9 / 24 page  BATTERY MONITORING IC FOR 3-SERIAL TO 5-SERIAL CELL PACK Rev.1.5_01 S-8225B Series 9 6. SEL1 pin voltage "H" (VSELH1), SEL2 pin voltage "H" (VSELH2), SEL1 pin voltage "L" (VSELL1), SEL2 pin voltage "L" (VSELL2) (Test circuit 3) VSELH1 is defined as the voltage V8 when V8 is gradually increased and the DO pin output becomes release status after setting V1 = V2 = V3 = V5 = 3.5 V, V4 = 0 V, V6 = V7 = VDS (= V1 + V2 + V3 + V4 + V5), V8 = V9 = 0 V. After that, VSELL1 is defined as the voltage V8 when V8 is gradually decreased and the DO pin output becomes detection status. Moreover, VSELH2 is defined as the voltage V9 when V9 is gradually increased and the DO pin output becomes release status after setting V1 = V2 = V3 = V4 = 3.5 V, V5 = 0 V, V6 = V7 = VDS (= V1 + V2 + V3 + V4 + V5), V8 = V9 = 0 V. After that, VSELL2 is defined as the voltage V9 when V9 is gradually decreased and the DO pin output becomes detection status. 7. CO pin voltage "H" (VCOH), DO pin voltage "H" (VDOH) (Test circuit 4) 7. 1 CO pin output logic active "H" VCOH is defined as the voltage between the CO pin and the VSS pin when V1 = 6.8 V, V2 = 0 V, V3 = V4 = V5 = 3.4 V. 7. 2 CO pin output logic active "L" VCOH is defined as the voltage between the CO pin and the VSS pin when V1 = V2 = V3 = V4 = V5 = 3.4 V. 7. 3 DO pin output logic active "H" VDOH is defined as the voltage between the DO pin and the VSS pin when V1 = 6.8 V, V2 = 0 V, V3 = V4 = V5 = 3.4 V. 7. 4 DO pin output logic active "L" VDOH is defined as the voltage between the DO pin and the VSS pin when V1 = V2 = V3 = V4 = V5 = 3.4 V. 8. CO pin source current (ICOH), CO pin sink current (ICOL), DO pin source current (IDOH), DO pin sink current (IDOL) (Test circuit 7) 8. 1 CO pin output logic active "H" ICOH is defined as the CO pin current when V1 = 6.8 V, V2 = 0 V, V3 = V4 = V5 = 3.4 V, V6 = VCOH − 0.5 V. ICOL is defined as the CO pin current when V1 = V2 = V3 = V4 = V5 = 3.4 V, V6 = 0.5 V. 8. 2 CO pin output logic active "L" ICOH is defined as the CO pin current when V1 = V2 = V3 = V4 = V5 = 3.4 V, V6 = VCOH − 0.5 V. ICOL is defined as the CO pin current when V1 = 6.8 V, V2 = 0 V, V3 = V4 = V5 = 3.4 V, V6 = 0.5 V. 8. 3 DO pin output logic active "H" IDOH is defined as the DO pin current when V1 = 6.8 V, V2 = 0 V, V3 = V4 = V5 = 3.4 V, V7 = VDOH − 0.5 V. IDOL is defined as the DO pin current when V1 = V2 = V3 = V4 = V5 = 3.4 V, V7 = 0.5 V. 8. 4 DO pin output logic active "L" IDOH is defined as the DO pin current when V1 = V2 = V3 = V4 = V5 = 3.4 V, V7 = VDOH − 0.5 V. IDOL is defined as the DO pin current when V1 = 6.8 V, V2 = 0 V, V3 = V4 = V5 = 3.4 V, V7 = 0.5 V. |
