Rev.1.9_00

BATTERY PROTECTION IC FOR 4-SERIES OR 5-SERIES CELL PACK

S-8205A/B Series

4. 0 V Battery Charge Starting Charger Voltage (0 V Battery Charge Function "Available") (Test

Circuit 4), 0 V Battery Charge Inhibition Battery Voltage (0 V Battery Charge Function

"Unavailable") (Test Circuit 2)

4. 1 0 V Battery Charge Starting Charger Voltage (V0CHA) (0 V Battery Charge Function "Available")

The 0 V battery charge starting charger voltage (V0CHA) is V12 when VCO is 0.1 V or more after increasing V12

gradually after setting V1 = V2 = V3 = V4 = 0 V (S-8205A Series), V1 = V2 = V3 = V4 = V5 = 0 V (S-8205B

Series).

4. 2 0 V Battery Charge Inhibition Battery Voltage (V0INH) (0 V Battery Charge Function "Unavailable")

The 0 V battery charge inhibition battery voltage (V0INH) is V1 when VCO is set to "L" after decreasing V1

gradually from the initial status 1.

5. CTLC Pin Internal Resistance, CTLD Pin Internal Resistance, Resistance between VM Pin and

VDD Pin, Resistance between VM Pin and VSS Pin, VC1 Pin Current, VC2 Pin Current, VC3 Pin

Current, VC4 Pin Current, VC5 Pin Current, CO Pin Source Current, CO Pin Leakage Current,

DO Pin Source Current, DO Pin Sink Current (Test Circuit 5)

Set S1, S5, S6 and S7 to OFF, set S2 and S4 to ON.

Set V1 = V2 = V3 = V4 = 3.5 V (S-8205A Series), V1 = V2 = V3 = V4 = V5 = 3.5 V (S-8205B Series), V6 = V13 =

V14 = V15 = V16 = 0 V (this status is referred to as initial status 3).

5. 1 CTLC Pin Internal Resistance (RCTLC)

In the initial status 3, the value of CTLC pin internal resistance (RCTLC) can be defined by RCTLC = VDS / ICTLC by

using ICTLC.

5. 2 CTLD Pin Internal Resistance (RCTLD)

In the initial status 3, the value of CTLD pin internal resistance (RCTLD) can be defined by RCTLD = VDS / ICTLD by

using ICTLD.

5. 3 Resistance between VM Pin and VDD Pin (RVMD) (With power-down function)

The value of resistance between VM pin and VDD pin (RVMD) can be defined by RVMD = VDS / IVM by using IVM

when setting V1 = V2 = V3 = V4 = 1.8 V (S-8205A Series), V1 = V2 = V3 = V4 = V5 = 1.8 V (S-8205B Series)

from the initial status 3.

5. 4 Resistance between VM Pin and VSS Pin (RVMS)

The value of resistance between VM pin and VSS pin (RVMS) can be defined by RVMS = VDS / IVM by using IVM

when setting V6 = 1.5 V, S2 to OFF, S1 to ON from the initial status 3.

5. 5 VC1 Pin Current (IVC1), VC2 Pin Current (IVC2), VC3 Pin Current (IVC3), VC4 Pin Current (IVC4),

VC5 Pin Current (IVC5)

In the initial status 3, I1 is the VC1 pin current (IVC1), I2 is the VC2 pin current (IVC2), I3 is the VC3 pin current (IVC3),

I4 is the VC4 pin current (IVC4), I5 is the VC5 pin current (IVC5).

5. 6 CO Pin Source Current (ICOH), CO Pin Leakage Current (ICOL)

The CO pin source current (ICOH) is ICO when setting V13 = 0.5 V from the initial status 3. After that, the CO pin

leakage current (ICOL) is ICO when setting V1 = V2 = V3 = V4 = 6 V (S-8205A Series), V1 = V2 = V3 = V4 = V5 =

4.8 V (S-8205B Series), S4 to OFF, S5 to ON.

5. 7 DO Pin Source Current (IDOH), DO Pin Sink Current (IDOL)

The DO pin source current (IDOH) is IDO when setting V14 = 0.5 V, S6 to ON from the initial status 3. After that, the

DO pin sink current (IDOL) is IDO when setting V1 = V2 = V3 = V4 = 1.8 V (S-8205A Series), V1 = V2 = V3 = V4 =

V5 = 1.8 V (S-8205B Series), S6 to OFF, S7 to ON, V15 = 0.5 V.
