♠ DRV8876 H-Bridge Motor Driver With Integrated Current Sense and Regulation
Umndeni wamadivayisi we-DRV887x ungabashayeli bezimoto abaguquguqukayo ezinhlobonhlobo zezinhlelo zokusebenza.Amadivayisi ahlanganisa i-N-channel H-bridge, iphampu yokushajaisilawuli, izinzwa zamanje kanye nokulawula, okukhiphayo kwamanje ngokulinganayo, kanye nesekhethi yokuvikela.Iphampu yokushaja ithuthukisa ukusebenza kahle ngokuvumela kokubiliama-MOSFET eziteshi ezisezingeni eliphezulu neziphansi kanye nokwesekwa okungu-100% komjikelezo womsebenzi.Umndeni wamadivayisi ufika ngephini-to-pin, izinketho ze-RDS(zivuliwe) ezingakala ukuze zisekele imithwalo ehlukene ngezinguquko ezincane zedizayini.
Izinzwa zamanje ezihlanganisiwe zivumela umshayeli ukuthi alawule amandla emotor ngesikhathi sokuqalisa kanye nemicimbi yokulayisha okuphezulu.Umkhawulo wamanje ungasethwa ngereferensi ye-voltage yangaphandle elungisekayo.Ukwengeza, amadivaysi ahlinzeka ngokukhiphayo kwamanje ngokulingana nomthwalo wemoto wamanje.Lokhu kungasetshenziswa ukuthola indawo yokudayisa izimoto noma ukushintsha izimo zomthwalo.Izinzwa zamanje ezihlanganisiwe zisebenzisa i-architecture yangaphakathi yesibuko samanje, isusa isidingo se-resistor enkulu ye-shunt yamandla, indawo yokulondoloza ibhodi kanye nokunciphisa izindleko zesistimu.
Imodi yokulala yamandla aphansi inikezwa ukuze kutholwe ukudonswa kwamanje okuthule kakhulu ngokuvala iningi lokujikeleza kwangaphakathi.Izici zokuvikela zangaphakathi zihlinzekelwe ukukhiywa kwe-supply undervoltage (UVLO), iphampu yokushaja ngaphansi kwe-voltage (CPUV), i-output overcurrent (OCP), kanye ne-overtemperature yedivayisi (TSD).Izimo zephutha zivezwe ku-nFAULT.
