Ijambo ryibanze
Chip protocole ni ingenzi kandi igice cyingenzi cya charger. Irashinzwe kuvugana nigikoresho cyahujwe, gihwanye nikiraro gihuza igikoresho. Ihame rya protocole chip igira uruhare rukomeye muburambe no kwizerwa kwishyurwa byihuse.
Vuba aha, Rockchip yashyize ahagaragara protokol chip RK838 yubatswe muri Cortex-M0 yubatswe, ishyigikira USB-A na USB-C ibyuma byihuta byihuta byishyurwa, ishyigikira PD3.1, UFCS hamwe na protocole zitandukanye zihuta zishyurwa kumasoko, kandi irashobora kumenya imbaraga zumuriro mwinshi ni 240W, zishyigikira ingufu zidasanzwe kandi zihoraho hamwe no gukoresha ingufu zidasanzwe.
Rockchip RK838
Rockchip RK838 ni chip yihuta yo kwishyiriraho protocole ihuza USB PD3.1 na UFCS protocole yibanze, ifite icyambu cya USB-A hamwe nicyambu cya USB-C, ishyigikira ibyasohotse A + C, kandi iyo miyoboro yombi ishyigikira protocole ya UFCS. Icyemezo cya UFCS nimero: 0302347160534R0L-UFCS00034.
RK838 ikoresha ubwubatsi bwa MCU, imbere ihuza intangiriro ya Cortex-M0, 56K nini yububiko bunini bwa flash ububiko, umwanya wa 2K SRAM kugirango tumenye PD hamwe nandi ma protocole yihariye, kandi abayikoresha barashobora kumenya ububiko bwa kode-protocole hamwe nibikorwa bitandukanye byo kurinda ibicuruzwa.
Iyo bigeze kumashanyarazi yihuta cyane, mubisanzwe ntibishobora gutandukana numuyoboro mwinshi wa voltage. RK838 ishyigikira voltage ihoraho ya 3.3-30V, kandi irashobora kubona inkunga ihoraho ya 0-12A. Iyo imiyoboro ihoraho iri muri 5A, ikosa riri munsi ya 50mA.
RK838 kandi yubatswe mubikorwa byuzuye byo kurinda, muribyo CC1 / CC2 / DP / DM / DP2 / DPM2 pin zose zishyigikira 30V zihanganira voltage, zishobora gukumira neza imirongo yangiritse kwangiza ibicuruzwa, kandi igashyigikira ihagarikwa ryihuse ryibicuruzwa nyuma yumuriro mwinshi. Chip kandi yubatswe mu kurinda birenze urugero, kurinda ingufu zirenga, kurinda amashanyarazi no kurinda ubushyuhe bukabije kugirango ikoreshwe neza.
