I-Slkor SL27517A: Ukumiselela kokungena kwe-TI UCC27517 ene-Enhanced 4A Symmetric Drive

I-SL27517A ye-Slkor yehlisa izindleko ze-BOM ngo-30% uma iqhathaniswa ne-TI UCC27517 kuyilapho inweba ibanga likagesi libe ngu-20V kuzinhlelo zokusebenza ezibucayi zebhethri.

1.1 Igama Lomkhiqizo: SLKOR SL27517A MOSFET Driver Isixazululo

Izicelo: Amathuluzi kagesi, isilawuli semoto, iziguquli ze-AC/DC, isilawuli sezimboni, njll.

2. Ukulinganisa Ukusebenza Nokuhambisana Okuqinile

2.1 Ikhono le-Symmetrical Drive

The SLKOR I-SL27517A, umshayeli wesango lesiteshi esisodwa se-4A, inikeza izinzuzo ezibalulekile lapho ishintsha i-UCC27517DBVR ye-TI. Izinzuzo ezibalulekile zifaka ukuhambisana kokusebenza, ukulawula izindleko, ukuguquguquka kwedizayini, nokuzinza kokunikezela.

I-SL27517A ihlinzeka ngosinki ophakeme ongu-4A/umthombo wamanje (idrayivu elinganayo) ku-VDD=12V, efanayo nekhono le-UCC27517's 4A lomthombo/usinki. Ishayela kahle amadivayisi kagesi afana nama-MOSFET nama-IGBT, iyenze ilungele ukushintsha izinto zikagesi neziguquli ze-DC-DC.

2.2 Ububanzi bamandla kagesi obubanzi

I-SL27517A isebenza ukusuka ku-4.5V ukuya ku-20V, idlula i-UCC27517 (4.5V-18V), ikakhulukazi ithuthukisa ukuguquguquka kuzinhlelo zokusebenza ezisebenzisa amandla kagesi aphansi noma amandla ebhethri (isb, amadivaysi aphathekayo).

2.3 Ukubambezeleka Okuphansi kanye Nokuphendula Ngesivinini

I-SL27517A ifaka ukubambezeleka okufushane kokusabalalisa (uhlobo lwama-12ns) kanye nezikhathi zokuvuka/zokuwa ngokushesha (6ns/11ns), okunciphisa ukulahlekelwa kokushintsha. Lokhu kufanela izinhlelo zokusebenza zemvamisa ephezulu njengamandla edijithali nokushayela kwedivayisi ye-GaN.

3. Ukuguquguquka Komklamo Nokuphepha Okuthuthukisiwe

3.1 Ukucushwa Kokufaka Okukabili kanye Nokusetshenziswa kwamandla

I-SL27517A isekela izindlela zokufaka eziguqukayo (IN-) noma ezingaguquki (IN+). Idizayini yayo enamaphini amabili ivumelana kalula nezimfuneko zokulawula okunengqondo, yenza ukwakheka kwesekethe kube lula.

3.2 Ukuvikelwa Kokufaka Okuntantayo

Uma okokufaka kuntanta, okokukhiphayo kwe-SL27517A kuyehla ngokuzenzakalelayo, kuvimbele ukucupha okungamanga kwamadivayisi kagesi futhi kuthuthukise ukwethembeka kwesistimu.

3.3 I-low Quiscent Yamanje

I-static current encane iyenza ilungele izimo ezisebenza ngamandla ebhethri noma amandla aphansi (isb., izinto zokusebenza zelanga, i-UPS).

4. Ukusetshenziswa Okujwayelekile kwe SLKOR I-SL27517A Kuzimo Zokushayela Ezinamandla Aphezulu

Isimiso sohlelo lokusebenza:

4.1 Isiginali yokushintshashintsha okokufaka inikeza i-PWM waveform ukushayela SLKOR PC817 optocoupler U2. Ezingeni eliphezulu le-pulse engu-24V, i-optocoupler yamanje ingu-~6mA (ishintsheka ngokusebenzisa izinqamuleli ezikhawulelayo zamanje R6/R8 yokulawula okungu-5V). I-U2 inikezela ngokuyinhloko ukuhlukaniswa kwesignali. Amandla we-Optocoupler ahlinzekwa yi- SLKOR LM2596S-5.0 DC-DC ukuphathwa kwamandla IC (5V okukhiphayo). Amasignali okushintshashintsha angaphandle angavela ku-PLC. I-D1 (SLKOR switching diode) isebenza njenge-freewheeling diode, eqhuba ukuvikela i-optocoupler U2 ngesikhathi sokuhlehla kwesignali.

U1 uyi SLKOR SL27517A umshayeli wesango IC—isiteshi esisodwa esingu-4A esinesivinini esiphezulu somshayeli wesango. Ishayela kahle futhi ngokuphepha ama-MOSFET/IGBT. Izici ezifana nokubambezeleka okuphansi kokusabalalisa, iphakheji ye-SOT-23 ehlangene, kanye ne-ultra-low quiescent yamanje inika amandla amafrikhwensi okushintsha e-MOSFET afika kumakhulu ambalwa ama-kHz. Le chip ilungele amadrayivu okulungisa okuvumelanisa kusiphakeli samandla okuxhumana nezinhlelo zokusebenza zezimboni.

4.2 Izincomo zobunjiniyela:

● I-SL27517A inikwa amandla yi-12V kule sekethi. Lapho i-pin 5 iphuma phezulu, ishayela i- SLKOR SL142N06Q MOSFET ukuze uvule umthwalo.

● I-SL142N06Q MOSFET ihlinzeka ngomthombo wamanje we-drain-source we-20A ku-Vgs=10V, nge-2.6mΩ on-resistance (Rds(on)) ephansi, iyenze ibe yinhle kakhulu ekushintsheni kwesivinini esikhulu nokulungiswa okuvumelanayo.

● khetha inani elingu-R3 ngokusekelwe esakhiweni sangempela se-PCB (100Ω ebonisiwe). Beka u-R3 eduze kwesango le-MOSFET elinemikhondo emifushane ukuze unciphise ukungeniswa kwezinambuzane.

● I-D3 (ukushintsha i-diode) isheshisa ukucisha kwe-MOSFET; engeza njengoba kudingeka.

5. SLKOR SL27517A Isango Lomshayeli we-DEMO Ibhodi

● Idizayini ye-PCB enezingqimba ezimbili. Lapho ushayela ama-MOSFET ahambisanayo e-SL142N06Q aphatha izinga eliphezulu lamanje, ibhodi le-DEMO lisebenzisa ukuthululelwa kwethusi kwamandla ezinhlangothi zombili ukuze kukhishwe ukushisa kanye namandla amanje.

● I-CN2/CN1: Xhuma kuphampu yenjini/yelaser.

● I-CN2/CN3: Xhuma ekunikezeni amandla (12V-60V max).

● Ukubambezeleka okuphansi kwe-SL27517A kunika amandla ukusetshenziswa okusabalele ezinhlelweni ze-MOSFET eziqhutshwa yi-PWM ezinamandla amakhulu.

● Izici SLKOR uphawu; skena ikhodi ye-QR ukuze uyilandele SLKOR izibuyekezo.
