Inkcazelo ye-DRV8842
I-DRV8842 ibonelela ngesisombululo esidityanisiweyo somqhubi wemoto kubashicileli, iiskena, kunye nezinye izixhobo zokusebenza ezizenzekelayo.Isixhobo sinomqhubi omnye we-H-bridge, kwaye senzelwe ukuqhuba enye imoto ye-DC, i-coil enye ye-stepper motor, okanye enye imithwalo.Ibhloko yomqhubi wemveliso iqulathe amandla e-N-channel MOSFETs aqwalaselwe njengebhulorho ye-H.I-DRV8842 inokubonelela nge-5-A peak okanye i-3.5-A ye-RMS yemveliso yangoku (kunye ne-heatsing efanelekileyo kwi-24 V kunye ne-25 ° C).
Igalelo elahlukileyo lokulawula ngokuzimeleyo isiqingatha ngasinye sebhulorho ye-H zinikezelwa.
Imisebenzi yokuvala yangaphakathi ibonelelwa ngokhuseleko oludlulayo, ukhuseleko lwesekethe emfutshane, ukuvalwa kwe-undervoltage, kunye nobushushu obugqithisileyo.
I-DRV8842 ifumaneka kwi-28-pin ye-HTSSOP package ene-PowerPAD (Eco-friendly: RoHS & no Sb/Br).
Kuzo zonke iipakethe ezikhoyo, jonga i-adendum enolandelelwano ekupheleni kwedatha.
1. Ngoobani abasebenzi kwisebe lakho le-R & D?Ziziphi iziqinisekiso zakho?
-R & D UMlawuli: yenza isicwangciso sexesha elide seR & D senkampani kwaye ubambe isikhokelo sophando kunye nophuhliso;Ukukhokela kunye nokulawula isebe le-r&d ukuphumeza isicwangciso se-r&d yenkampani kunye nesicwangciso sonyaka se-R&D;Lawula inkqubela phambili yophuhliso lwemveliso kwaye uhlengahlengise isicwangciso;Misela uphando lwemveliso egqwesileyo kunye neqela lophuhliso, uphicotho kunye noqeqesho olunxulumene nabasebenzi bobugcisa.
Umphathi we-R & D: yenza imveliso entsha ye-R & D isicwangciso kwaye ubonise ukwenzeka kwesicwangciso;Ukongamela kwaye ulawule inkqubela kunye nomgangatho womsebenzi we-r&d;Phanda ngophuhliso lwemveliso entsha kwaye ucebise izisombululo ezisebenzayo ngokweemfuno zabathengi kwiinkalo ezahlukeneyo
Abasebenzi be-R&d: ukuqokelela kunye nokusombulula iinkcukacha eziphambili;inkqubo yeKhompyutha;Ukuqhuba iimvavanyo, iimvavanyo kunye nohlalutyo;Lungisa izixhobo kunye nezixhobo zovavanyo, iimvavanyo kunye nohlalutyo;Ukurekhoda idatha yokulinganisa, yenza izibalo kwaye ulungiselele iitshathi;Yenza uphando lwamanani
2. Yintoni uphando lwakho lwemveliso kunye nombono wophuhliso?
-Umbono wemveliso kunye nokukhethwa kwemveliso kunye novavanyo lwenkcazo yemveliso kunye noyilo lwesicwangciso seprojekthi kunye novavanyo lwemveliso kunye nokuqinisekiswa kokuqaliswa kwintengiso
