Judge the CO pin level with respect to VVM and the DO pin level with respect to VSS. (1) Measurement Condition 1, Measurement Circuit 1 <Overcharge detection voltage, Overcharge hysteresis 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 starting condition V1=3.5V. The overcharge hysteresis voltage (VHC) is then defined by the difference between the overcharge detection voltage (VCU) and the voltage between VDD and VSS at which VCO goes “H” wwwfr.oDmata“SLh”eewt4hUe.ncotmhe voltage V1 is gradually decreased. (2) Measurement Condition 2, Measurement Circuit 2 <Overdischarge detection voltage, Overdischarge hysteresis voltage > The overdischarge detection voltage (VDL) is defined by the voltage between VDD and VSS at which VDO goes “L” from “H” when the voltage V1 is gradually decreased from the starting condition V1=3.5V and V2 =0V. The overdischarge hysteresis voltage (VHD) is then defined by the difference between the overdischarge detection voltage (VDL) and the voltage between VDD and VSS at which VDO goes “H” from “L” when the voltage V1 is gradually increased. (3) Measurement Condition 3, Measurement Circuit 2 <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 VM and VSS at which VDO goes ”L” from “H” when the voltage V2 is gradually increased from the normal condition V1 =3.5V and V2 =0V. The overcurrent 2 detection voltage (VIOV2) is defined by the voltage between VM and VSS at which VDO goes “L” from “H” when the voltage V2 is increased at the speed between 1ms and and 4ms from the normal condition V1=3.5V and V2 = 0V. 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 1µs and 50µs from the normal condition V1=3.5V and V2=0V. EUP9261 (4) Measurement Condition 4, Measurement Circuit 2 <Charger detection voltage, abnormal charge current detection voltage.> Set V1=1.8V and V2=0V. Increase V1 gradually until V1=VDL+(VHD/2) , then decrease V2 from 0V gradually. The voltage between VM and VSS when VDO goes “H” from “L” is the charger detection voltage (VCHA). Charger detection voltage can be measured only in the product whose overdischarge hysteresis VHD ≠ 0. Set V1=3.5V and V2=0V. Decrease V2 from 0V gradually. The voltage between VM 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 (VCHA). (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 (IOPE). Set V1=V2=1.5V under overdischarge condition. The current IDD flowing through VDD pin is the power-down current consumption (IPDN). (6) Measurement Condition 6, Measurement Circuit 3 < Internal resistance between VM and VDD, Internal resistance between VM and VSS. > Set V1=1.8V and V2=0V. The resistance between VM and VDD is the internal resistance (RVMD) between VM and VDD. Set V1=3.5V and V2=1.0V. The resistance between VM and VSS is the internal resistance (RVMS) between VM and VSS. (7) Measurement Condition 7, Measurement Circuit 4 <CO pin H resistance, CO pin L resistance> Set V1=3.5V, V2=0V and V3=3.0V. CO pin resistance is the CO pin H resistance (RCOH). Set V1=4.5V, V2=0V and V3=0.5V. CO pin resistance is the CO pin L resistance (RCOL). (8) Measurement Condition 8, Measurement Circuit 4 <DO pin H resistance, DO pin L resistance.> Set V1=3.5V, V2=0V and V4=3.0V. DO pin resistance is the DO pin H resistance (RDOH).Set V1=1.8V,V2= 0V and V4=0.5 V. DO pin resistance is the DO pin L resistance (RDOL). DS9261 Ver2.4 Jan. 2007 11 11 Page
