Test Circuit
In this chapter, describing how to test the S-8204A Series. In case of selecting to use it for 4-series cell
battery, set SEL pin = VDD level. For 3-series cell battery, set SEL pin = VSS level and short between VC3 and
VC4 pin.
1. Current consumption during operation and power-down (Test circuit 1)
1. 1 Current Consumption during Operation (IOPE)
The current at the VSS pin when V1 = V2 = V3 = V4 = 3.5 V and VVMP = VDD is the current
consumption during operation (IOPE).
1. 2 Current Consumption at Power-down (IPDN)
The current at the VSS pin when V1 = V2 = V3 = V4 = 1.5 V and VVMP = VSS is the current
consumption at power-down (IPDN).
2. Overcharge Detection Voltage, Overcharge Release Voltage, Overdischarge Detection Voltage,
Overdischarge Release Voltage, Discharge Overcurrent Detection Voltage 1, Discharge
Overcurrent Detection Voltage 2, Short circuit detection voltage, Charge Overcurrent Detection
Voltage, CTLC Input Voltage “H”, CTLC Input Voltage “L”, CTLD Input Voltage “H”, CTLD Input
Voltage “L”, SEL Input Voltage “H”, SEL Input Voltage “L” (Test circuit 2)
Confirm both COP and DOP pins are in “L” (its voltage level is VDS
× 0.1 V or less) after setting VVMP =
VSEL = VDD, VVINI = VCTLC = VCTLD = VSS, CCT pin = Open, CDT pin = Open, CIT pin = Open, V1 = V2 =
V3 = V4 = 3.5 V. (This status is referred to as initial state.)
2. 1 Overcharge Detection Voltage (VCU1), Overcharge Release Voltage (VCL1)
The overcharge detection voltage (VCU1) is a voltage at V1; when the COP pin’s voltage is set to “H”
(its voltage level is VDS
× 0.9 V or more) after increasing a voltage at V1 gradually from the initial state.
After that, decreasing a voltage at V1 gradually, a voltage at V1 when the COP pin’s voltage is set to
“L”; is the overcharge release voltage (VCL1).
2. 2 Overdischarge Detection Voltage (VDL1), Overdischarge Release Voltage (VDU1)
The overdischarge detection voltage (VDL1) is a voltage at V1; when the DOP pin’s voltage is set to “H”
after decreasing a voltage at V1 gradually from the initial state. After that, increasing a voltage at V1
gradually, a voltage at V1 when the DOP pin’s voltage is set to “L”; is the overdischarge release
voltage (VDU1).
By changing the voltage at Vn (n = 2 to 4), users can define the overcharge detection voltage (VCUn),
the overcharge release voltage (VCLn), the overdischarge detection voltage (VDLn), the overdischarge
release voltage (VDUn) as well when n = 1.
2. 3 Discharge Overcurrent Detection Voltage 1 (VDIOV1)
The discharge overcurrent detection voltage 1 (VDIOV1) is the VINI pin’s voltage; when the DOP pin’s
voltage is set to “H” after increasing the VINI pin’s voltage gradually from the initial status.
2. 4 Discharge Overcurrent Detection Voltage 2 (VDIOV2)
The discharge overcurrent detection voltage 2 (VDIOV2) is a voltage at the VINI pin; when a flowing
current from the CIT pin reaches 500
A or more after increasing the VINI pin’s voltage gradually from
the initial status.
