detection voltage VC is V1 at which VCO goes "Low" from "High" when V1
is gradually increased from 3.0V. Then IC is released from the over-charge state and VCO goes "High" from "Low" at
the voltage "Measured VC" when V1 is gradually decreased.
Over-discharge detection voltage --- [Circuit 1]
Set V1 = 3.0V and V2 = 0V. Over-discharge detection voltage Vdc is V1 at which VDO goes "Low" from "High" when
V1 is gradually decreased from 3.0V. Next, set V2 under to charge over-current detection voltage VIc. Then IC is
released from the over-discharge state at Vdc and VDO goes "High" from "Low".
Charge over-current detection voltage --- [Circuit 2]
Set V1 = 3.0V and V2 = 0V. Charge over-current detection voltage VIc is V2 at which VCO goes "Low" from "High"
when V2 is gradually decreased from 0V.
Discharge over-current detection voltage --- [Circuit 2]
Set V1 = 3.0V and V2 = 0V. Discharge over-current detection voltage VIdc is V2 at which VDO goes "Low" from
"High" when V2 is gradually increased from 0V.
Load short-circuiting detection voltage --- [Circuit 2]
Set V1 = 3.0V and V2 = 0V. Load short-circuiting detection voltage Vshort is V2 at which VDO goes "Low" from
"High" within a time between the minimum and the maximum value of load short-circuiting detection delay time tshort,
when V2 is increased rapidly within 10
μs.
0V battery charge starting charger voltage --- [Circuit 3]
Set V1 = V2 = 0V and decrease V2 gradually. 0V battery charge starting charger voltage Vcha is V2 when VCO goes
"High" (V1-0.1V or higher).
