为什么CHG 和 DSG 的电压都是参考VC2? 不是DSG 参考Vpack, 而CHG 参考 VC2吗？
您好，CHG 和 DSG有charge pump 电压比正常的cell电压高。CHG 参考 VC2, DSG 参考Vpack,就是充放电MOS的栅极
V(FETON)Output voltage,CHG and DSG onVDSG(ON) = VDSG – VVC2, 4.07 V ≤ VVC2 ≤ 18 V, 10 MΩbetween PACK and DSG 8.75 9.5 10.25VVCHG(ON) = VCHG – VVC2, 4.07 V ≤ VVC2 ≤ 18 V, 10 MΩbetween VC2 and CHG 8.75 9.5 10.25
为什么都是VVC2呢？VDSG(ON)=VDSG-Vpack,这样才对的吧？
