Rockchip tau tshaj tawm cov txheej txheem them nqi ceev ceev tshiab RK838, nrog rau qhov tseeb qhov tseeb tam sim no, kev siv hluav taws xob qis qis qis, thiab dhau UFCS ntawv pov thawj

Lus qhuab ntuas

Cov txheej txheem nti yog qhov tseem ceeb thiab tseem ceeb ntawm lub charger. Nws yog lub luag haujlwm rau kev sib txuas lus nrog cov cuab yeej txuas nrog, uas yog sib npaug rau tus choj txuas lub cuab yeej. Kev ruaj ntseg ntawm cov txheej txheem nti ua lub luag haujlwm txiav txim siab hauv kev paub dhau los thiab kev ntseeg siab ntawm kev them nyiaj ceev.

Tsis ntev los no, Rockchip tau tshaj tawm cov txheej txheem nti RK838 nrog lub Cortex-M0 core built-in, uas txhawb nqa USB-A thiab USB-C dual-chaw nres nkoj ceev them, txhawb PD3.1, UFCS thiab ntau yam kev them nyiaj ceev ceev ntawm lub khw, thiab tuaj yeem paub Lub zog them siab tshaj plaws yog 240W, txhawb nqa high-precision tsis tu ncua voltage thiab tswj tam sim no tsis tu ncua thiab ultra-tsawg standby zog noj.

Rockchip RK838

Rockchip RK838 yog cov txheej txheem them ceev ceev uas txuas nrog USB PD3.1 thiab UFCS raws tu qauv, nruab nrog USB-A chaw nres nkoj thiab USB-C chaw nres nkoj, txhawb nqa A + C dual tso zis, thiab ob txoj kev txhawb nqa UFCS raws tu qauv. UFCS daim ntawv pov thawj: 0302347160534R0L-UFCS00034.

RK838 txais yuav MCU architecture, sab hauv koom ua ke Cortex-M0 core, 56K loj-muaj peev xwm flash chaw cia, 2K SRAM chaw kom paub PD thiab lwm yam kev cai lij choj, thiab cov neeg siv tuaj yeem paub ntau txoj cai tswj hwm thiab ntau yam kev cai tiv thaiv kev ua haujlwm.
Thaum nws los txog rau high-power fast charging, nws yog ib txwm inseparable los ntawm high-precision voltage kev cai. RK838 txhawb nqa qhov hluav taws xob tas li ntawm 3.3-30V, thiab tuaj yeem paub qhov kev txhawb nqa tam sim no ntawm 0-12A. Thaum qhov tam sim no tsis tu ncua nyob rau hauv 5A, qhov yuam kev tsawg dua ± 50mA.

RK838 kuj tseem muaj kev tiv thaiv kev ua haujlwm zoo, ntawm cov CC1 / CC2 / DP / DM / DP2 / DPM2 pins tag nrho cov kev txhawb nqa 30V tiv taus hluav taws xob, uas tuaj yeem tiv thaiv cov ntaub ntawv puas los ntawm kev ua rau cov khoom puas tsuaj, thiab txhawb kev kaw sai ntawm cov zis tom qab overvoltage. . Lub nti kuj tseem muaj kev tiv thaiv overcurrent, tiv thaiv overvoltage, kev tiv thaiv undervoltage thiab overheating tiv thaiv kom muaj kev nyab xeeb siv.
