♠ Umshayeli wevalvu wezimoto ezineziteshi ezi-4
I-L9305 iyi-IC elungisekayo, i-monolithic solenoid driver edizayinelwe ukulawula ama-solenoid aqondile ukuze azidlulisele ngokuzenzakalelayo, isilawuli sokuqina ngogesi, nezinhlelo zokusebenza ezisebenzayo zokumiswa.Amashaneli amane angacushwa njengamashayeli asemaceleni aphansi noma aphezulu kunoma iyiphi inhlanganisela.Idivayisi ihlanganisa i-transistor yamandla, i-recirculation transistor kanye nenzwa yamanje yakho kokubili amandla kanye ne-recirculation transistor.Lesi sakhiwo siqinisekisa ukungabi namsebenzi kwesilinganiso samanje sesiteshi ngasinye.
I-current elawulwayo iyahleleka kububanzi obungu-0-1.5 A (ububanzi obuvamile), ngokulungiswa kuka-0.25 mA, noma u-0-2 A (ububanzi obunwetshiwe), ngokulungiswa kuka-0.33 mA.Umsebenzisi angakwazi ukweqa ukuguquguquka kwe-dither okulungisekayo ngaphezu kwephoyinti elimisiwe lamanje.
Isixhumi esibonakalayo se-SPI esingu-32-bit CRC esivikelwe sisetshenziselwa ukulungisa nokulawula wonke amashaneli futhi sinikeza impendulo yesimo yayo yonke imisebenzi yokuxilonga.Okokufaka okusebenzayo okuphansi kokusetha kabusha, i-RESN, kusetshenziselwa ukuvala wonke amashaneli futhi kusethwe kabusha amarejista angaphakathi abe amanani awo azenzakalelayo.Indlela yokuvumela ephephile inikezwa ngephinikhodi ethi EN_DR kanye ne-Fail Safe Pre-driver edidiyelwe.Umzila wokucisha ukuphepha okungadingekile uqinisekisa ukuthi amaphutha abalulekile angaphakathi akhubaza isishayeli sangaphambili esiphephile.Iphinikhodi ephezulu esebenzayo, EN_DR, isetshenziselwa ukunika amandla noma ukukhubaza ukusebenza kwazo zonke iziteshi.Uma iphinikhodi ye-EN_DR iphansi, zonke iziteshi ziyacishwa.Iphinikhodi yokukhipha iphutha inikeziwe futhi ingasetshenziswa ukukhiqiza ukuphazamiseka kwangaphandle kusilawuli esincane noma nini lapho iphutha litholwa.Umsebenzisi angakwazi ukukhomba amaphutha athile kuphinikhodi ye-FAULTn ngokusekelwe ezidingweni zabo ezithile zesistimu.
• I-AEC-Q100 ifanelekile
• Izishayeli ezilawulwayo zamanje ze-LSD/HSD ezineziteshi ezi-4
- Indlela yomqondo yamanje ehlanganisiwe '
– Ukunemba kwamanje (ebangeni elivamile) ◦ ± 5 mA ku-0 kuya ku-0.5 Ububanzi ◦ ± 1% ku-0.5 A kuya ku-1.5 A ububanzi
– Ukunemba kwamanje (ebangeni elinwetshiwe) ◦ ± 15 mA ku-0 kuya ku-0.3 Ububanzi ◦ ± 5% ku-0.3 A kuya ku-0.5 A ububanzi ◦ ± 4% ku-0.5 A kuya ku-2 A uhla
– Umshayeli omkhulu RDSON 375 mΩ @ 175 °C
– 13-bit yamanje set-point ukulungiswa
- Isilawuli samanje esishintshashintshayo nesigxilile
- Umsebenzi we-dither ohlelekayo
- Ukulawula izinga lomshayeli okhethiwe
• Izici zokuphepha
- Uhlangothi oluphezulu lwehluleka ngokuphephile VUMELA ukushintsha umshayeli wangaphambili ngokuqapha kwe-VDS
- Indlela engasebenzi yokuphepha engasebenzi
- Ukuxilongwa okuthuthukisiwe nokuqapha usebenzisa i-BIST
- Inzwa yokushisa nokuqapha
- Inzwa yamanje engafuneki kuzo zonke iziteshi
- Imemori yokulinganisa nokumisa kufaka phakathi i-CRC
- Vikela ukuxhumana kwe-serial usebenzisa impendulo yekheli, i-5-bit CRC, isibali sozimele kanye nokutholwa kohlaka olude/ olufushane
– Bhalisa ukuqinisekiswa
• Ukuxhumana kwe-32-bit SPI nokuqinisekiswa komlayezo we-5-bit CRC
• Izinketho zephakheji: PWSSO36, TQFP48
• Ukuthobela okuphelele kwe-ISO26262, amasistimu we-ASIL-D aselungile
