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).
• Keaukaha kaʻa kaʻa ʻelua H-alahaka
- Hoʻokahi a i ʻole ʻelua mau mīkini DC brushed
– Hookahi bipolar stepper motor
- Nā ukana Solenoid
• 2.7-V a hiki i ka 18-V ka laulā uila hana
• Kiʻekiʻe puka i kēia manawa no ka H-alahaka
– 1-A RMS mea hoʻokele i kēia manawa ma TA = 25°C
– 2-A RMS mea hoʻokele i kēia manawa ma ke ʻano like ʻole ma TA = 25°C
• Haʻahaʻa ma ka moku'āina kū'ē ma VM > 5-V
– 1000 mΩ RDS(ON) (HS + LS) ma TA = 25°C • Nā koho hoʻokele mana lehulehu
– 4-Pin interface
– 2-Pin interface
– Ke alahaka pili
– Kūʻokoʻa alahaka interface
• Hoʻoponopono i kēia manawa me 20-μs i hoʻopaʻa ʻia i ka manawa
• Torque scalar no ka hoʻonui ʻana i ka puka i kēia manawa i 50%
• Kākoʻo 1.8-V, 3.3-V, 5-V hoʻokomo logic
• Ke ano moe mana haahaa
– 1.7-µA Hāʻawi ʻia ke ʻano moe i kēia manawa ma VVM = 12-V, TA = 25°C
• Loaʻa i nā ʻano mea like ʻole I 2C (DRV8847S)
- Nā diagnostics kikoʻī ma nā papa inoa I 2C
– Kākoʻo hana kauā lehulehu
- Kākoʻo i ka maʻamau a me ka wikiwiki I 2C mode
• Nā pūʻolo liʻiliʻi a me nā kapuaʻi
- 16 Pin TSSOP (ʻaʻohe papa wela)
– 16 Pin HTSSOP PowerPAD™ pūʻolo
– 16 Pin WQFN puolo wela
• Nā hiʻohiʻona pale i kūkulu ʻia
- VM undervoltage lockout
- Ka palekana o ka overcurrent
– Wehe haawe ike
- Paʻa wela
– Pin hōʻike kūlana hewa (nFAULT)
• Pahu hau a me ka mea hana hau
• Nā mea holoi, nā mea maloʻo a me nā mea holoi ipu
• Nā mea paʻi kiʻi kiko-o-kuai (ePOS).
• Nā lako kukui kahua
• Nā mīkini kaapuni liʻiliʻi a me nā mika akamai
