Ibisobanuro kuri DRV8871
Ibikoresho bya DRV8871 bikoresha moteri ya DC ya moteri ya printer, ibikoresho, ibikoresho byinganda, nibindi bito bito.Ibintu bibiri byinjira byinjira bigenzura umushoferi wa H-ikiraro, kigizwe na N-umuyoboro wa N-MOSFETsthat irashobora kugenzura moteri ibyerekezo byombi hamwe na 3.6-Impinga yumuriro.Inyongeramusaruro irashobora kuba-ubugari bwahinduwe (PWM) kugirango igenzure umuvuduko wa moteri, ukoresheje guhitamo uburyo-bubora.Settingboth yinjiza hasi yinjira muburyo buke bwo gusinzira.
Ibikoresho bya DRV8871 bigezweho bigezweho-bigenzura imiyoboro idakoresha analogi ya voltage cyangwa rezistor yo hanze.Iki gisubizo gishya gikoresha igiciro gito, imbaraga-nke zo kwihanganira gushiraho ibihe bigezweho.Ubushobozi bwo kugabanya imiyoboro kurwego ruzwi birashobora kugabanya cyane sisitemu yingufu za sisitemu hamwe nubushobozi bwinshi bukenewe kugirango umuyaga uhoraho, cyane cyane kubitangira moteri no guhagarara.
Igikoresho kirinzwe byimazeyo amakosa hamwe nizunguruka ngufi, harimo munsi ya volvoltage (UVLO), kurenza urugero (OCP), hamwe nubushyuhe bukabije (TSD).Iyo ikosa ryakuweho, thedevice ihita ikomeza imikorere isanzwe.
1. Ni bande bakozi mu ishami rya R & D?Ni ubuhe bushobozi bwawe?
-R & D Umuyobozi: gutegura gahunda yigihe kirekire yikigo no gusobanukirwa icyerekezo cyubushakashatsi niterambere;Kuyobora no kugenzura ishami rishyira mubikorwa ingamba za sosiyete na gahunda ya R&D yumwaka;Kugenzura iterambere ryibicuruzwa no guhindura gahunda;Shiraho ibicuruzwa byiza byubushakashatsi niterambere, kugenzura no guhugura abakozi ba tekiniki bijyanye.
Umuyobozi wa R & D: kora ibicuruzwa bishya R & D hanyuma werekane ko bishoboka gahunda;Kugenzura no gucunga iterambere nubuziranenge bwakazi;Kora ubushakashatsi ku bicuruzwa bishya kandi utange ibisubizo bifatika ukurikije ibyo umukiriya asabwa mubice bitandukanye
Abakozi & gukusanya: gukusanya no gutondekanya amakuru yingenzi;Porogaramu ya mudasobwa;Gukora ubushakashatsi, ibizamini nisesengura;Tegura ibikoresho nibikoresho byo kugerageza, kugerageza no gusesengura;Andika amakuru yo gupima, gukora ibarwa no gutegura imbonerahamwe;Kora ubushakashatsi bwibarurishamibare
2. Niki gitekerezo cyawe cyo gukora ubushakashatsi nibitekerezo byiterambere?
- Igitekerezo cyibicuruzwa no guhitamo ibicuruzwa nibisobanuro byerekana ibicuruzwa nibishushanyo mbonera byumushinga no kugerageza ibicuruzwa bitezimbere no kwemeza isoko
