Tshiab Thiab Orignal Drv11873pwpr Intergrated Circuit Court Ic Chip

luv luv piav qhia:

DRV11873 yog peb-theem, tsis muaj lub cev muaj zog tsav tsheb nrog lub zog MOSFETs nrog lub peev xwm tsav tam sim no mus txog 1.5-A txuas ntxiv thiab 2-A ncov.DRV11873 tshwj xeeb yog tsim los rau cov kiv cua tsav daim ntawv thov nrog lub suab qis thiab qis sab nraud suav nrog.DRV11873 muaj built-in overcurrent tiv thaiv tsis muaj lwm yam tam sim no xav tau resistor.Lub synchronous rectification hom kev ua haujlwm ua tiav kev ua haujlwm tau zoo rau kev siv tsav tsheb.DRV11873 outputs FG thiab RD los qhia txog lub cev muaj zog nrog qhib-drain tso zis.150 ° sensorless BEMF tswj tswv yim yog siv rau peb-theem lub cev muaj zog.DRV11873 muaj nyob rau hauv cov thermally-npaum 16-pin TSSOP pob.Kev ua haujlwm kub yog teev los ntawm -40 ° C txog 125 ° C.

Taw qhia

Cov maub los yog cov khoom siv hais kom hloov cov xaim ntawm lub ntsiab Circuit Court lossis tswj Circuit Court thiab hloov cov nqi tiv thaiv hauv Circuit Court hauv kev txiav txim siab ua ntej los tswj kev pib, tswj ceev, nres thiab thim rov qab ntawm lub cev muaj zog.Nws yog tsim los ntawm cov kev pab cuam txee, kev qhia ntawv sau npe, kev qhia decoder, lub sij hawm lub tshuab hluav taws xob thiab kev tswj xyuas kev ua haujlwm, uas yog lub "kev txiav txim siab lub cev" los tawm cov lus txib, piv txwv li, los tswj thiab tswj kev ua haujlwm ntawm tag nrho lub computer system.

Cov kev faib loj

Cov maub los tau muab faib ua ib qho kev sib xyaw ua ke ntawm kev sib xyaw ua ke thiab microprogram maub los, thiab txhua tus ntawm ob tus tswj hwm nws tus kheej muaj zog thiab tsis muaj zog.Tus tsim ntawm combinatorial logic maub los yog teeb meem thiab nyuaj, thiab thaum tsim tiav, nws tsis tuaj yeem hloov kho lossis nthuav dav, tab sis nws ceev ceev.Lub microprogram maub los yooj yim rau kev tsim, cov qauv yooj yim, nws yooj yim los hloov lossis nthuav dav, thiab kev ua haujlwm ntawm kev hloov kho lub tshuab kev qhia tsuas yog xav kom rov ua dua cov microprogram sib xws;Txhawm rau ntxiv cov lus qhia tshuab, tsuas yog ntxiv microprogram rau lub cim xeeb tswj, txawm li cas los xij, los ntawm kev ua tiav microprogram.Qhov kev sib piv tshwj xeeb yog raws li hauv qab no: Lub combinatorial logic maub los, tseem hu ua hard wiring controller, yog tsim los ntawm cov logic circuits thiab tso siab rau tag nrho cov khoom siv kom ua tiav cov haujlwm ntawm cov lus qhia.

Nws ua haujlwm li cas

Electromagnetic chuck maub los: ac voltage 380V tom qab transformer phaw, rectifier rau hauv 110V DC los ntawm kev tswj cov cuab yeej rau hauv chuck lub sijhawm no lub chuck yog magnetized, demagnetization los ntawm qhov rov qab voltage Circuit Court, tus maub los kom ua tiav demagnetization muaj nuj nqi.

Access Controller: Tus tswj xyuas kev nkag mus ua haujlwm hauv ob hom.Ib qho yog hom tshuaj xyuas, thiab lwm qhov yog hom kev lees paub.Hauv hom kev saib xyuas, tus maub los txuas ntxiv xa cov lus nug rau tus nyeem ntawv thiab tau txais cov lus teb los ntawm tus nyeem ntawv.Cov qauv no tseem nyob mus txog thaum tus nyeem ntawv paub txog daim npav.Thaum tus neeg nyeem daim npav paub txog daim npav, daim npav nyeem ntawv ua cov lus teb sib txawv rau tus tswj xyuas cov lus txib, hauv cov lus teb no, tus nyeem ntawv daim npav xa cov ntawv nyeem daim npav nrog cov ntaub ntawv nkag mus rau tus tswj kev nkag, kom tus tswj xyuas nkag nkag mus rau hauv cov ntawv nyeem. hom kev paub.Nyob rau hauv hom kev lees paub ntawm tus tswj kev nkag mus, tus tswj kev nkag mus soj ntsuam cov cai sab hauv ntawm daim npav induction, muab piv nrog daim npav cov ntaub ntawv khaws cia hauv lub cuab yeej, thiab siv cov kev ua tom ntej.Tom qab tus neeg saib xyuas nkag tau ua tiav qhov kev txiav txim ntawm kev txais cov ntaub ntawv, nws yuav xa cov lus txib los teb rau daim npav nyeem ntawv, kom tus nyeem ntawv daim npav tuaj yeem rov qab mus rau lub xeev, thiab tib lub sijhawm, tus tswj kev nkag mus yuav rov qab mus rau kev saib xyuas hom.
