Mgbawa protocol bụ akụkụ dị mkpa ma dị mkpa nke chaja. Ọ bụ ya na-ahụ maka ịkparịta ụka na ngwaọrụ ejikọtara, nke yiri akwa mmiri na-ejikọ ngwaọrụ ahụ. Nkwụsi ike nke mgbawa protocol na-arụ ọrụ dị mkpa na ahụmịhe na ntụkwasị obi nke chaja ngwa ngwa.

N'oge na-adịbeghị anya, Rockchip wepụtara mgbawa protocol RK838 nwere Cortex-M0 core arụnyere n'ime ya, nke na-akwado USB-A na USB-C dual-port chaja ngwa ngwa, na-akwado PD3.1, UCFS na usoro chaja ngwa ngwa dị iche iche n'ahịa, ma nwee ike ịghọta Ike chaja kachasị elu bụ 240W, na-akwado voltaji na-agbanwe agbanwe na njikwa ugbu a na-agbanwe agbanwe yana oriri ike dị ala nke ukwuu.

Rockchip RK838

Rockchip RK838 bụ mgbawa protocol chaja ngwa ngwa nke na-ejikọta isi protocol USB PD3.1 na UGCS, nke nwere ọdụ ụgbọ USB-A na ọdụ ụgbọ USB-C, na-akwado mmepụta abụọ A+C, ọwa abụọ ahụ na-akwado protocol UGCS. Nọmba asambodo UGCS: 0302347160534R0L-UFCS00034.

RK838 na-anabata usoro MCU, na-ejikọta isi Cortex-M0 n'ime ya, oghere nchekwa flash nwere ikike 56K buru ibu, oghere 2K SRAM iji mezuo PD na usoro ndị ọzọ nwere ikike, ndị ọrụ nwekwara ike ime nchekwa koodu protocol dị iche iche na ọrụ nchekwa omenala dị iche iche.
Maka ịchaji ngwa ngwa dị elu, ọ bụ ihe a na-apụghị ikewapụ na nhazi voltaji dị elu. RK838 na-akwado mmepụta voltaji na-adịgide adịgide nke 3.3-30V, ma nwee ike nweta nkwado ugbu a na-adịgide adịgide nke 0-12A. Mgbe oge ugbu a na-adịgide adịgide dị n'ime 5A, njehie ahụ erughị ±50mA.

RK838 nwekwara ọrụ nchekwa zuru oke arụnyere n'ime ya, gụnyere ihe mkpuchi CC1/CC2/DP/DM/DP2/DPM2 niile na-akwado voltaji 30V, nke nwere ike igbochi ahịrị data mebiri emebi imebi ngwaahịa, ma kwado mmechi ngwa ngwa nke mmepụta mgbe voltaji karịrị akarị gasịrị. Chip ahụ nwekwara nchekwa overcurrent arụnyere n'ime ya, nchekwa overvoltaji, nchekwa undervoltaji na nchekwa overheating iji hụ na ejiri ya nke ọma.
