 Test Circuits
Caution Unless otherwise specified, the output voltage levels "H" and "L" at CO pin (VCO) and DO pin (VDO) are
judged by the threshold voltage (1.0 V) of the N-channel FET. Judge the CO pin level with respect to VVM
and the DO pin level with respect to VSS.
1. Overcharge detection voltage, overcharge release voltage
(Test circuit 1)
Overcharge detection voltage (VCU) is defined as the voltage V1 at which VCO goes from "H" to "L" when the voltage V1
is gradually increased from the starting condition of V1 = 3.4 V. Overcharge release voltage (VCL) is defined as the
voltage V1 at which VCO goes from "L" to "H" when the voltage V1 is then gradually decreased. Overcharge hysteresis
voltage (VHC) is defined as the difference between VCU and VCL.
2. Overdischarge detection voltage, overdischarge release voltage
(Test circuit 2)
Overdischarge detection voltage (VDL) is defined as the voltage V1 at which VDO goes from "H" to "L" when the voltage
V1 is gradually decreased from the starting condition of V1 = 3.4 V, V2 = 0 V. Overdischarge release voltage (VDU) is
defined as the voltage V1 at which VDO goes from "L" to "H" when the voltage V1 is then gradually increased.
Overdischarge hysteresis voltage (VHD) is defined as the difference between VDU and VDL.
3. Discharge overcurrent detection voltage
(Test circuit 2)
Discharge overcurrent detection voltage (VDIOV) is defined as the voltage V2 whose delay time for changing VDO from
"H" to "L" is discharge overcurrent delay time (tDIOV) when the voltage V2 is increased from the starting condition of
V1 = 3.4 V, V2 = 0 V.
4. Load short-circuiting detection voltage
(Test circuit 2)
Load short-circuiting detection voltage (VSHORT) is defined as the voltage V2 whose delay time for changing VDO from
"H" to "L" is load short-circuiting delay time (tSHORT) when the voltage V2 is increased from the starting condition of
V1 = 3.4 V, V2 = 0 V.
5. Charge overcurrent detection voltage
(Test circuit 2)
Charge overcurrent detection voltage (VCIOV) is defined as the voltage V2 whose delay time for changing VCO from "H" to
"L" is charge overcurrent delay time (tCIOV) when the voltage V2 is decreased from the starting condition of V1 = 3.4 V,
V2 = 0 V.
6. Current consumption during operation
(Test circuit 2)
The current consumption during operation (IOPE) is the current that flows through the VDD pin (IDD) under the set
conditions of V1 = 3.4 V and V2 = 0 V.
7. Current consumption during power-down, current consumption during overdischarge
(Test circuit 2)
7. 1 With power-down function
The current consumption during power-down (IPDN) is IDD under the set conditions of V1 = V2 = 1.5 V.
7. 2 Without power-down function
The current consumption during overdischarge (IOPED) is IDD under the set conditions of V1 = V2 = 1.5 V.
