Measurement Circuits
Unless otherwise specified, the output voltage levels "H" and "L" at CO and DO pins are judged by the
threshold voltage (1.0 V) of a Nch FET. Judge the CO pin level with respect to VVM and the DO pin level with
respect to VSS. Voltages V1 to V4 are shown in the figure 4.
(1) Measurement Condition 1, Measurement Circuit 1
Overcharge detection voltage, Overcharge release voltage, Overdischarge detection voltage,
Overdischarge release voltage
The overcharge detection voltage (VCU) is defined by the voltage between VDD and VSS at which VCO goes
″L″ from ″H″ when the voltage V1 is gradually increased from the normal condition V1=3.5 V and
V2=0 V. The overcharge release voltage (VCL) is defined by the voltage between VDD and VSS at which
VCO goes
″H″ from ″L″ when the voltage V1 is then gradually decreased.
Gradually decreasing the voltage V1, the overdischarge detection voltage (VDL) is defined by the voltage
between VDD and VSS at which VDO goes
″L″ from ″H″. The overdischarge release voltage (VDU) is
defined by the voltage between VDD and VSS at which VDO goes
″H″ from ″L″ when the voltage V1 is then
gradually increased.
(2) Measurement Condition 2, Measurement Circuit 1
Overcurrent 1 detection voltage, Overcurrent 2 detection voltage, Load short-circuiting detection voltage
The overcurrent 1 detection voltage (VIOV1) is defined by the voltage between VDD and VSS at which VDO
goes
″L″ from ″H″ when the voltage V2 is gradually increased from the normal condition V1=3.5 V and
V2=0 V.
The overcurrent 2 detection voltage (VIOV2) is defined by the voltage between VDD and VSS at which VDO
goes
″L″ from ″H″ when the voltage V2 is increased at the speed between 1 ms and 4 ms from the normal
condition V1=3.5 V and V2=0 V.
The load short-circuiting detection voltage (VSHORT) is defined by the voltage between VDD and VSS at
which VDO goes
″L″ from ″H″ when the voltage V2 is increased at the speed between 1 s and 50 s from
the normal condition V1=3.5 V and V2=0 V.
(3) Measurement Condition 3, Measurement Circuit 1
Charger detection voltage, (=abnormal charge current detection voltage)
Applied only for products with overdischarge hysteresis
Set V1=1.8 V and V2=0 V under overdischarge condition. Increase V1 gradually, set V1=(VDU+VDL)/2
(within overdischarge hysteresis, overdischarge condition), then decrease V2 from 0 V gradually. The
voltage between VM and VSS at which VDO goes
″H″ from ″L″ is the charger detection voltage (VCHA).
Applied only for products without overdischarge hysteresis
Set V1=3.5 V and V2=0 V under normal condition. Decrease V2 from 0 V gradually. The voltage
between VM and VSS at which 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
(VCHA).
