Rockchip idakhazikitsa chip RK838 chatsopano chochapira mwachangu, cholondola nthawi zonse, kugwiritsa ntchito magetsi otsika kwambiri, ndikudutsa satifiketi ya UFCS.

Mawu oyamba

Protocol chip ndi gawo lofunikira komanso lofunikira pa charger. Ili ndi udindo wolumikizana ndi chipangizo cholumikizidwa, chomwe chili chofanana ndi mlatho wolumikiza chipangizocho. Kukhazikika kwa chip cha protocol kumachita gawo lalikulu pazochitikira komanso kudalirika kwa kulipiritsa mwachangu.

Posachedwapa, Rockchip idakhazikitsa protocol chip RK838 yokhala ndi core Cortex-M0 core, yomwe imathandizira USB-A ndi USB-C kuthamangitsa madoko awiri, imathandizira PD3.1, UFCS ndi ma protocol osiyanasiyana othamangitsa mwachangu pamsika, ndi amatha kuzindikira Mphamvu yolipiritsa kwambiri ndi 240W, imathandizira ma voliyumu olondola kwambiri komanso kuwongolera kosalekeza komanso kugwiritsa ntchito magetsi otsika kwambiri.

Chithunzi cha RK838

Rockchip RK838 ndi chipangizo chothamangitsira mwachangu chomwe chimaphatikizira USB PD3.1 ndi protocol ya UFCS, yokhala ndi doko la USB-A ndi doko la USB-C, imathandizira kutulutsa kwapawiri kwa A + C, ndipo njira zonse ziwiri zimathandizira protocol ya UFCS. Nambala ya satifiketi ya UFCS: 0302347160534R0L-UFCS00034.

RK838 imatenga kamangidwe ka MCU, mkati imaphatikiza Cortex-M0 pachimake, 56K malo osungiramo zinthu zazikulu, 2K SRAM malo kuti azindikire PD ndi ma protocol ena ogwirizana, ndipo ogwiritsa ntchito amatha kuzindikira kusungirako kwama code angapo ndi ntchito zosiyanasiyana zoteteza.
Zikafika pakulipiritsa kwamphamvu kwambiri, mwachilengedwe sikungasiyanitsidwe ndi malamulo olondola kwambiri amagetsi. RK838 amathandiza nthawi zonse voteji linanena bungwe la 3.3-30V, ndipo akhoza kuzindikira mosalekeza thandizo panopa 0-12A. Pomwe nthawi zonse imakhala mkati mwa 5A, cholakwikacho chimakhala chochepera ± 50mA.

RK838 alinso anamanga-mu mabuku chitetezo ntchito, pakati pa CC1/CC2/DP/DM/DP2/DPM2 zikhomo onse amathandiza 30V kupirira voteji, amene angathe kuteteza kuonongeka mizere deta kuwononga mankhwala, ndi kuthandiza shutdown mofulumira linanena bungwe pambuyo overvoltage. . Chipchi chimakhalanso ndi chitetezo chowonjezera, chitetezo cha overvoltage, chitetezo cha undervoltage ndi chitetezo chotenthetsera kuti chitsimikizire kugwiritsidwa ntchito kotetezeka.
