DRV8847 Dual H-Bridge Motor Driver
Isixhobo se-DRV8847 sisixhobo sokuqhuba injini ye-H-ibhulorho ezimbini kusetyenziso lwemizi-mveliso, izixhobo zasekhaya, iiprinta ze-ePOS, kunye nezinye izixhobo zokusebenza ze-mechatronic. Esi sixhobo sinokusetyenziselwa ukuqhuba iimotor ezimbini zeDC, i-bipolar stepper motor, okanye eminye imithwalo efana nokuhanjiswa. I-interface ye-PWM elula ivumela ujongano olulula kunye nomlawuli. Isixhobo se-DRV8847 sisebenza kunikezelo lwamandla olunye kwaye sixhasa uluhlu olubanzi lokubonelela ngegalelo ukusuka kwi-2.7 ukuya kwi-18 V.
Inqanaba lesiphumo somqhubi siquka i-N-channel yamandla e-MOSFETs aqwalaselwe njengeebhulorho ezimbini ezizeleyo ze-H zokuqhuba i-motor windings okanye iibhulorho ezine ezizimeleyo ezinesiqingatha (kwi-interface yebhulorho ezimeleyo). Ixesha elimiselweyo lilawula isantya esiphezulu kwibhuloho engakwazi ukuqhuba umthwalo we-1-A (i-2-A kwimodi ehambelanayo kunye nokushisa okufanelekileyo, kwi-25 ° C TA).
Imowudi yokulala yamandla aphantsi ibonelelwa ukuphumeza umzobo ophantsi othe cwaka ngokuvala uninzi lweesekethe zangaphakathi. Ukongeza, i-torque scalar ibonelelwa elinganisa ngokuguquguqukayo imveliso yangoku ngepini yedijithali. Olu phawu luvumela umlawuli ukuba anciphise langoku elifunekayo kusetyenziso lwamandla oluphantsi.
Imisebenzi yokukhusela yangaphakathi ibonelelwa nge-undervoltage-lockout, ukukhuselwa ngokugqithisileyo kwi-FET nganye, ukukhuselwa kweesekethe ezimfutshane, ukubonwa komthwalo ovulekileyo, kunye nokushisa. Iimeko zempazamo ziboniswa kwi-nFAULT pin. Ukwahluka kwesixhobo se-I 2C (DRV8847S) sineenkcukacha zokuxilonga.
