Rockchip yatulutsa chip yatsopano ya RK838 yolipirira mwachangu, yokhala ndi kulondola kwamphamvu kwamagetsi, kugwiritsa ntchito mphamvu zochepa kwambiri, komanso yapambana satifiketi ya UFCS.

Mawu Oyamba

Chipu ya protocol ndi gawo lofunika kwambiri komanso lofunika kwambiri la charger. Ili ndi udindo wolankhulana ndi chipangizo cholumikizidwa, chomwe chili chofanana ndi mlatho wolumikiza chipangizocho. Kukhazikika kwa chipu ya protocol kumachita gawo lofunika kwambiri pakuwona ndi kudalirika kwa kuyatsa mwachangu.

Posachedwapa, Rockchip yatulutsa protocol chip RK838 yokhala ndi Cortex-M0 core yomangidwa mkati, yomwe imathandizira USB-A ndi USB-C dual-port fast charging, imathandizira PD3.1, UFCS ndi ma protocol osiyanasiyana odziwika bwino ochapira mwachangu pamsika, ndipo imatha kuzindikira Mphamvu yayikulu kwambiri yochapira ndi 240W, imathandizira voltage yokhazikika yolondola kwambiri komanso kuwongolera kwamagetsi kosalekeza komanso kugwiritsa ntchito mphamvu zochepa kwambiri.

Rockchip RK838

Rockchip RK838 ndi chip yofulumira yojambulira yomwe imaphatikiza USB PD3.1 ndi protocol core ya UFCS, yokhala ndi doko la USB-A ndi doko la USB-C, imathandizira kutulutsa kwa A+C kawiri, ndipo njira zonse ziwiri zimathandizira protocol ya UFCS. Nambala ya satifiketi ya UFCS: 0302347160534R0L-UFCS00034.

RK838 imagwiritsa ntchito kapangidwe ka MCU, imagwirizanitsa mkati mwake Cortex-M0 core, malo osungiramo flash okhala ndi mphamvu ya 56K, malo osungiramo ma flash a 2K SRAM kuti akwaniritse ma PD ndi ma protocol ena apadera, ndipo ogwiritsa ntchito amatha kusunga ma code ambiri komanso ntchito zosiyanasiyana zoteteza.
Ponena za kuyitanitsa mwachangu kwamphamvu kwambiri, mwachibadwa sikusiyana ndi malamulo amagetsi olondola kwambiri. RK838 imathandizira kutulutsa kwamagetsi kosasintha kwa 3.3-30V, ndipo imatha kupereka chithandizo chamagetsi chosasintha cha 0-12A. Mphamvu yosasintha ikafika mkati mwa 5A, cholakwikacho chimakhala chochepera ±50mA.

RK838 ilinso ndi ntchito zoteteza zomwe zimamangidwa mkati mwake, zomwe CC1/CC2/DP/DM/DP2/DP2 imayika zonse zomwe zimathandiza 30V kupirira magetsi, zomwe zingalepheretse kuti deta yowonongeka isawonongeke, komanso zimathandiza kutseka mwachangu kwa magetsi pambuyo pa magetsi ambiri. Chip iyi ilinso ndi chitetezo cha magetsi ambiri, chitetezo cha magetsi ambiri, chitetezo cha magetsi ochepa komanso chitetezo cha kutentha kwambiri kuti zitsimikizire kuti ikugwiritsidwa ntchito bwino.
