DRV8847 Dual H-Bridge Motor Driver

ʻO ka mea DRV8847 he mea hoʻokele kaʻa kaʻa ʻelua H-bridge no nā noi ʻoihana, nā mea hana hale, nā mea paʻi ePOS, a me nā noi mechatronic ʻē aʻe.Hiki ke hoʻohana ʻia kēia hāmeʻa no ka hoʻokele ʻana i ʻelua mau kaʻa DC, kahi kaʻa stepper bipolar, a i ʻole nā ​​ukana ʻē aʻe e like me nā relay.Hāʻawi kahi pānaʻi PWM maʻalahi i ka maʻalahi me ka mea hoʻoponopono.Hoʻohana ʻia ka mea hana DRV8847 mai kahi lako mana hoʻokahi a kākoʻo i kahi kikowaena lako hoʻokomo ākea mai ka 2.7 a i ka 18 V.

ʻO ka pae hoʻopuka o ka mea hoʻokele he N-channel power MOSFET i hoʻonohonoho ʻia e like me ʻelua mau alahaka H piha e hoʻokele i nā wili kaʻa a i ʻole ʻehā mau alahaka kūʻokoʻa kūʻokoʻa (ma ke kikowaena alahaka kūʻokoʻa).ʻO ka manawa paʻa e hoʻomalu i ke au o ka piko o ke alahaka e hiki ai ke hoʻokele i ka haʻawe 1-A (2-A ma ke ʻano like me ka hoʻoemi wela kūpono, ma 25°C TA).

Hāʻawi ʻia kahi ʻano hiamoe haʻahaʻa haʻahaʻa no ka hoʻokō ʻana i kahi kaha kiʻi haʻahaʻa haʻahaʻa ma ke pani ʻana i ka nui o ka circuitry kūloko.Hoʻohui ʻia, hāʻawi ʻia kahi torque scalar e hoʻonui ikaika i ka hopena o kēia manawa ma o kahi pin komo kikohoʻe.Hāʻawi kēia hiʻohiʻona i ka mea hoʻoponopono e hoʻemi i kēia manawa no ka hoʻohana haʻahaʻa haʻahaʻa.

Hāʻawi ʻia nā hana pale kūloko no ka undervoltage-lockout, ka pale o ka overcurrent ma kēlā me kēia FET, ka pale kaapuni pōkole, ka ʻike haʻahaʻa, a me ka overtemperature.Hōʻike ʻia nā kūlana hewa ma ka pine nFAULT.He mau diagnostics kiko'ī ko ka I 2C device variant (DRV8847S).
