Cov chaw quiescent ntawm cov USB yam-C muaj cov nyhuv
Tom qab teevYam-C USBinterface, phau computers, tes ntse thiab ntsiav tshuaj launched, yam-C USB kuj yog ib lub npe kub; ntawm no li yuav siv tau rau ob leeg them, tab sis kuj mus txuas yam-C Interface peripherals.
Qhov kev hloov no ntau zog rau qhov yam-C AC / DC charger thiab cov coupons qhov thov cov khoom muaj nqis, vim yam-C connector muaj ib user-friendly reversible muaj nuj nqi. Tseem ceeb ntau kis mas yam-C charger thiab them cov khoom muaj nqis muaj feem ntau yuav muaj ntau yam laptops, ntse tes, ntsiav tshuaj xyuas hauv computer thiab lwm yam khoom siv hauv ntau
Interestingly, cov chargers thiab them cov khoom muaj nqis configurations rau lawv teev tiam yam-A thiab tsis ntau ntau. Tiam sis, ib co designers muaj charger zaum ib txoj tseem ceeb, thiab uas yog vim tus ntxiv yam-C Circuit Court, yam-C connector overlook yuav xav paub txog ntxiv zog. Thiab itand #39; s tus era tsis yog cov USB2.0 D + / D-qhov zoo sib xws.
Yam-C tas configure cov channel (CC) no ntawm cov pins uas muaj ntsaws cov, txuas nrog lub ntsiab lus ntawm qhov chaw nres nkoj, thiab thaum twg koj xav tau ib tug ntau dua tso zis voltage muaj ntxiv zog kis (PD) sib. Cov nta ntaub ntxiv yuav tsum muaj ntau integrated circuits (/ Hmong IC), uas yuav lawm haus li tam sim no. Thaum nimno, muaj ntau ntau yam-C hais haum raws li ib tug tub ntxhais microcontroller (MCU), thiab yuav haus cov dej muaj ntau dua quiescent tam sim no (IQ), tiam sis cov chaw feem ntau nyob rau hauv lub chav milliamps.
Txawm li ntawd los, tam sim no kev noj ntxiv yuav tau muaj tej yam tsis zoo ntawm cov hwjchim standby noj, thiab rau lub hwj huam efficiency tseeb kev AC / DC adapter (CoC) II hoob version 5 muaj tsawg tshaj li uas 75mW standby zog noj - qhov no yuav tsis tau qhab after yooj yim. Tas, yog tus them Po muaj yam-C tswj Circuit Court, cov chaw nyob nraum zoov generated txawm tias ntawm phaum tau hla siv roj teeb uas khiav.
Lawm downstream ports (DFP) xws li tsim yuav cuag tus IQ qis li ib lub hom phiaj loj tsim. Yuav tau optimized hom qauv siv rau kev noj tam sim no nyob rau hauv cov mA ntau yam. Piv txwv, TPS25810 yam-C DFP xws li thaum tsis ntaus txuas nrog rau kev noj tam sim no uas tsis tau muaj 0.7μA (typ). Qhov no yuav pab kom cov AC / DC adapter efficiency tuaj lub efficiency yuav tsum tau cov kev cai, thiab yuav xyuas kom meej tias ib tug niam tij charged muaj ib nyuag cia ntev ntev.
Vim paub ntau USB yam-C xws li tsim yuav siv tus IQ qis, AC / DC charger designers tsis tau ntxiv tiv thaiv circuitry tej nyiaj uas standby faiv fab tso cai. Siv cov uas tsis muaj IQ xws li them cov khoom muaj nqis yuav zoo cas sim haum lawv xwb cia sij hawm ua sij muab ib cov kev zoo.
