MITSUMI Lithium-Ion Battery Charge Control IC MM3358 Item Symbol Measurement circuit Measuring circuit Forced charge time (*1) Tistart C When increasing VF1 from 2.3V to 5.0V under the condition of VF10=3.6V, measure the time from forced charge start(|I10|>1mA) to forced charge stop(|I10|<1mA). Forced charge OFF time (*1) Toff C After increasing VF1 from 2.3V to 5.0V under the condition of VF10=3.6V, the half time from forced charge stop(|I10|<1mA) to fast charge start(|I10|>1mA) should be Toff. Battery voltage detection time (*1) Tcon C When decreasing VF10 from 4.25V to 3.8V after charge complete mode under the condition of VF10=4.25V, the half time from when the current of I9 exceeds 100µA to when V3=Low to High and the charging restarts(|I10|>1mA) should be Tcon. Fast charge start voltage detection time (*1) Tqstart C When increasing VF10 from 2.6V to 3.6V under the condition of trickle charge mode, VF10=2.6V, and R8=2.32kΩ, measure the time from when VF10>3.0V(Vqchgon) to when fast charge starts(|I10|>530mA). Charge completion current detection time (*1) Tifc F When decreasing IF10 from-80mA to -30mA under the condition of fast charge mode and R8=2.32kΩ, measure the time from when IF10>-56mA(Ifc) to when the charging stops (I10>-1mA). Recharge start voltage detection time (*1) Trechg C When decreasing VF10 from 4.25V to 3.8V after charge completion mode under the condition of VF10=4.25V, measure the time from when VF10<3.97V(Vrechg) to when the current of I9 exceeds 100µA. Trickle-charge timer (*1) Tdchg C When decreasing VF7 from 5.0V to 0V under the condition of trickle charge mode, VF7=5.0V, VF10=2.6V, and time reduction mode(See Pin description), measure the time from when VF10<0.5V (Vtmr) to when V3 starts blinking(V3=High to Low, charge error mode) and the charging stops(|I10|<1mA). Tdchg=Tdchg2×2.304E + 08/109 in time reduction mode due to a TH pin. Fast-charge timer (*1) Tchg C When decreasing VF7 from 5.0V to 0V under the condition of fast charge mode, VF7=5.0V, VF10=3.6V, and time reduction mode(See Pin description), measure Tchg2 that is the time from when VF10<0.5V(Vtmr) to when V3 starts blinking(V3=High to Low, charge error mode) and the charging stops (|I10|<1mA). Tchg=Tchg2×1.152E + 09/137 in time reduction mode due to a TH pin. Battery overvoltage detection time (*1) Tov C When increasing VF10 from 3.6V to 4.5V under the condition of fast charge mode and VF10=3.6V, measure the time from when VF10>4.35V(Vov) to when V3 starts blinking (V3=High to Low, charge error mode). Charge stop temperature detection time (*1) Tpro C When increasing(decreasing) VF6 from 1.0V to 2.0V(0V) under the condition of fast charge mode, VF6=1.0V, and VF10=3.6V, measure the time from when VF6>VthSL(VF6<VthSH) to when V3=High to Low and the charging stops(|I10|<1mA). Charge recovery temperature detection time (*1) Tpro C When decreasing (increasing) VF6 from 2.0V(0V) to 1.0V under the condition of charge stop detection mode, VF6=2.0V(0V), and VF10=3.6V, measure the time from when VF6<VthRL(VF6>VthRH) to when V3=Low to High and the charging restarts (|I10|>1mA). note : 1 The parameter is guaranteed by design. |
