ams AS5311 12-Bit Linear Incremental Position Sensor ene-ABI kanye ne-PWM Output User Manual
Incazelo evamile
I-AS5311 iyisishumeki somugqa sikazibuthe sokulungiswa okuphezulu okungenakuthinteki sokunyakaza okunembile komugqa kanye namanzwa ajikelezayo angaphandle kwe-axis anokulungiswa okufika ku-<0.5µm. Kuyi-system-on-chip, ehlanganisa izakhi zeHholo ezihlanganisiwe, isiphetho sangaphambili se-analog kanye nokucutshungulwa kwesignali yedijithali ku-chip eyodwa, epakishwe ngephakheji elincane le-TSSOP lamaphini angu-20.
Kudingeka umucu ozibuthe omningi noma indandatho enobude bepali obungu-1.0mm ukuze uzwe ukunyakaza okujikelezayo noma komugqa. Umucu kazibuthe ubekwe ngaphezu kwe-IC ebangeni lokuthayipha. 0.3mm.
Isilinganiso esiphelele sinikeza inkomba esheshayo yendawo kazibuthe ngaphakathi kwepheya yesigxobo esisodwa ngokulungiswa okungu-488nm ngesinyathelo ngasinye (i-12-bit ngaphezu kuka-2.0mm). Le datha yedijithali iyatholakala njenge-serial bit stream nanjengesignali ye-PWM.
Ngaphezu kwalokho, okukhiphayo okukhuphukayo kuyatholakala ngokulungiswa okungu-1.95 µm ngesinyathelo ngasinye. I-Index pulse ikhiqizwa kanye nge-pole pair (kanye ngo-2.0mm). Isivinini sokuhamba kumodi yokwenyuka singafika ku-650mm/ngesekhondi.
Ivolumu yangaphakathitagi-e regulator ivumela i-AS5311 ukuthi isebenze kokunikezwayo okungu-3.3 V noma okungu-5 V. Ngokuya ngohlelo lokusebenza i-AS5311 yamukela omazibuthe be-multi-pole strip kanye nozibuthe bendandatho enama-pole, womabili ama-radial kanye ne-axial magnetized.
Ukuze uthole imininingwane eyengeziwe yobuchwepheshe, sicela ubhekisele kumininingwane yedatha ye-AS5311, etholakalayo ukuze ilandwe kuma-ams webindawo.

I-AS5311 + Uzibuthe we-Multi-pole strip
Ibhodi ye-adaptha ye-AS5311
Incazelo yebhodi
Ibhodi ye-adaptha ye-AS5311 iyisekhethi elula evumela ukuhlola nokuhlola isishumeki somugqa se-AS5311 ngokushesha ngaphandle kokwakha into yokuhlola noma i-PCB.
I-PCB ingasetshenziswa njengeyunithi ezimele noma ixhunywe kusilawuli esincane. Ukusebenza okuzimele kudinga kuphela ukunikezwa kwamandla okungu-5V noma okungu-3V3, indawo kazibuthe epheya yesigxobo (ubude obu-2mm) ingafundwa ekuphumeni kwe-PWM, kanye nendawo ehlobene emiphumeleni ekhuphukayo ye-AB-Inkomba.

Ukukhweza ibhodi ye-adaptha ye-AS5311
I-AS5311 isebenzisa umucu ozibuthe we-multipole strip noma omazibuthe abayindandatho enobude bepali obungu-1.0mm. I-airgap phakathi kukazibuthe ne-AS5311 casing kufanele igcinwe kububanzi obungu-0.2mm~0.4mm. Isibambi sikazibuthe akumele sibe yi-ferromagnetic.
Izinto ezifana nethusi, ithusi, i-aluminium, insimbi engagqwali yizinqumo ezingcono kakhulu zokwenza le ngxenye.

Ukusebenza
Imodi yokukhipha ye-PWM ezimele
Isignali ye-PWM (iphinikhodi ye-JP2 #7) ivumela ukukala inani lendawo engu-12-bit eliphelele ngaphakathi kwepheya yesigxobo esisodwa (2.0mm). Inani lifakwe ikhodi kusiginali eshintshiwe yobubanzi be-pulse enobubanzi be-pulse engu-1µs ngesinyathelo ngasinye kanye ne-5V pulse voltagi-e ingaxhunywa ekufakweni kokuthwebula/kwesibali sikhathi se-microcontroller ukuze kuqondwe inani le-engeli.
Umphumela ophelele we-serial ubala kusukela ku-0….4095 phakathi kwepheya yesigxobo esisodwa ukuphinda ngepheya ngayinye elandelayo yezigxobo.
Okukhiphayo kwe-PWM kuqala ngobubanzi be-pulse obungu-1µs, kukhuphula ububanzi be-pulse ngesinyathelo ngasinye esingu-0.488µm futhi kufinyelele kububanzi be-pulse obukhulu obungu-4097µs ekupheleni kwepheya ngayinye yezigxobo. Bheka imininingwane yedatha ye-AS5311 ukuze uthole imininingwane eyengeziwe ngokuphuma kwe-PWM.
Imvamisa ye-PWM isikwa ngaphakathi ukuze ibe nokunemba okungu-5% (10% ngaphezu kwebanga eligcwele lokushisa

Ukusebenzisa i-serial interface ne-MCU
Isixazululo esiphelele nesinembile se-MCU sokufunda i-engeli kazibuthe yi-serial interface.
Inani lebhithi elingu-12 le-engeli lizofundwa ngokuqondile, futhi ezinye izinkomba njengolwazi lwamandla kazibuthe noma amabhithi e-alamu angafundwa ngesikhathi esifanayo.
Ukuxhumana phakathi kwe-MCU ne-adaptha board kungenziwa ngezintambo ezi-3.
3-wire serial interface
Isixhumi esibonakalayo se-Serial sivumela ukudluliswa kwedatha kolwazi lwendawo yomugqa we-12-bit (ngaphakathi kwepheya yesigxobo esisodwa = 2.0mm). Amabhithi edatha D11:D0 amele ulwazi lwendawo ngokulungiswa okungu-488nm (2000µm / 4096) ngesinyathelo ngasinye. I-CLK kumelwe ibe phezulu emaphethelweni awelayo e-CSn.
Uma i-CLK iphansi onqenqemeni oluwayo lwe-CSn, amabhithi okuqala ayi-12 amelela ulwazi lobukhulu, olulingana namandla kazibuthe.
