Incazelo ye-DRV8871
Idivayisi ye-DRV8871 iwumshayeli wemoto oyi-brushed-DC wamaphrinta, izinto zikagesi, okokusebenza kwezimboni, neminye imishini emincane.Okokufaka okunengqondo okubili kulawula umshayeli we-H-bridge, ohlanganisa ama-MOSFET ama-N-channel amane akwazi ukulawula amamotho kabili afinyelela ku-3.6-A inani eliphakeme lamanje.Okokufaka kungenziwa i-bepulse-width modulated (PWM) ukuze kulawulwe isivinini semoto, kusetshenziswa ukukhetha kwezindlela zamanje zokubola.Ukusetha kokubili okokufaka kuphansi kungena kumodi yokulala enamandla aphansi.
Idivayisi ye-DRV8871 inomjikelezo wokulawula wamanje othuthukisiwe ongasebenzisi ireferensi kagesi we-analog noma isimelaphi senzwa yangaphandle.Lesi sixazululo senoveli sisebenzisa isivimbeli esijwayelekile esinezindleko eziphansi, esinamandla aphansi ukusetha umkhawulo wamanje.Ikhono lokubeka umkhawulo wamanje ezingeni elaziwayo linganciphisa ngokuphawulekayo izimfuneko zamandla esistimu namandla enqwaba adingekayo ukuze kugcinwe i-voltage ezinzile, ikakhulukazi yezimo ze-motor startupa kanye nezimo zokudayisa.
Idivayisi ivikelwe ngokugcwele kumaphutha namasekhethi amafushane, okuhlanganisa i-undervoltage(UVLO), i-overcurrent (OCP), ne-overtemperature (TSD).Uma isimo sephutha sisusiwe, idivayisi iqala kabusha ngokuzenzakalelayo ukusebenza okujwayelekile.
1. Obani abasebenzi bomnyango wakho we-R & D?Yiziphi iziqu zakho?
-R & D Umqondisi: yenza uhlelo lwesikhathi eside lwe-R & D lwenkampani futhi babambe isiqondiso socwaningo nentuthuko;Qondisa futhi uqondise umnyango we-r&d ukuze usebenzise isu le-r&d lenkampani kanye nohlelo lonyaka lwe-R&D;Lawula inqubekelaphambili yokuthuthukiswa komkhiqizo futhi ulungise uhlelo;Misa ithimba locwaningo lomkhiqizo elihle kakhulu nelokuthuthukisa, abacwaningi mabhuku kanye nokuqeqeshwa okuhlobene nabasebenzi bezobuchwepheshe.
Umphathi we-R & D: yenza uhlelo olusha lwe-R & D futhi ubonise ukuthi kungenzeka uhlelo;Ukugada nokuphatha inqubekelaphambili kanye nekhwalithi yomsebenzi we-r&d;Cwaninga ukuthuthukiswa komkhiqizo omusha futhi uphakamise izixazululo ezisebenzayo ngokuvumelana nezidingo zamakhasimende emikhakheni ehlukene
Abasebenzi be-R&d: baqoqa futhi balungise idatha ebalulekile;Uhlelo lwekhompyutha;Ukwenza izivivinyo, izivivinyo kanye nokuhlaziya;Lungiselela izinto zokwakha kanye nezinto zokusebenza zokuhlola, izivivinyo nokuhlaziya;Rekhoda idatha yokulinganisa, yenza izibalo futhi ulungiselele amashadi;Yenza izinhlolovo zezibalo
2. Uthini umbono wakho wocwaningo nokuthuthukiswa komkhiqizo?
- Ukwakhiwa komkhiqizo kanye nomqondo wokukhethwa komkhiqizo kanye nokuhlolwa kwencazelo yomkhiqizo kanye nomklamo wepulani yephrojekthi kanye nokuthuthukiswa kokuhlolwa komkhiqizo kanye nokwethulwa kokuqinisekisa emakethe
