♠ 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. Inzwa yamanje ehlanganisiwe isebenzisa ukwakheka kwesibuko samanje sangaphakathi, 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-device overtemperature (TSD). Izimo zephutha zivezwe ku-nFAULT.
