VNH5019ATR-E Motoci/Motion/Masu sarrafa wuta & Direbobi Mota H-Bridge 18mOhm 30A 41V VCC

VHN5019A-E cikakken direban motar gada ne wanda aka yi niyya don aikace-aikacen mota da yawa. Na'urar ta ƙunshi manyan direbobi masu gefe guda biyu da ƙananan maɓallan gefe guda biyu. An ƙirƙira madaidaicin direba na gefe ta amfani da STMicroelectronics sanannu kuma tabbataccen fasaha na VIPower® M0 wanda ke ba da damar haɗawa da inganci akan mutun Motsi na gaskiya na MOSFET tare da sigina / da'irar kariya.

An haɗa dice guda uku a cikin kunshin MultiPowerSO-30 akan firam ɗin gubar da aka ware. Wannan fakitin, wanda aka ƙera musamman don ƙaƙƙarfan mahallin mota yana ba da ingantacciyar aikin zafi godiya ga faɗuwar faɗuwar rana. Sigina na shigarwa INA da INB na iya yin mu'amala da microcontroller kai tsaye don zaɓar jagoran motar da yanayin birki.

DIAGA/ENA ko DIAGB/ENB, idan an haɗa su da resistor na waje, yana ba da ƙafa ɗaya na gada. Hakanan yana ba da siginar ganowa na dijital martani. Fitin CS yana ba da damar saka idanu akan halin yanzu na motar ta hanyar isar da daidaitattun halin yanzu zuwa ƙimar sa lokacin da CS_DIS fil aka kora ƙasa ko hagu a buɗe. PWM, har zuwa 20 kHz, yana ba mu damar sarrafa saurin motar a duk yanayi mai yiwuwa. A kowane hali, ƙaramin matakin ƙasa akan fil ɗin PWM yana kashe duka LSA da LSB masu sauyawa. Lokacin da PWM ya haura zuwa babban matakin, LSA ko LSB suna sake kunnawa dangane da yanayin shigar fil. Ƙayyadaddun fitarwa na yanzu da kuma rufewar zafi suna kare abin da ya shafi babban gefen a takaice zuwa yanayin ƙasa.

Ana bayyana gajeriyar yanayin baturi ta hanyar gano abin da ake ɗauka ko kuma ta hanyar rufewar zafi wanda ke kashe ƙaramin gefen da ya dace.

Matsar wutar lantarki mai aiki da VCC tana kare na'urar daga ƙarancin kuzari a cikin duk saiti na motar. Fitin CP yana ba da madaidaicin ƙofa don tashar N-tashar PowerMOS ta waje da ake amfani da ita don juyar da kariyar polarity.
