♠ DRV8876 H-Bridge Umushoferi wa moteri hamwe nuburyo bwuzuye hamwe nubuyobozi
Umuryango wibikoresho bya DRV887x ni moteri yimodoka ihindagurika kubintu byinshi bitandukanye. Ibikoresho bihuza N-umuyoboro H-ikiraro, pompe yishyuzakugenzura, ibyiyumvo byubu no kugenzura, ibisohoka bigereranijwe, hamwe nuburinzi bwumuzunguruko. Amashanyarazi yishyurwa atezimbere imikorere yemerera byombiuruhande rwo hejuru kandi ruto-N-imiyoboro MOSFETs hamwe ninkunga yumusoro 100%. Umuryango wibikoresho biza muri pin-to-pin, igipimo kinini cya RDS (kuri) kugirango ushyigikire imitwaro itandukanye hamwe nimpinduka ntoya.
Kwishyira hamwe kwimyumvire yemerera umushoferi kugenzura moteri ya moteri mugihe cyo gutangira nibintu biremereye. Imipaka igezweho irashobora gushyirwaho hamwe noguhindura imbaraga zo hanze. Byongeye kandi, ibikoresho bitanga ibisohoka bigereranwa na moteri yumutwaro wa moteri. Ibi birashobora gukoreshwa mugushakisha aho moteri ihagarara cyangwa guhindura imiterere yimitwaro. Kwishyira hamwe kwimyumvire ikoresha indorerwamo yububiko bwimbere, ikuraho ibikenerwa nimbaraga nini ya shunt résistor, kuzigama ikibaho no kugabanya ibiciro bya sisitemu.
Uburyo buke bwo gusinzira butangwa kugirango ugere kuri ultralow quiescent ishushanya muguhagarika igice kinini cyimbere. Ibikoresho byo kurinda imbere bitangwa mugutanga amashanyarazi munsi (UVLO), pompe yishyurwa munsi ya voltage (CPUV), ibisohoka birenze urugero (OCP), hamwe nubushyuhe bukabije bwibikoresho (TSD). Ibihe bibi byerekanwe kuri nFAULT.
