 Test Circuit
1. Current Consumption during Operation and Power-down (Test Circuit 1)
Set S1 and S2 to OFF.
1. 1 Current Consumption during Operation (I_OPE)
Set V1 = V2 = V3 = V4 = 3.5 V (S-8205A Series), V1 = V2 = V3 = V4 = V5 = 3.5 V (S-8205B Series), S2 to ON.
I_SS is the current consumption during operation (I_OPE) at that time.
1. 2 Current Consumption during Power-down (I_PDN) (With power-down function)
Set V1 = V2 = V3 = V4 = 1.5 V (S-8205A Series), V1 = V2 = V3 = V4 = V5 = 1.5 V (S-8205B Series), S1 to ON.
I_SS is the current consumption during power-down (I_PDN) at that time.

Set S3 to OFF.
Confirm both V_CO and V_DO are in "H" (its voltage level is V_DS × 0.9 V or more) after setting V1 = V2 = V3 = V4 = 3.5 V
(S-8205A Series), V1 = V2 = V3 = V4 = V5 = 3.5 V (S-8205B Series), V6 = V7 = V8 = 0 V (this status is referred to
as initial status 1).
2. 1 Overcharge Detection Voltage (V_CU1), Overcharge Release Voltage (V_CL1)
The overcharge detection voltage (V_CU1) is V1 when the V_CO is set to "L" (its voltage level is V_DS × 0.1 V or less)
after increasing V1 gradually after setting V1 = V2 = V3 = V4 = V_CU − 0.05 V (S-8205A Series), V1 = V2 = V3 = V4
= V5 = V_CU − 0.05 V (S-8205B Series) from the initial status 1. After that, decreasing V1 gradually, V1 is the
overcharge release voltage (V_CL1) when the V_CO is set to "H" after setting V2 = V3 = V4 = 3.5 V (S-8205A Series),
V2 = V3 = V4 = V5 = 3.5 V (S-8205B Series).
2. 2 Overdischarge Detection Voltage (V_DL1), Overdischarge Release Voltage (V_DU1)
The overdischarge detection voltage (V_DL1) is V1 when the V_DO is set to "L" after decreasing V1 gradually from the
initial status 1. After that, increasing V1 gradually, V1 is the overdischarge release voltage (V_DU1) when V_DO is set
to "H".
By changing Vn (n = 2 to 4: S-8205A Series, n = 2 to 5: S-8205B Series), users can define the overcharge
detection voltage (V_CUn), the overcharge release voltage (V_CLn), the overdischarge detection voltage (V_DLn), the
overdischarge release voltage (V_DUn) as well when n = 1.
2. 3 Discharge Overcurrent Detection Voltage (V_DIOV)
The discharge overcurrent detection voltage (V_DIOV) is V6 when V_DO is set to "L" after increasing V6 gradually from
the initial status 1.
2. 4 Load Short Circuit Detection Voltage (V_SHORT)
The load short circuit detection voltage (V_SHORT) is V6 when V_DO is set to "L" after increasing V6 gradually after
setting S3 to ON from the initial status 1.
2. 5 Charge Overcurrent Detection Voltage (V_CIOV)
The charge overcurrent detection voltage (V_CIOV) is V6 when V_CO is set to "L" after decreasing V6 gradually from
the initial status 1.
2. 6 CTLC Pin Change Voltage (V_CTLC)
The CTLC pin change voltage (V_CTLC) is V7 when V_CO is set to "L" after increasing V7 gradually from the initial
status 1.
2. 7 CTLD Pin Change Voltage (V_CTLD)
The CTLD pin change voltage (V_CTLD) is V8 when V_DO is set to "L" after increasing V8 gradually from the initial
status 1.
