♠ DRV8876 H-Bridge Motor Driver Ngengqondo eDityanisiweyo yangoku kunye noMgaqo
Usapho lwe-DRV887x lwezixhobo ngabaqhubi beemoto ezibhetyebhetye kwiintlobo ngeentlobo zezicelo. Izixhobo zidibanisa i-N-channel H-bridge, impompo yentlawuloumlawuli, imvakalelo yangoku kunye nommiselo, imveliso elinganayo yangoku, kunye nokhuseleko lwesekethe. Ipompo yentlawulo iphucula ukusebenza kakuhle ngokuvumela zombinikwicala eliphezulu kunye necala elisezantsi i-N-channels ye-MOSFETs kunye ne-100% yenkxaso yomjikelo womsebenzi. Usapho lwezixhobo luza nge-pin-to-pin, iinketho ze-RDS ezikhawulezayo (kwi) ukuxhasa imithwalo eyahlukeneyo kunye notshintsho oluncinci loyilo.
Imvakalelo yangoku edibeneyo ivumela umqhubi ukuba alawule i-motor current ngexesha lokuqalisa kunye neziganeko zomthwalo ophezulu. Umda wangoku unokusetwa ngereferensi yombane yangaphandle ehlengahlengisiweyo. Ukongeza, izixhobo zibonelela ngemveliso yangoku ngokuhambelana nomthwalo wemoto yangoku. Oku kungasetyenziselwa ukubona indawo yokumisa imoto okanye utshintsho kwiimeko zomthwalo. Ingqiqo yangoku edibeneyo isebenzisa i-architecture yangaphakathi yesibuko yangoku, isusa imfuno ye-shunt resistor enkulu yamandla, indawo yokugcina ibhodi kunye nokunciphisa iindleko zenkqubo.
Imowudi yokulala yamandla aphantsi ibonelelwe ukuphumeza umzobo wangoku othe cwaka ngokuvala uninzi lweesekethe zangaphakathi. Iimpawu zokukhusela zangaphakathi zibonelelwa ukubonelela nge-undervoltage lockout (UVLO), ipompo yokutshaja phantsi kwe-voltage (CPUV), i-overcurrent ye-output (OCP), kunye nobushushu obungaphezulu kwesixhobo (TSD). Iimeko zeempazamo zibonakaliswe kwi-nFAULT.
