I-STSPIN32F0TR IND & POWER CONV

Incazelo

I-STSPIN32F0 iyi-System-In-Package ehlinzeka ngesixazululo esihlanganisiwe esifanele ukushayela amamotho e-BLDC ezigaba ezintathu kusetshenziswa izindlela zokushayela ezihlukene.Ishumeka umshayeli wesango lesigamu sebhuloho eliphindwe kathathu elikwazi ukushayela ama-MOSFET noma ama-IGBT amandla akhona njengamanje angama-600 mA (usinki nomthombo).Amaswishi ezinhlangothi eziphakeme neziphansi zebhuloho elifanayo alikwazi ukushayelwa phezulu ngesikhathi esisodwa ngenxa yomsebenzi ohlanganisiwe wokukhiya.Isiguquli sebhaka sangaphakathi se-DC/DC sinikeza amandla kagesi angu-3.3 V afaneleka ukunikeza kokubili i-MCU nezingxenye zangaphandle.Isilawuli somugqa sangaphakathi se-LDO sinikeza amandla kagesi wokuphakela abashayeli bamasango.Ama-amplifiers ahlanganisiwe okusebenza ayatholakala ukuze kubekwe isignali yezinzwa ze-analog Hall-effect kanye nesignali ye-shunt resistor.Isiqhathanisi esinomkhawulo ohlelekayo sihlanganiswe ukwenza ukuvikela okudlulele.I-MCU ehlanganisiwe (STM32F031C6 enebanga lokushisa elinwetshiwe, inguqulo engu-7 yesijobelelo) ivumela ukwenza ukulawula okugxile emkhakheni, inzwa yezinyathelo ezingu-6 kanye nezinye i-algorithm yokushayela ethuthukisiwe kuhlanganise ne-loop yokulawula isivinini.Inesici sokuvikela ukubhala kanye nesivikelo sokufunda sememori ye-Flash eshumekiwe ukuze ivikele ekubhaleni okungafunwa kanye/noma ukufunda.Idivayisi ye-STSPIN32F0 iphinda ifake izivikelo zokukhiya ngaphandle kwe-overvoltage futhi ingafakwa kumodi yokulinda ukuze kuncishiswe ukusetshenziswa kwamandla.Lolu cingo luhlinzeka ngezimbobo ze-I/O zenjongo evamile eziyi-16 (GPIO) ezinekhono lokubekezelela i-5 V, isiguquli esisodwa se-analog-to-digital esingu-12-bit esineziteshi ezifika kweziyisi-9 ezenza ukuguqulwa ngemodi yokushutha okukodwa noma yokuskena, inhloso ejwayelekile engu-5 evumelanisekayo. izibali sikhathi futhi isekela ukusebenziseka kalula kokulungisa iphutha kwe-serial interface (SWD).
