Ihe mgbawa protocol bụ ihe dị mkpa na akụkụ dị mkpa nke chaja. Ọ bụ ya na-ahụ maka iji ngwaọrụ ejikọrọ na-ekwurịta okwu, nke ya na akwa mmiri jikọtara ngwaọrụ ahụ. Nkwụsi ike nke mgbawa protocol na-arụ ọrụ dị mkpa na ahụmahụ na ntụkwasị obi nke nchaji ngwa ngwa.

N'oge na-adịbeghị anya, Rockchip kwalitere mgbawa protocol RK838 nwere Cortex-M0 core arụnyere, nke na-akwado USB-A na USB-C dual-port chaja ngwa ngwa, na-akwado PD3.1, UFCS na usoro dị iche iche na-ebufe ngwa ngwa n'ahịa, na nwere ike ịghọta na ike chaja kacha elu bụ 240W, na-akwado voltaji dị elu na-adịgide adịgide na njikwa ugbu a na njikwa ike dị ala dị ala.

Rockchip RK838

Rockchip RK838 bụ mgbawa protocol chaja ngwa ngwa nke na-ejikọta USB PD3.1 na UFCS protocol core, nke nwere ọdụ USB-A na ọdụ ụgbọ mmiri USB-C, na-akwado mmepụta abụọ A + C, na ọwa abụọ ahụ na-akwado UFCS protocol. UFCS nọmba akwụkwọ: 0302347160534R0L-UFCS00034.

RK838 na-agbaso ụkpụrụ MCU, na-ejikọta Cortex-M0 isi, 56K nnukwu nchekwa nchekwa nchekwa, ohere 2K SRAM iji ghọta PD na usoro iwu ndị ọzọ, na ndị ọrụ nwere ike ịghọta nchekwa koodu multi-protocol na ọrụ nchebe omenala dị iche iche.
A bịa n'ịchaji ngwa ngwa ike dị elu, ọ bụ ihe a na-apụghị ikewapụ na ụkpụrụ voltaji dị elu. RK838 na-akwado mmepụta voltaji mgbe niile nke 3.3-30V, ma nwee ike ịghọta nkwado nke 0-12A mgbe niile. Mgbe oge dị ugbu a dị n'ime 5A, njehie ahụ erughị ± 50mA.

RK838 nwekwara arụ ọrụ nchebe zuru oke, n'ime nke CC1 / CC2 / DP / DM / DP2 / DPM2 na-akwado 30V na-eguzogide voltaji, nke nwere ike igbochi ahịrị data mebiri emebi site na imebi ngwaahịa, ma na-akwado nkwụsị ngwa ngwa nke mmepụta mgbe oke ọkụ. . Ihe mgbawa ahụ nwekwara ihe nchebe na-agafe agafe, nchebe overvoltage, nchebe n'okpuru voltaji na nchebe ikpo ọkụ iji hụ na iji ya mee ihe n'enweghị nsogbu.
