Rockchip tau tshaj tawm lub nti tshiab them ceev ceev RK838, nrog rau qhov tseeb tam sim no siab, kev siv hluav taws xob tsawg heev, thiab tau dhau daim ntawv pov thawj UFCS.

Lus Qhia Ua Ntej

Lub protocol chip yog ib feem tseem ceeb thiab tsis tuaj yeem tsis tau ntawm lub charger. Nws yog lub luag haujlwm rau kev sib txuas lus nrog lub cuab yeej txuas nrog, uas zoo ib yam li tus choj txuas lub cuab yeej. Qhov ruaj khov ntawm lub protocol chip ua lub luag haujlwm tseem ceeb hauv kev paub thiab kev ntseeg siab ntawm kev them ceev.

Tsis ntev los no, Rockchip tau tsim ib lub protocol chip RK838 nrog lub Cortex-M0 core uas ua rau hauv, uas txhawb nqa USB-A thiab USB-C dual-port fast charging, txhawb nqa PD3.1, UFCS thiab ntau yam mainstream fast charging protocols hauv khw, thiab tuaj yeem paub tias lub zog them siab tshaj plaws yog 240W, txhawb nqa high-precision constant voltage thiab constant current control thiab ultra-low standby power consumption.

Rockchip RK838

Rockchip RK838 yog lub nti them ceev ceev uas sib xyaw ua ke USB PD3.1 thiab UFCS protocol core, nruab nrog lub chaw nres nkoj USB-A thiab lub chaw nres nkoj USB-C, txhawb nqa A + C dual output, thiab ob qho channel txhawb nqa UFCS protocol. UFCS daim ntawv pov thawj tus lej: 0302347160534R0L-UFCS00034.

RK838 siv MCU architecture, sab hauv muaj Cortex-M0 core, 56K qhov chaw cia khoom loj, 2K SRAM qhov chaw kom paub txog PD thiab lwm yam proprietary protocols, thiab cov neeg siv tuaj yeem paub txog ntau-protocol code cia thiab ntau yam kev tiv thaiv kev cai.
Thaum nws los txog rau kev them ceev ceev uas muaj zog heev, nws yog qhov tsis sib cais ntawm kev tswj hwm qhov hluav taws xob siab. RK838 txhawb nqa qhov hluav taws xob tas li ntawm 3.3-30V, thiab tuaj yeem ua tiav qhov kev txhawb nqa tam sim no ntawm 0-12A. Thaum qhov tam sim no tas li nyob hauv 5A, qhov yuam kev tsawg dua ± 50mA.

RK838 kuj muaj kev tiv thaiv ua tiav, ntawm cov CC1 / CC2 / DP / DM / DP2 / DPM2 pins txhua tus txhawb nqa 30V withstand voltage, uas tuaj yeem tiv thaiv cov kab ntaub ntawv puas tsuaj los ntawm kev ua rau cov khoom puas tsuaj, thiab txhawb kev kaw sai ntawm cov zis tom qab overvoltage. Lub nti kuj muaj kev tiv thaiv overcurrent, overvoltage tiv thaiv, undervoltage tiv thaiv thiab overheating tiv thaiv kom ntseeg tau tias siv tau zoo.
