Qualcomm QC2 0 era

Lub charger thawj kauj ruam hauv tsev neeg tus qauv voltage ntawm 220V rau 5V tso zis rau microUSB interface ntawm lub xov tooj ntawm tes ob peb xyoos dhau los (lub npe hu ua Android lub taub hau), thiab tom qab ntawd lub hauv paus ntawm lub xov tooj ntawm tes tau nqis mus txog. 4.3V them lub roj teeb. Muaj ob kauj ruam hauv cov nyiaj npib.

Ua ntej QC1.0, txhua leej txhua tus tau xav txog yuav ua li cas nce qhov tam sim no. Nyob rau hauv lub era ntawm QC1.0, uas yog, nyob rau hauv lub era ntawm 5V2A, thawj cov ntaub ntawv kab tau raug cuam tshuam los ntawm lub fwj. Yog tias qhov tam sim no tseem nce ntxiv, nws yuav ua rau muaj kev puas tsuaj rau cov kab them nyiaj. Cov kab hluav taws xob zoo tib yam tuaj yeem dhau 2A, thiab cov kab them nyiaj zoo dua tuaj yeem ncav cuag 3A. Qhov zoo tshaj plaws vooc charging kab zoo li oppo tuaj yeem ncav cuag 4A (qhov no tom qab).

Yog li ntawd, Qualcomm xav txog kev nce lub zog them los ntawm kev ua kom lub zog them, yog li QC2.0 tau yug los. Qualcomm faib QC2.0 ua ob pawg: Chav A thiab Chav B. Chav A muab 5V, 9V, thiab 12V voltages. Chav B muab 5V, 9V, 12V, thiab 20V voltages, uas 20V yog rau phau ntawv. (Ntawm no yog lus ntxhi, lub chargeturbo ceev them ntawm Xiaomi 9 yog qhov tseeb QC3.0ClassB tus qauv, siv 20V1.35A iav kom ua tiav 27V ceev them.), ntawm no dua, Samsung hais rau 5 xyoo ntawm AFC them Nws yog lub tsho khuam ntawm QC 2.0.

Txawm li cas los xij, QC2.0 muaj qhov tsis txaus, uas yog, tus nqi them nqi sib npaug rau hnub no qhov kev them nyiaj tseem qeeb me ntsis, thiab lub xov tooj ntawm tes tsim hluav taws xob ntau (xav tias QC2.0 + Snapdragon 810 processor), vim hais tias lub lithium roj teeb yeej txais tau rau them. Qhov hluav taws xob yog 4.35V (lub lithium-ion roj teeb them hluav taws xob ntawm qee lub xov tooj ntawm tes yog 4.2V thiab 4.4V), yog li qhov tseeb, txawm tias qhov hluav taws xob nkag ntawm USB interface ntawm lub xov tooj ntawm tes yog 5V lossis 20V, qhov hluav taws xob sab hauv ntawm lub xov tooj ntawm tes yuav tsum tau nruab nrog ib kauj ruam-down Circuit Court kom txo cov input voltage. 4, 35v. Txawm li cas los xij, 20V voltage hauv lub xov tooj ntawm tes kom ua tiav 4.35V kauj ruam-down hloov dua siab tshiab yuav tsim kom muaj cua sov ntau, ua rau lub xov tooj them nyiaj kub siab dhau lawm, nws yog qhov pheej hmoo tawg.

Thiab QC2. Kev tuav tes raws tu qauv ntawm QC2.0 sib txuas lus nrog DP (D+, DigitalPositive) thiab DM (D-, DigitalMinus) ob-pin cov ntaub ntawv terminals ntawm Micro-USB / USB-A / USB-C interface, thiab lub xov tooj ntse nquag siv rau QC2.0 charger. Lub siab voltage input tuaj yeem ua kom qhov siab tshaj plaws them rau 20V tom qab kev pom zoo. QC2.0, uas yuav tsum tau siv lub zog them nyiaj tshwj xeeb, tau dhau los ua lub neej rau kev lag luam sab saud thiab cov chaw tsim khoom. Txij thaum ntawd los, kev lag luam ceev ceev tau ntsib kev loj hlob tawg.
