DESCRIPTION
Ibhodi lokuhlola le-CTD221-BB-1.5 lidizayinelwe ukukhombisa amandla amanje okuzwa we-CT220 linear magnetic sensor evela ku-Allegro MicroSystems. I-CT220 iyinzwa yamanje engathinteki esekelwe kubuchwepheshe be-XtremeSense™ tunnel magnetoresistance (TMR). Ifaka ukucushwa kwebhuloho eligcwele okuhlanganisa izinto ezine ze-TMR ezihlanganiswe monolithically nokujikeleza okusebenzayo kwe-CMOS, okuyivumela ukuthi ibe nokulungiswa okuphezulu nomsindo ophansi endaweni yephakheji encane. Lo mhlahlandlela womsebenzisi uchaza indlela yokuxhuma nokusebenzisa ibhodi lokuhlola le-CTD221-BB-1.5.
IZICI
- Ibanga lenkundla: ±1.5 mT

UKUSEBENZISA IBHODLU LOKUHLOLA
Lesi sigaba sinikeza i-overview kokuxhumana nezinketho zokumisa zebhodi lokuhlola le-CTD221-BB-1.5. Iqembu ngalinye lokuxhumana eligqanyiswe kuMfanekiso 2 linesigaba semininingwane ngezansi. Imininingwane yomkhiqizo iqukethe ulwazi oluningiliziwe mayelana nokusetshenziswa nokusebenza kwephinikhodi ngayinye futhi kufanele ithintwe ukuze uthole ulwazi oluningiliziwe kunalolo oluqukethwe kulo mhlahlandlela womsebenzisi.
Ibhodi lokuhlola linikwa amandla ngokuxhuma i-DV bias voltage phakathi kwe-VCC kanye nezikhonkwane ze-GND ku-PCB. Iphinikhodi ye-OUT ye-PCB kufanele ixhunywe ku-voltmeter yedijithali (DVM) noma i-oscilloscope ukuze kuqashwe okukhiphayo kwenzwa yamanje ye-CT220. Idatha ekhona kulesi sigaba ingeyevolumu ye-5 Vtage.
Imodi Yamanje Ephansi
Kumodi yamanje ephansi, okwamanje kudlula ukulandelela okungu-0.9 mm-wide kusendlalelo esiphezulu se-PCB. Le modi ingasetshenziswa ukukala ama-currents ebangeni elingu-±3.85 A. Ukusulwa phakathi kwe-trace ne-IC pads ngu-0.35 mm, okunikeza ukuhlukaniswa okungu-1 kV phakathi kwe-trace yamanje namaphinikhodi we-SOT23. Ngokungeziwe kulayini omuhle kakhulu kuwo wonke amazinga okushisa, isilinganiso esiphezulu sesignali-kuya-noise (SNR) se-CT220 siyenza ikwazi ukukala amaza aphansi kakhulu. I-CTD221 ikwazi ukubona imisinga ephansi njenge-5 mA.
Imodi Yamanje Emaphakathi
Kumodi yamanje emaphakathi, okwamanje kudlula ukulandelela okungu-2 mm-wide kungqimba engezansi ye-PCB. Lokhu kulandelelwa okubanzi (uma kuqhathaniswa nemodi yamanje ephansi) kuvumela ukuthi kutholwe umsinga omkhulu. Le modi ingasetshenziswa ukukala ama-currents angu-±10 A, enekhono lokuxazulula ngezinyathelo ezingu-10 mA. Ukuhlukaniswa kwe-CT220 kwalokhu kucushwa kungu-5.1 kVrms ngenxa yokuthi ibanga phakathi kwe-trace engezansi namaphinikhodi we-SOT23 ngu-1.6 mm.
Imodi Yamanje Ephezulu
Imodi yamanje ephezulu isetshenziselwa izinhlelo zokusebenza ezibandakanya imisinga emikhulu kakhulu ukuthi ingadlula ekulandeleleni kwe-PCB. Kule modi, i-current idluliswa ngebhasi yethusi. Ibha yebhasi ingu-1/2” ububanzi no-1/16” obukhulu. Umsebenzisi unokuvumelana nezimo ukulungisa ibanga lebhasi ukusuka phezulu kwe-PCB esebenzisa ipulasitiki, amawasha amelana nokushisa. Ibhodi lokuhlola le-CTD221 lithunyelwa nama-spacers ukuze kugcinwe igebe elingu-4 mm phakathi kwe-PCB nebha yebhasi. Ngalokhu kumisa, i-CTD221 ingasetshenziswa ukukala ama-currents ebangeni eliphelele le-50 A kanye nokulinganisa ama-currents ebangeni elingu-±50 A nge-50 mA resolution. Ngebanga lesikhala lika-4 mm phakathi kwe-CT220 ne-busbar, i-isolation voltage idlula 5.1 kVrms kumodi yamanje ephezulu.
