♠ I-Automotive 4-channel valve driver
I-L9305 yi-IC eqwalaselweyo, i-monolithic solenoid umqhubi we-IC eyenzelwe ukulawula i-solenoids yomgca yokudluliselwa okuzenzekelayo, ulawulo lozinzo lwe-elektroniki, kunye nezicelo zokunqunyanyiswa okusebenzayo.Imijelo emine inokuqwalaselwa njengecala eliphantsi okanye abaqhubi becala eliphezulu kuyo nayiphi na indibaniselwano.Isixhobo sibandakanya i-transistor yamandla, i-recirculation transistor kunye nemvakalelo yangoku zombini amandla kunye ne-recirculation transistor.Olu lwakhiwo luqinisekisa ukungafuneki komlinganiselo wangoku kwitshaneli nganye.
Umbane olawulwayo ulungelelaniswe kwi-0-1.5 A (uluhlu oluqhelekileyo), kunye nesisombululo se-0.25 mA, okanye i-0-2 A (uluhlu olwandisiweyo), kunye nesisombululo se-0.33 mA.Umsebenzisi unokumisela uhlengahlengiso olunoqwalaselo lwe-dither ngaphezulu kwendawo esetiweyo yangoku.
I-32-bit CRC ekhuselweyo ujongano lwe-SPI isetyenziselwa uqwalaselo nolawulo lwazo zonke iitshaneli kwaye ibonelela ngengxelo yobume bayo yonke imisebenzi yokuxilonga.Igalelo lokusetha kwakhona eliphantsi elisebenzayo, i-RESN, isetyenziselwa ukukhubaza onke amajelo kunye nokusetha kwakhona iirejista zangaphakathi kumaxabiso azo angagqibekanga.Indlela ekhuselekileyo yokwenza inikwe nge-EN_DR pin kunye ne-Fail Safe Pre-driver ehlanganisiweyo.Indlela yokucinywa yokhuseleko engafunekiyo iqinisekisa ukuba iziphene ezibalulekileyo zangaphakathi zikhubaza umqhubi wangaphambili okhuselekileyo.Iphinikhodi ephezulu esebenzayo, EN_DR, isetyenziselwa ukwenza okanye ukuvala ukusebenza kwawo onke amajelo.Xa iphini ye-EN_DR iphantsi, onke amajelo avaliwe.I-pin ye-fault output inikezelwa kwaye ingasetyenziselwa ukuvelisa ukuphazamiseka kwangaphandle kwi-microcontroller nanini na xa kufunyenwe impazamo.Umsebenzisi angenza imephu yeempazamo ezithile kwi-FAULTn pin ngokusekwe kwiimfuno zabo zenkqubo ethile.
• I-AEC-Q100 ifanelekile
• I-4-channel ezimeleyo ye-LSD/HSD abaqhubi abalawulwayo ngoku
-Indlela yengqiqo yangoku edibeneyo '
– Ukuchaneka kwangoku (kuluhlu oluqhelekileyo) ◦ ± 5 mA kwi-0 ukuya ku-0.5 Uluhlu ◦ ± 1% kwi-0.5 A ukuya ku-1.5 A uluhlu
– Ukuchaneka kwangoku (kuluhlu olwandisiweyo) ◦ ± 15 mA ku-0 ukuya ku-0.3 Uluhlu ◦ ± 5% ku-0.3 A ukuya ku-0.5 Uluhlu ◦ ± 4% kwi-0.5 A ukuya ku-2 A uluhlu
