DRV8847 Dual H-Bridge Motor Driver
Idivayisi ye-DRV8847 ingumshayeli wemoto we-H-bridge wezinhlelo zokusebenza zezimboni, izinto zikagesi zasendlini, amaphrinta e-ePOS, nezinye izinhlelo zokusebenza ze-mechatronic. Le divayisi ingasetshenziselwa ukushayela amamotho e-DC amabili, i-bipolar stepper motor, noma eminye imithwalo efana nokudluliselwa. Isixhumi esibonakalayo esilula se-PWM sivumela isikhombimsebenzisi esilula nesilawuli. Idivayisi ye-DRV8847 isebenza ngaphandle kokuphakelwa kwamandla okukodwa futhi isekela uhla lokuhlinzekwa kokufakwayo olubanzi ukusuka ku-2.7 kuya ku-18 V.
Isigaba sokuphuma somshayeli siqukethe ama-MOSFET wamandla we-N-channel amiswe njengamabhuloho amabili agcwele e-H ukuze ashayele ama-motor windings noma amabhuloho amane azimele angamahhafu (esixhumi esibonakalayo sebhuloho elizimele). Isikhathi esinqunyiwe silawula amandla aphezulu ebhulohweni elingashayela umthwalo ongu-1-A (2-A kumodi ehambisanayo ngokucwiliswa kokushisa okufanele, ku-25°C TA).
Imodi yokulala yamandla aphansi inikezwa ukuze kuzuzwe ukudonsa okuphansi kwamanje okuthule ngokuvala ingxenye enkulu yokujikeleza kwangaphakathi. Ukwengeza, kunikezwa isikali se-torque esikala ngokuguqukayo umthamo wamanje ngephinikhodi yokufaka yedijithali. Lesi sici sivumela isilawuli sehlise okwamanje okudingekayo ukuze kusetshenziswe amandla aphansi.
Imisebenzi yokuvikela yangaphakathi ihlinzekelwe ngokukhiya i-undervoltage, ukuvikela okudlulele ku-FET ngayinye, ukuvikelwa kwesekethe emfushane, ukutholwa komthwalo ovulekile, kanye nezinga lokushisa elingaphezu kwamandla. Izimo zephutha zikhonjiswa ngephinikhodi ye-nFAULT. Okuhlukile kwedivayisi ye-I 2C (DRV8847S) kunokuxilonga okuningiliziwe.
