MEASUREMENT CONDITIONS
z Over-charge detection voltage, Over-charge hysteresis voltage --- [Circuit 1]
Set V1=3.5V and V2=0V. Over-charge detection voltage Vc is V1 at which VCO goes "Low" from "High" when
V1 is gradually increased from 3.5V. Then IC is released from the over-charge state and VCO goes "High" from
"Low" at the voltage "Measured Vc-VHc" when V1 is gradually decreased.
If V2 is set to the greater value than discharge over-current detection voltage VIdc in the over-charge state, VHc
is canceled and then IC is released from the over-charge state at Vc.
z Over-discharge detection voltage --- [Circuit 1]
Set V1=3.5V and V2=0V. Over-discharge detection voltage Vdc is V1 at which VDO goes "Low" from "High"
when V1 is gradually decreased from 3.5V. 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".
z Charge over-current detection voltage --- [Circuit 2]
Set V1=3.5V 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.
z Discharge over-current detection voltage --- [Circuit 2]
Set V1=3.5V 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.
z Load short-circuiting detection voltage --- [Circuit 2]
Set V1=3.5V 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 10μs.
z 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 ).
z 0V battery charge inhibiting battery voltage --- [Circuit 3]
Set V1=1.8V and V2=0V at first. Then set V2=V1-4.0V. Next, decrease V1 and V2 gradually, maintaining the
relation of V2=V1-4.0V. 0V battery charge inhibiting battery voltage Vinh is V1 when VCO goes "Low" ( V2+0.1V
or lower ).
z Current consumption on operation and shutdown --- [Circuit 4]
Set V1=3.5V and V2=0V on normal condition. IDD shows current consumption on operation Iopr.
Set V1=V2=1.8V on over-discharge condition. IDD shows current consumption on shutdown Isdn.
z CO : Pch ON resistance, CO : Nch ON resistance --- [Circuit 5]
Set V1=3.5V, V2=0V and V3=3.0V. (V1-V3)/|ICO| is Pch ON resistance Rcop.
Set V1=4.6V, V2=0V and V3=0.5V. V3/|ICO| is Nch ON resistance Rcon.
