I-MT9223 SOP8 umkhiqizo omusha Ukuthengiswa okushisayo

Uchungechunge lomkhiqizo we-MagnTek® MT9223 wumndeni wedivayisi yezinzwa yamanje ye-Hall Effect ehlanganiswe yodwa eklanyelwe inzwa yamanje ye-AC noma ye-DC ezinhlelweni zezimboni, ezentengiselwano, nezokuxhumana.Ngayinye ye-MT9223 iqukethe isekethe yeHholo enembile, ene-offset, ewumugqa ene-conductor yamanje enokumelana okuphansi etholakala eduze kwendawo yokufa.Umshini osetshenziswayo ogeleza kulo mzila wekhondatha wamanje ongazweli kancane udala inkambu kazibuthe iHholo IC eliyiguqulela libe amandla kagesi alinganayo.Okwamanje kuzwakala ngokuhlukile ukuze kwenqabe izinkambu zemodi evamile, kuthuthukiswe ukunemba ezindaweni ezinomsindo wamagnetic.Ukunemba kwedivayisi kuthuthukiswa ngokuba seduze kwendawo kazibuthe kuya ku-transducer yaseHholo.

Amandla kagesi anembile, alinganayo anikezwa i-low-offset, i-chopper-stabilized BCD Hall IC, elinganiselwe ngokunembile lapho ikhiqizwa.Okukhishwayo kwedivayisi kunomthambeka omuhle (>VOQ) lapho i-current ekhulayo igeleza kumzila we-conduction wamanje oyinhloko (kusuka kumaphini 1 no-2, ukuya kumaphini 3 kanye no-4).Ukumelana kwangaphakathi kwalo mzila we-conductive kuwu-1.2 mΩ okuvamile, okunikeza ukulahlekelwa kwamandla aphansi.Amatheminali endlela ye-conductive ahlukaniswe ngogesi kumzila wesiginali (amaphini 5 kuya ku-8).Lokhu kuvumela inzwa yamanje ye-MT9223 IC ukuthi isetshenziswe ezinhlelweni zamanje zomqondo ophakeme ngaphandle kokusebenzisa ezinye izindlela ezibizayo zokuzihlukanisa.

Umndeni wakwa-MT9223 uhlinzeka ngephakheji ye-SOP-8 kumakhasimende, Iphakheji iyahambisana ne-RoHS.
