Inkcazelo ye-DRV8871
Isixhobo se-DRV8871 sisixhobo se-brush-DC somqhubi wemoto kubashicileli, izixhobo zombane, izixhobo zemizi-mveliso, kunye nabanye oomatshini abancinci.Amagalelo amabini alawula ibhulorho ye-H, equka i-N-channel MOSFETs ezine ezikwazi ukulawula iimotor macala omabini ukuya kuthi ga kwi-3.6-A incopho yangoku.Amagalelo anokuba yi-bepulse-width modulated (PWM) ukulawula isantya semoto, usebenzisa ukhetho lweendlela zokubola kwangoku.Ukusetha omabini amagalelo aphantsi kungena kwindlela yokulala yamandla aphantsi.
Isixhobo se-DRV8871 sinesekhethi ephucukileyo yolawulo lwangoku engasebenzisi ireferensi yombane we-analog okanye isixhasi sangaphandle.Esi sisombululo senoveli sisebenzisa i-standard yexabiso eliphantsi, i-low-power resistor ukuseta i-currentthreshold.Ukukwazi ukukhawulela okwangoku kwinqanaba elaziwayo kunokunciphisa kakhulu iimfuno zamandla enkqubo kunye nesambuku somthamo ofunekayo ukugcina amandla ombane azinzileyo, ngakumbi imeko ye-motor startupa kunye neemeko zokumisa.
Isixhobo sikhuselwe ngokupheleleyo kwiimpazamo kunye neesekethe ezimfutshane, kubandakanywa i-undervoltage (UVLO), i-overcurrent (OCP), kunye ne-overtemperature (TSD).Xa imeko yempazamo isusiwe, isixhobo siphinda siqalise ukusebenza okuqhelekileyo ngokuzenzekelayo.
