♠ DRV8876 H-Bridge Motor Driver Me ka Manaʻo o kēia manawa a me ka Hoʻoponopono

ʻO ka ʻohana DRV887x nā mea hoʻokele kaʻa maʻalahi no nā ʻano noi like ʻole.Hoʻohui nā mea hana i kahi alahaka N-channel H, hoʻopiʻi ukumea hoʻoponopono, ka ʻike a me ka hoʻoponopono ʻana, ka hoʻopuka proportional o kēia manawa, a me ka circuitry pale.Hoʻomaikaʻi ka pāpaʻi uku i ka pono ma ka ʻae ʻana i nā mea ʻeluaʻaoʻao kiʻekiʻe a me ka ʻaoʻao haʻahaʻa N-kanal MOSFET a me 100% kākoʻo pōʻai hana.Hele mai ka ʻohana o nā hāmeʻa i nā koho pin-to-pin, scalable RDS (on) e kākoʻo i nā ukana like ʻole me nā loli hoʻolālā liʻiliʻi.

Hiki i ka mea hoʻokele kaʻa ke hoʻoponopono i ke kaʻa o kēia manawa i ka wā hoʻomaka a me nā hanana haʻahaʻa kiʻekiʻe.Hiki ke hoʻonohonoho ʻia kahi palena o kēia manawa me kahi kuhikuhi volena waho hiki ke hoʻololi ʻia.Hoʻohui ʻia, hāʻawi nā hāmeʻa i kahi huahana e like me ke ʻano o ka ukana kaʻa.Hiki ke hoʻohana ʻia kēia no ka ʻike ʻana i ka stall kaʻa a hoʻololi paha i nā kūlana ukana.Ke hoʻohana nei ka ʻike hoʻohui i kēia manawa i kahi hoʻolālā aniani i loko o kēia manawa, e wehe ana i ka pono o ka mana shunt resistor nui, mālama i ka wahi papa a hoʻemi i ke kumukūʻai ʻōnaehana.

Hāʻawi ʻia kahi ʻano hiamoe haʻahaʻa haʻahaʻa no ka hoʻokō ʻana i ke kaha kiʻi ultralow quiescent current ma ka pani ʻana i ka hapa nui o ka circuitry kūloko.Hāʻawi ʻia nā hiʻohiʻona pale kūloko no ka hoʻolako ʻana i ka undervoltage lockout (UVLO), ka pahu hoʻoiho ma lalo o ka volta (CPUV), ka overcurrent (OCP), a me ka overtemperature device (TSD).Hōʻike ʻia nā kūlana hewa ma nFAULT.
