Incazelo ye-DRV8842
I-DRV8842 ihlinzeka ngesixazululo esihlanganisiwe somshayeli wemoto wamaphrinta, izikena, nezinye izinhlelo zokusebenza zemishini ezenzakalelayo.Idivayisi inomshayeli oyedwa we-H-bridge, futhi ihloselwe ukushayela injini eyodwa ye-DC, ikhoyili eyodwa ye-stepper motor, noma eminye imithwalo.Ibhulokhi yomshayeli okukhiphayo iqukethe ama-MOSFET wamandla wesiteshi se-N amiswe njengebhuloho le-H.I-DRV8842 inganikeza ukufika ku-5-A peak noma 3.5-A RMS yamanje yokuphumayo (nge-heatsing efanele ku-24 V kanye no-25°C).
Okufakiwe okuhlukene kokulawula ngokuzimele ingxenye ngayinye yebhuloho le-H kunikezwa.
Imisebenzi yokuvala shaqa yangaphakathi ihlinzekelwe ukuvikela okudlulele, ukuvikela isiyingi esifushane, ukuvala i-undervoltage, kanye nezinga lokushisa elidlulele.
I-DRV8842 itholakala kuphakheji ye-HTSSOP yamaphini angu-28 ene-PowerPAD (Eco-friendly: RoHS & no Sb/Br).
Kuwo wonke amaphakheji atholakalayo, bheka isengezo esihlelekayo ekugcineni kwedatha.
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
