Tsim USB hom c ceev ceev PD them cov khoom, cov kev paub tsim nyog

Peb txhua tus paub tias tus qauv USB hom C interface muaj 24 pIN taw, 12 PIN ntawm txhua sab.

1: Hauv cov khoom siv hluav taws xob them nyiaj, peb tsuas yog yuav tsum siv VBUS, GND, CC1, CC2, D+1, D+2, D-1, D+2. Cov pins no tuaj yeem siv tau, lwm yam RX, TX, SBU tus pins tsis xav tau, thiab tuaj yeem tso tawm. Txij li thaum peb muab cov khoom siv fais fab, muaj ntau tus pins uas tsis siv. Raws li cov chaw tsim khoom USB interface, peb kuj tau qhia sai sai USB TYPE C interfaces xws li 16-pin thiab 14-pin. Qee qhov USB HOM C interfaces tsuas muaj 6 tus PIN pins, thiab 5, thiab lwm yam., qee qhov tsis muaj CC tus pin, tsis muaj USB chaw nres nkoj nrog CC tus pin, peb txhais ko taw HOM C, yog USB HOM C plhaub USB interface, qhov no muaj nuj nqi. zoo ib yam li hom A thiab MICRO cov tsoos B interface muaj tib txoj haujlwm.

2, koj yuav tsum paub txog USB hom C PD them khoom, nws yog hloov los ntawm MOS, tsis muaj hluav taws xob tsis muaj zog.

Yog tias koj yog ib yam li peb tau hais saum toj no, lub charger nrog tus fake USB HOM C yam tsis muaj CC tus pin, lub zog hluav taws xob, lub tsheb charger, qhov no tsis nyob rau hauv qhov chaw.

PD them raws tu qauv Nws xav tau CC tus pin los sib txuas lus, kev sib txuas lus ntawm PD nti thiab xov tooj ntawm tes yog CC tus pin. Kuj tseem muaj PD charger, lub tsheb charger, mobile fais fab mov, thiab lwm yam PD charging raws tu qauv xav kom cov zis muaj MOS. Tom qab CC kev sib txuas lus, MOS tau qhib thiab cov zis tau qhib. Qhov no yog qhov voltage thiab tam sim no. Yog li thaum tsis muaj dab tsi txuas nrog, tsis muaj qhov ntsuas hluav taws xob ntawm USB HOM C interface, vim tias MOS tseem tsis tau qhib. PD nti yuav tsum sib txuas lus nrog lub xov tooj ntawm tes / khoom siv. Tom qab kev sib tuav tes ua tiav, cov zis hluav taws xob tau qhib.

3, usb hom c ceev ceev PD them cov khoom yuav tsum tau kuaj, nqa lub xov tooj txhua zaus?

Qhov no tsis yog li ntawd. Ib yam li QC ceev ceev, QC ceev them nqi kuaj board lossis QC ntsuas ntsuas yog siv hauv ntau lawm.

4, koj yuav tsum paub tias DFP thiab DRP txhais li cas.

DFP (Downstream Facing Port): Qhov chaw nres nkoj downlink tuaj yeem nkag siab tias yog Tus Tswv. DFP muab VBUS thiab tuaj yeem muab cov ntaub ntawv. Ib yam khoom siv DFP yog lub hwj chim adapter thiab lub tsheb charger vim nws ib txwm muab lub zog.

DRP (Dual Role Port): Dual Role Port. DRP tuaj yeem siv ua DFP (Host) lossis UFP (Device). Nws tseem tuaj yeem hloov pauv hloov pauv ntawm DFP thiab UFP. Ib yam khoom siv DRP yog lub khoos phis tawj (lub khoos phis tawj tuaj yeem siv los ua tus tswv tsev USB lossis ua cov khoom siv them nyiaj (Apple's tshiab MAC Book Air)), lub xov tooj ntawm tes uas siv OTG (lub xov tooj ntawm tes tuaj yeem siv los ua cov khoom siv them nyiaj thiab nyeem cov ntaub ntawv, Nws tseem tuaj yeem siv los ua tus tswv tsev los muab lub zog rau lwm yam khoom siv lossis nyeem U disk cov ntaub ntawv.) Lub zog hluav taws xob (kev tso tawm thiab kev them nqi tuaj yeem dhau los ntawm USB Hom-C, uas yog, qhov chaw nres nkoj tuaj yeem tawm lossis them nqi. ).
