(Charger detection voltage, abnormal charge current detection voltage)
Set V1=1.8V and V2=0V. Increase V1 gradually until V1=VDET2 +(VHDT2 /2), then decrease V2 from 0
V gradually. The voltage between V- and VSS when VDO goes “H” from “L” is the charger detection
voltage (VDET5). Charger detection voltage can be measured only in the product whose over-discharge
hysteresis VHDT2 0.
Set V1=3.5V and V2=0V, Decrease V2 from 0 V gradually. The voltage between V- and VSS when VCO
goes “L” from “H” is the abnormal charge current detection voltage. The abnormal charge current detection
voltage has the same value as the charger detection voltage (VDET5).
(5) Measurement Condition 5, Measurement Circuit 2
(Normal operation current consumption, Power-down current consumption)
Set V1=3.5V and V2=0V under normal condition. The current IDD flowing through VDD pin is the
normal operation consumption current (IDD).
Set V1=V2=1.5V under over-discharge condition. The current IDD flowing through VDD pin is the
power-down current consumption (ISB).
(6) Measurement Condition 6, Measurement Circuit 3
(Internal resistance between V- and VDD, Internal resistance between V- and VSS)
Set V1=1.8V and V2=0V. The resistance between V- and VDD is the internal resistance (RV-D) between
V- and VDD. Set V1=3.5V and V2=1.0V. The resistance between V- and VSS is the internal resistance
(RV-S) between V- and VSS.
(7) Measurement Condition 7, Measurement Circuit 4
(COUT pin H resistance, COUT pin L resistance)
Set V1=3.5V, V2=0V and V3=3.0V. COUT pin resistance is the COUT pin H resistance (RCOUTH ).
Set V1=4.5V, V2=0V and V3=0.5V. COUT pin resistance is the COUT pin L resistance (RCOUTL )
.
(8) Measurement Condition 8, Measurement Circuit 4
(DOUT pin H resistance, DOUT pin L resistance)
Set V1=3.5V, V2=0V and V4=3.0V. DOUT pin resistance is the DOUT pin H resistance (RDOUTH ).
Set V1=1.8V, V2=0V and V4=0.5V. DOUT pin resistance is the DOUT pin L resistance (RDOUTL ).
(9) Measurement Condition 9, Measurement Circuit 5
(Overcharge detection delay time, Over-discharge detection delay time)
The overcharge detection delay time (tVDET1) is the time needed for VCO to change from "H" to "L" just
after the V1 rapid increase within 10us from the overcharge detection voltage (VDET1) - 0.2V to the
