♠ BQ25611D I2C Whakahaerehia 1-Cell 3.0-A Buck Battery Charger me te USB Detection me te 1.2-A Boost Operation
Ko te BQ25611D he tino whakauru 3-A switchmode whakahaere utu pākahiko me te punaha whakahaere ara hiko mo nga pākahiko Li-Ion me Lipolymer pūtau kotahi. Ko te otinga he tino whakauru ki te whakauru whakamuri-aukati FET (RBFET, Q1), FET whakawhiti teitei (HSFET, Q2), FET whakawhiti taha iti (LSFET, Q3), me te FET pākahiko (BATFET, Q4) i waenga i te punaha me te pākahiko. Ko te ara hiko impedance iti e arotau ana i te pai o te mahi aratau-whakawhiti, te whakaiti i te wa e utu ana te pākahiko me te whakaroa atu i te wa oma o te pākahiko i te wa o te tuku.
Ko te BQ25611D he tino whakauru 3-A switchmode whakahaere utu pākahiko me te punaha whakahaere Ara hiko mo nga pākahiko Li-ion me Li-polymer. E whakaatu ana i te utu tere me te tautoko ngaohiko whakauru teitei mo te whānuitanga o nga tono tae atu ki nga waea atamai me nga papa. Ko tana ara iti o te hiko impedance e arotau ana i te pai o te mahi aratau-whakawhiti, te whakaiti i te wa e utu ana te pākahiko, me te whakaroa i te wa oma o te pākahiko i te wa e tuku ana. Ko tana ngaohiko whakauru me te ture o naianei me te maarama mamao o te pākahiko ka tuku te mana utu nui ki te pākahiko.
