Zithunzi za ULN2003A
Zipangizo za ULx200xA ndi zamphamvu kwambiri, zamtundu wa Darlington transistor wamakono.Iliyonse imakhala ndi ma NPN awiri awiri a Darlington asanu ndi awiri omwe amakhala ndi zotulutsa zamphamvu kwambiri zokhala ndi ma diode osavuta a cathode osinthira katundu wolowera.
Mtengo wamakono wa gulu limodzi la Darlington ndi 500 mA.Ma pairs a Darlington amatha kufananizidwa ndi luso lamakono.Mapulogalamuwa akuphatikiza madalaivala, ma hammerdrivers, madalaivala a nyali, madalaivala owonetsera (LED ndi kutulutsa gasi), madalaivala amizere, ndi ma buffers omveka.Chithunzi cha SLRS023Zithunzi za SN75468 ndi SN75469zipangizo
Chipangizo cha ULN2002A chidapangidwa kuti chizigwiritsidwa ntchito ndi 14-V mpaka 25-V PMOS zida.Kulowetsa kulikonse kwa chipangizochi kumakhala ndi diode ya Zener ndi resistor mu mndandanda kuti muzitha kuwongolera zomwe zilipo panopa mpaka malire otetezeka.Zipangizo za ULx2003A zili ndi 2.7-kΩ zotsamira zoyambira pagulu lililonse la Darlington kuti zizigwira ntchito mwachindunji ndi zida za TTL kapena 5-V CMOS.
Zipangizo za ULx2004A zili ndi 10.5-kΩ series resistor kuti zilole kugwira ntchito molunjika kuchokera ku zipangizo za CMOS zomwe zimagwiritsa ntchito magetsi a 6 V mpaka 15 V. Zomwe zimafunikira pakalipano za ULx2004Adevice zili pansi pa zida za ULx2003A, ndipo magetsi ofunikira ndi ocheperapo. zomwe zimafunidwa ndi chipangizo cha ULN2002A.
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
