♠ DRV8876 H-Bridge Direban Mota Tare da Haɗin Haɓaka na Yanzu da Ka'ida
Iyalin na'urori na DRV887x direbobi ne masu sassauci don aikace-aikace iri-iri.Na'urorin sun haɗa N-channel H-bridge, famfon cajimai tsarawa, ji na yanzu da ƙa'ida, fitarwa na yau da kullun, da kewayen kariya.Famfu na caji yana inganta inganci ta hanyar ba da izini ga duka biyunMOSFETs masu girma-gefe da ƙananan-gefe N-tashoshi da tallafin sake zagayowar aiki 100%.Iyalin na'urori suna zuwa cikin fil-to-pin, zaɓuɓɓukan RDS (akan) masu daidaitawa don tallafawa lodi daban-daban tare da ƙananan canje-canjen ƙira.
Haɗe-haɗen ji na yanzu yana ba direba damar daidaita motsin motsi yayin farawa da manyan abubuwan da suka faru.Za'a iya saita iyaka na yanzu tare da madaidaicin ƙarfin lantarki na waje.Bugu da ƙari, na'urorin suna ba da fitarwa na halin yanzu daidai da abin da ake ɗauka na yanzu.Ana iya amfani da wannan don gano rumbun mota ko canza yanayin kaya.Haɗaɗɗen fahimtar halin yanzu yana amfani da gine-ginen madubi na ciki na yanzu, cire buƙatar babban ƙarfin shunt resistor, ceton yankin hukumar da rage farashin tsarin.
Ana samar da yanayin barci mai ƙarancin ƙarfi don cimma matsaya mai nisa a halin yanzu ta hanyar rufe yawancin kewayawa na ciki.An tanadar da fasalulluka na kariya na ciki don samar da kullewar ƙarancin wuta (UVLO), famfon caji ƙarƙashin ƙarfin lantarki (CPUV), fitarwa mai wuce gona da iri (OCP), da overtemperature na'urar (TSD).Ana nuna sharuɗɗan kuskure akan nFAULT.
