♠ I-Octal high-side smart power solid-state relay ene-serial/parallel interface ekhethekayo ku-chip
I-VNI8200XP iyi-monolithic 8-channel driver ene-supply yamanje ephansi kakhulu, ene-interface ye-SPI edidiyelwe nokusebenza kahle okuphezulu kwe-100 mA micropower step-down switching regulator peak current control loop mode.I-IC, etholakala kubuchwepheshe be-STMicroelectronics™ VIPower™, ihloselwe ukushayela noma yiluphi uhlobo lomthwalo ngohlangothi olulodwa oluxhunywe phansi.
Umkhawulo wamanje wesiteshi osebenzayo uhlanganiswe nokuvalwa kokushisa, okuzimele esiteshini ngasinye, nokuqalisa kabusha okuzenzakalelayo, vikela idivayisi ekulayishweni ngokweqile.
Imisebenzi eyengeziwe eshumekiwe yilena: ukulahleka kokuvikela kwe-GND okuvala ngokuzenzakalelayo okukhishwayo kwedivayisi uma kwenzeka inqanyulwa phansi, ukuvalwa kwe-undervoltage nge-hysteresis, ukuxilongwa kwe-Power Good yokuqashelwa kwebanga le-voltage esebenzayo, okukhiphayo kunika amandla ukusebenza kokuphuma kwamandla okusheshayo KUVULIWE/KUVALIWE, futhi kuyahleleka. umsebenzi we-watchdog wokusebenza okuphephile kwe-microcontroller;ukuvikela izinga lokushisa elingaphezulu kwecala ukuze ulawule izinga lokushisa lekesi le-IC.
Idivayisi ishumeka iperipheral ye-SPI enezintambo ezine enemisebenzi ekhethekayo engu-8 noma engu-16-bit;ngokusebenzisa iphinikhodi idivayisi ingaphinda isebenze ngesixhumi esibonakalayo esihambisanayo.
Kokubili ukusebenza kwe-8-bit kanye ne-16-bit SPI kuyahambisana noxhumano lwe-daisy chain.
Isixhumi esibonakalayo se-SPI sivumela umyalo womshayeli okhiphayo ngokunika amandla noma ukukhubaza isiteshi ngasinye esinefomethi engu-16-bit, isilawuli sokuhlola ukulinganiswa kokuqina kokuxhumana.Iphinde ivumele ukugadwa kwesimo se-IC esisayinda Amandla Okuhle, isimo sokushisa ngokweqile esiteshini ngasinye, ukutholwa kwezinga lokushisa okusexwayiso kwangaphambili kwe-IC.
Ukuvalwa kwe-thermal okwakhelwe ngaphakathi kuvikela i-chip ekushiseni ngokweqile kanye ne-short-circuit.Esimeni sokugcwala ngokweqile, isiteshi IYAVALA futhi UVULA futhi ngokuzenzakalelayo ngemva kokuba izinga lokushisa le-IC lehlile ngaphansi komkhawulo obekwe yi-hysteresis yezinga lokushisa ukuze izinga lokushisa lenhlanganiso lilawuleke.Uma lesi simo senza izinga lokushisa lecala lifinyelele umkhawulo wezinga lokushisa, i-TCSD, amashaneli alayishwe ngokweqile ayavalwa futhi aqalise kabusha, hhayi ngesikhathi esisodwa, lapho izinga lokushisa lekesi kanye nokuhlangana lehla ngaphansi komkhawulo wawo wokusetha kabusha.Uma isimo sokusetha kabusha okushisayo, amashaneli alayishiwe awavulwa kuze kufike umcimbi wokusetha kabusha izinga lokushisa.Iziteshi ezingalayishiwe ziyaqhubeka nokusebenza ngendlela evamile.Izinga lokushisa lekesi elingaphezu kwe-TCSD libikwa ngephinikhodi ye-WARN evulekile yokukhipha amanzi.Isekhethi yangaphakathi ihlinzeka ngokubika kwenkomba ye-FAULT okungaxhunywanga okungaxhunywanga uma kwenzeka esinye salezi zenzakalo ezilandelayo: i-OVT yesiteshi (izinga lokushisa elingaphezulu), ukuhlolwa kokulinganisa kwehluleka.I-Power Good diagnostic ixwayisa isilawuli ukuthi i-voltage yokunikezela ingaphansi komkhawulo ogxilile.Umsebenzi we-watchdog usetshenziselwa ukuthola ukwenzeka kwephutha lesofthiwe yesilawuli sokusingatha.I-watchdog circuitry idala ukusetha kabusha kwangaphakathi lapho kuphelelwa isikhathi se-watchdog yangaphakathi.Ukusetha kabusha isibali sikhathi se-watchdog kungafinyelelwa ngokusebenzisa i-pulse negative kuphinikhodi ye-WD.Umsebenzi we-watchdog ungacishwa iphinikhodi ezinikele ye-WD_EN.Le phinikhodi iphinde ivumele ukuhlelwa kohlu olubanzi lwezikhathi ze-watchdog.
Isifunda somshayeli we-matrix we-LED yangaphakathi (imigqa emi-4, amakholomu angu-2) ivumela ukutholwa kwesimo sokuphumayo okukodwa.Isilawuli sikagesi esihlanganisiwe sokuya phansi sinikeza amandla kagesi kumshayeli we-matrix we-LED yangaphakathi kanye namabhafa okukhiphayo okunengqondo futhi angasetshenziswa ukuhlinzeka ngama-optocoupler angaphandle uma uhlelo lokusebenza ludinga ukuhlukaniswa.Isilawuli sivikelekile ezimeni zesiyingi esifushane noma zokulayisha ngokweqile ngenxa yomkhawulo wamanje we-pulse-by-pulse ene-loop yokulawula yamanje ephezulu.
