Ulwazi lwe-E-mark chip

Inkcazo phambi koHlobo lwe-C (Uhlobo lwe-A, i-TypeB, njl.) lugxininise kwiimpawu "ezinzima" ze-interface ye-USB, njengenani leempawu, imilo ye-interface, iimpawu zombane, njalo njalo.I-TypeC yongeza umxholo "othambileyo" kwisiseko sokuchaza iimpawu "ezinzima" ze-interface ye-USB.I-interface ye-USB (ibhekisa kuphela kwi-TypeC) isusa ukunxulumana ne-USB kwaye ibe luphawu olutsha olunokuhambelana neenkcukacha ze-USB.Emva kokuba i-USB iphuculwe kwinguqulo ye-3.1, i-interfaces ebonakalayo yonke ithatha i-Type C isakhiwo, kwaye i-3.1 ye-3.1 ye-standard ye-USB Type-C yocingo ayifani, nto leyo eyabangela isiphithiphithi esikhulu.Kuze kube ngu-2019, ukuze balungelelanise imisebenzi yabo kunye nokusebenza kombane, umbutho ubeke umda.Ukuba imveliso ifuna ukuxhasa i-5A ephezulu yangoku, i-USB 3.0 okanye isantya esiphezulu sothumelo kunye nomsebenzi wokuphuma kwevidiyo, kufuneka ixhotyiswe nge-E-Marker chip.Uphawu lwe-E, igama elipheleleyo: Ikhebula eliphawulwe ngombane, i-USB Type-C cable esebenzayo epakishwe nge-E-Marker chip, i-DFP kunye ne-UFP inokusebenzisa i-PD protocol ukufunda iimpawu zentambo, kubandakanywa amandla okuhambisa amandla, amandla okudlulisa idatha, Ukulinda kwe-ID. ngolwazi, ukuthetha ngokulula, ukuba intambo yedatha ye-Type-C ine-E-Marker chip (siyibiza ngokuba ileyibhile yombane), i-E-Marker (iCable ye-Electronic Marked Cable) inokuqondwa ngokulula njengeleyibhile yombane yoHlobo-C. umgca.Iimpawu ezisetyenzisiweyo zekhebula zingafundwa nge-E-Marker chip, njengokuhanjiswa kwamandla, ukuhanjiswa kwedatha, ukuhanjiswa kwevidiyo kunye ne-ID.Ngokusekwe koku, i-terminal ephumayo inokulungelelanisa i-voltage ehambelanayo / yangoku okanye isandi kunye neempawu zevidiyo ngokwezixhobo eziqhagamshelweyo ezinjengeefowuni eziphathwayo okanye iimonitha.Ngaphambili, iitshiphusi ze-E-Marker bezisoloko zingeniswa ngaphandle.I-Cypress (iCypress) kunye ne-Intel zineemveliso eziqinileyo ze-E-Marker chip.I-Apple yakhe yakwenza ngokwezifiso i-E-Marker USB 4 chip JHL 7040 esuka kwi-Intel ukuze isetyenziswe kwi-interface ye-Thunderbolt.Kwiminyaka yakutshanje, iichips ezinokuxhasa umenzi we-E wasekhaya nazo sele ziqalisile ukuthengiswa kwiibhetshi kwaye zibe zezona ziphambili.

Umgaqo wokuqala wokusebenzisa uphawu lwe-E: Ukuba ufuna ukubonelela nge-voltage engaphezu kwe-5V okanye yangoku edlula i-3A ngokusebenzisa i-interface ye-USB TYPE-C, ngoko kufuneka ufune i-chip ye-TYPE-C yojongano ukuze kuphunyezwe iprotocol ye-USB PD.

Umgaqo wesibini wokusebenzisa uphawu lwe-E: Ukuba isixhobo sakho sisebenzisa i-5V yombane, kwaye yangoku ayidluli kwi-3A.Kuxhomekeke kwiimpawu zonikezelo lwamandla kunye neempawu zokuhanjiswa kwedatha yesixhobo ngokwaso.Ukuba isixhobo ngokwaso sinikezela kuphela amandla ngaphandle, okanye samkele kuphela amandla avela kwelinye iqela, kwaye indima yonikezelo lwamandla kunye nendima yokuhanjiswa kwedatha ihambelana ngokungagqibekanga (oko kukuthi, iqela lonikezelo lwamandla ngu-HOST, kwaye umsebenzisi wamandla nguMkhoboka. okanye isixhobo), awudingi itshiphu ye-TYPE-C.

Umgaqo wesithathu wokusebenzisa uphawu lwe-E: Le migaqo mibini isetyenziselwa ukugweba ukuba i-chip ye-TYPE-C iyadingeka kwisixhobo.Enye inqaku eliye latsala ingqalelo enkulu kukuba ingaba i-E-MARKER chip iyafuneka kumgca wothumelo lweCC.Lo mgangatho wesigwebo yinkqubo yokusetyenziswa, ngaba okwangoku kuya kudlula i-3A?Ukuba ayidluli, awuyifuni.Umgca ukusuka ku-A ukuya ku-C, B ukuya ku-C kuxhomekeke ekubeni ufuna ukusebenzisa iprothokholi yokuTshaja ibhetri.Ukuba ufuna ukuyiphumeza, ungasebenzisa i-LDR6013.I-advanteji kukuba inokuqonda zombini ukutshaja kunye nokutshaja.Ukutshintshela idatha ukunqanda ingxaki ukuba ezinye iiadaptha ezingahambelani neBattery Charging protocol azikwazi ukuhlawulisa izixhobo ze-Apple.
