Tsanangudzo yeULN2003A
Iyo ULx200xA zvishandiso zvine high-voltage, yakakwirira-ikozvino Darlington transistor arrays.Imwe neimwe ine nomwe NPN Darlington pairi inoratidzira yakakwirira-voltage inobuda neyakajairwa-cathode clamp diode yekuchinja inductive mitoro.
Iyo yekuunganidza-ikozvino chiyero cheimwe Darlington pair ndeye 500 mA.Iyo Darlington pairs inogona kufananidzwa kune yakakwirira ikozvino kugona.Zvishandiso zvinosanganisira madhiraivha, sando, madhiraivha emarambi, madhiraivha ekuratidzira (LED uye gasi rinobuda), madhiraivha emitsara, uye logic buffers.Kune 100-V (zvimwe zvinochinjika) shanduro dzeULx2003A zvishandiso, onaSLRS023data sheet yeSN75468 uye SN75469devices.
Iyo ULN2002A mudziyo wakagadzirirwa chaizvo kushandiswa ne14-V kusvika25-V PMOS zvishandiso.Kupinza kwega kwega kwemudziyo uyu kune Zener diode uye resistor munhevedzano kudzora yekupinda ikozvino kune yakachengeteka muganhu.Iyo ULx2003A midziyo ine 2.7-kΩ yakatevedzana base resistor kune yega yega Darlington pair yekushanda zvakananga neTTL kana 5-V CMOS zvishandiso.
Zvigadzirwa zveULx2004A zvine 10.5-kΩ series base resistor kubvumira kushanda zvakananga kubva kuCMOS zvishandiso zvinoshandisa magetsi ekupa 6 V kusvika ku15 V. Ikozvino inodiwa yekupinda yeULx2004Adevice iri pasi peiyo ULx2003A zvishandiso, uye magetsi anodiwa ari pasi pe. iyo inodiwa neULN2002A mudziyo.
1. Ndivanaani vashandi mudhipatimendi rako reR & D?Ndezvipi zvidzidzo zvako?
-R & D Mutungamiriri: gadzira chirongwa chekambani chenguva refu R & D uye ubate gwara rekutsvaga nekusimudzira;Tungamira uye tarisa r&d dhipatimendi kuti iite kambani r&d zano uye yegore R&D chirongwa;Dzora kufambira mberi kwekugadzirwa kwechigadzirwa uye gadzirisa chirongwa;Gadzira yakanakisa chigadzirwa chekutsvagisa uye timu yekusimudzira, yekuongorora uye yekudzidziswa ine chekuita nehunyanzvi vashandi.
R & D Maneja: gadzira chigadzirwa chitsva R & D kuronga uye kuratidza kugona kwechirongwa;Tarisa uye gadzirisa kufambira mberi uye kunaka kwer&d basa;Tsvagurudza kugadzirwa kwechigadzirwa chitsva uye kurudzira mhinduro dzinoshanda zvinoenderana nezvinodiwa nevatengi munzvimbo dzakasiyana
Vashandi veR&d: unganidza uye gadzirisa data rakakosha;Computer programming;Kuita zviedzo, bvunzo uye ongororo;Gadzirira zvinhu uye zvishandiso zvekuyedza, bvunzo uye ongororo;Rekodha data yekuyera, ita kuverenga uye gadzira machati;Ita ongororo dzenhamba
2. Ndeipi yako chigadzirwa tsvakurudzo uye budiriro pfungwa?
-Kufunga kwechigadzirwa uye sarudzo yechigadzirwa pfungwa uye yekuongorora tsanangudzo yechigadzirwa uye dhizaini dhizaini uye kusimudzira chigadzirwa kuyedzwa uye kusimbiswa kwekutanga kumusika.
