♠ DRV8876 H-Bridge Dirawalka Mootada oo leh Dareen Hadda iyo Nidaam isku dhafan
Qoyska DRV887x ee aaladaha ayaa ah wadayaasha mootada dabacsan ee codsiyada kala duwan.Aaladuhu waxay isku daraan N-channel H-bridge, bamka lacagtanidaamiyaha, dareenka hadda jira iyo habaynta, wax soo saarka saamiga hadda, iyo wareegga ilaalinta.Bamka dallacadu wuxuu wanaajiyaa waxtarka isagoo u oggolaanaya labadabaDhanka sare iyo kan-hoose ee N-channels MOSFETs iyo 100% taageerada wareegga shaqada.Qoyska qalabku waxay ku yimaadaan pin-to-pin, RDS(on) oo la qiyaasi karo doorashooyin si ay u taageeraan culaysyo kala duwan oo leh isbeddello naqshadeed oo yar.
Dareenka hadda la isku daray wuxuu u oggolaanayaa darawalku inuu nidaamiyo matoorka hadda socda inta lagu jiro bilawga iyo dhacdooyinka culeyska sarreeya.Xadka hadda jira waxa lagu dejin karaa tixraac danab dibadda ah oo la hagaajin karo.Intaa waxaa dheer, qalabyadu waxay bixiyaan wax soo saarka hadda oo u dhigma culeyska hadda jira.Tan waxa loo istcimaali karaa in lagu ogaado meesha matoorka taagan ama isbeddelka xaaladaha rarka.Dareenka isku dhafan ee hadda jira wuxuu isticmaalaa muraayad gudaha ah oo hadda jirta, taas oo meesha ka saaraysa baahida loo qabo caabiyaha shunt ee weyn, badbaadinta aagga guddiga iyo dhimista kharashka nidaamka.
Qaab hurdo yar oo awood yar ayaa la bixiyaa si loo gaaro sawir aadka u hooseeya iyadoo la xirayo inta badan wareegga gudaha.Astaamaha ilaalinta gudaha waxaa lagu bixiyaa quful ka hooseeya sahayda (UVLO), bamka ku dallaca ee danabka (CPUV), soosaarka xad dhaafka ah (OCP), iyo heerkulka qalabka (TSD).Xaaladaha cilladda waxaa lagu muujiyey nFAULT.
