Ibisobanuro kuri DRV8842
DRV8842 itanga igisubizo cyimodoka ikomatanya kubicapiro, scaneri, nibindi bikoresho byikora.Igikoresho gifite umushoferi umwe wa H-ikiraro, kandi kigenewe gutwara moteri imwe ya DC, igiceri kimwe cya moteri ikomeza, cyangwa indi mitwaro.Ibisohoka bisohoka bigizwe na N-umuyoboro imbaraga MOSFETs yagizwe nka H-ikiraro.DRV8842 irashobora gutanga amashanyarazi agera kuri 5-A cyangwa 3.5-A ya RMS isohoka (hamwe no gushyushya neza kuri 24 V na 25 ° C).
Gutandukanya inyongeramusaruro kugirango wigenga kugenzura buri gice cya H-ikiraro gitangwa.
Imikorere yo guhagarika imbere itangwa kurinda birenze urugero, kurinda imiyoboro ngufi, gufunga amashanyarazi, no kurenza urugero.
TheDRV8842 iraboneka muri paki 28-pin ya HTSSOP hamwe na PowerPAD (Ibidukikije byangiza ibidukikije: RoHS & no Sb / Br).
Kubintu byose biboneka, reba ibyongeweho byongeweho kumpera yamakuru.
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
