Maopopo iā ʻoe he aha ke IC LED?

ʻO ka Light Emitting Diode Integrated Circuit i kapa ʻia ʻo LED IC. He ʻano kaapuni i hoʻohui ʻia i hana ʻia no ka hoʻokele a hoʻokele i nā LED, a i ʻole nā ​​diodes māmā. Hāʻawi nā LED integrated circuits (ICs) i nā ʻano hana like ʻole, me ka hoʻoponopono ʻana i ka voltage, dimming, a me ka mana o kēia manawa, e hoʻomaʻamaʻa i ka hoʻokele pololei a me ka maikaʻi o nā ʻōnaehana kukui LED. ʻO nā noi no kēia mau kaapuni i hoʻohui ʻia (ICs) e loaʻa nā paneli hōʻikeʻike, nā kukui kukui, a me ka hoʻomālamalama kaʻa.
ʻO ka acronym no ka Integrated Circuit ʻo IC. He mea uila liʻiliʻi ia i hana ʻia me nā ʻāpana semiconductor-fabricated, me nā mea pale, transistors, capacitors, a me nā ʻāpana uila ʻē aʻe. ʻO nā hana uila e like me ka amplification, ka hoʻololi ʻana, ka hoʻoponopono uila, ka hana hōʻailona, ​​a me ka mālama ʻana i ka ʻikepili nā hana nui o kahi kaapuni i hoʻohui ʻia (IC). nā kaapuni hoʻohui (ICs). Ma ka hoʻohui ʻana i kekahi mau ʻāpana i hoʻokahi chip, ʻae lākou i nā hāmeʻa uila e liʻiliʻi, hana maikaʻi, a hoʻohana i ka mana liʻiliʻi. Ke hoʻohana nei ka hapa nui o nā ʻōnaehana uila i nā IC ma ke ʻano he mea kūkulu hale nui, e hoʻololi i ka ʻāpana uila.

Hele mai nā IC i nā ʻano like ʻole, i manaʻo ʻia kēlā me kēia no ka hoʻohana a me ke kumu. Eia kekahi mau ʻano IC kaulana:

Nā MCU: Aia kēia mau kaapuni i hoʻohui ʻia i kahi microprocessor core, hoʻomanaʻo, a me nā peripheral āpau ma ka pahu hoʻokahi. Hāʻawi lākou i ka naʻauao a me ka mana a hoʻohana ʻia i nā ʻōnaehana hoʻopili like ʻole.

Hoʻohana nā lolouila a me nā ʻōnaehana paʻakikī ʻē aʻe i nā microprocessors (MPUs) ma ke ʻano he kikowaena kaʻina hana (CPU). Lawe lākou i nā helu helu a me nā kuhikuhi no nā hana like ʻole.

Hoʻolālā ʻia nā DSP ICs no ka hana ʻana i nā hōʻailona kikohoʻe, e like me nā kahawai leo a me nā wikiō. Hoʻohana pinepine ʻia lākou i nā noi e like me ka hoʻoili kiʻi, nā mea leo, a me ke kelepona.
Nā Kaapuni Hoʻohui Kūikaʻi Kūikawā (ASIC): Ua hana kūikawā ʻia nā ASIC i nā kaapuni i hoʻohui ʻia i manaʻo ʻia no kekahi mau hoʻohana a i ʻole kumu. Hāʻawi lākou i ka hana maikaʻi loa no kahi kumu kikoʻī a loaʻa pinepine i nā mea loea e like me nā ʻōnaehana pūnaewele a me nā mea lapaʻau.

ʻO Field-Programmable Gate Arrays, a i ʻole FPGA, he polokalamu kaʻa i hoʻohui ʻia i hiki ke hoʻonohonoho ʻia e hana i nā hana kūikawā ma hope o ka hana ʻia ʻana. Hiki iā lākou ke hoʻololi a he nui nā koho reprogramming.

Analog integrated circuits (ICs): Hoʻohana kēia mau mea hana i nā hōʻailona hoʻomau a hoʻohana ʻia i ka hoʻoponopono ʻana i ka voltage, amplification, a me nā noi kānana. ʻO nā mea hoʻoponopono Voltage, nā mea hoʻonui leo, a me nā mea hoʻonui hana (op-amps) kekahi mau laʻana.
Hiki i nā IC me ka hoʻomanaʻo ke mālama a lawe i ka ʻikepili. ʻO ka hoʻomanaʻo heluhelu-wale nō e hiki ke hoʻopau uila (EEPROM), hoʻomanaʻo Flash, Static Random Access Memory (SRAM), a me Dynamic Random Access Memory (DRAM) kekahi mau laʻana.

Nā IC i hoʻohana ʻia i ka hoʻokele mana: ʻO kēia mau IC e hoʻomalu a hoʻoponopono i ka mana i hoʻohana ʻia i nā mea uila. ʻO ka mana lako mana, ka hoʻouka ʻana i ka pākaukau, a me ka hoʻololi ʻana i ka uila kekahi o nā hana a lākou e hoʻohana ai.

Hiki i kēia mau kaapuni i hoʻohui ʻia (ICs) i ka loulou ma waena o nā kikowaena analog a me nā kikohoʻe ma o ka hoʻololi ʻana i nā hōʻailona analog i kikohoʻe a me ka hope. Ua ʻike ʻia lākou ʻo nā mea hoʻololi analog-to-digital (ADC) a me nā mea hoʻololi digital-to-analog (DAC).

He liʻiliʻi wale nō kēia, a ʻo ke kahua o nā kaʻa puni i hoʻohui ʻia (ICs) he ākea ākea a hoʻomau i ka ulu ʻana i nā noi hou a me nā holomua ʻenehana.
Kāhea iā mā˚ouno ka ʻike hou aku e pili ana i nā kukui LED strip.
