Zithunzi za DRV8842
DRV8842 imapereka njira yophatikizira yoyendetsa galimoto ya osindikiza, ma scanner, ndi zida zina zamagetsi.Chipangizocho chili ndi dalaivala m'modzi wa H-bridge, ndipo cholinga chake ndi kuyendetsa galimoto imodzi ya DC, coil imodzi ya stepper motor, kapena katundu wina.Chotchinga cha driver chili ndi mphamvu ya N-channel MOSFETs opangidwa ngati H-mlatho.DRV8842 imatha kupereka mpaka 5-A pachimake kapena 3.5-A RMS yotulutsa pano (ndi heatsinking yoyenera pa 24 V ndi 25 ° C).
Zolowera zosiyana zowongolera pawokha theka lililonse la H-mlatho zimaperekedwa.
Ntchito zotsekera mkati zimaperekedwa kuti zitetezeke mopitilira muyeso, chitetezo chachifupi, kutseka kwamagetsi, komanso kutentha kwambiri.
TheDRV8842 ikupezeka mu phukusi la HTSSOP la mapini 28 okhala ndi PowerPAD (Eco-friendly: RoHS & no Sb/Br).
Pamaphukusi onse omwe alipo, onani chowonjezera chomwe chili kumapeto kwa ndandanda.
1. Kodi ogwira ntchito m'dipatimenti yanu ya R & D ndi ndani?Kodi ziyeneretso zanu ndi zotani?
-R & D Mtsogoleri: pangani dongosolo la nthawi yayitali la R & D ndikumvetsetsa momwe kafukufuku ndi chitukuko;Kuwongolera ndi kuyang'anira dipatimenti ya r&d kuti ikwaniritse njira zamakampani ndi mapulani apachaka a R&D;Kuwongolera kupita patsogolo kwa chitukuko cha mankhwala ndikusintha dongosolo;Khazikitsani gulu labwino kwambiri la kafukufuku wazinthu ndi chitukuko, kufufuza ndi kuphunzitsa ogwira ntchito zaukadaulo.
Woyang'anira R & D: pangani mankhwala atsopano a R & D ndikuwonetsa kuthekera kwa dongosolo;Kuyang'anira ndi kuyang'anira momwe ntchito ya R&d ikuyendera;Fufuzani zachitukuko chazinthu zatsopano ndikupereka mayankho ogwira mtima malinga ndi zomwe makasitomala amafuna m'magawo osiyanasiyana
Ogwira ntchito ndi R&d: sonkhanitsani ndikusankha zofunikira;Mapulogalamu apakompyuta;Kuyesa, kuyesa ndi kusanthula;Konzani zida ndi zida zoyeserera, zoyeserera ndi kusanthula;Lembani deta yoyezera, pangani mawerengedwe ndikukonzekera ma chart;Chitani kafukufuku wamawerengero
2. Kodi lingaliro lanu la kafukufuku ndi chitukuko ndi chiyani?
- Lingaliro lazinthu ndi kusankha kwazinthu ndikuwunika tanthauzo lazinthu ndi kapangidwe ka pulani ya projekiti ndi kuyezetsa kwachitukuko ndikutsimikizira kukhazikitsidwa kwa msika
