I-Slkor namuhla yethula i-SL4275, isilawuli sikagesi esiqinile esingu-5V low-dropout (LDO) esidizayinelwe amasistimu ezimoto nawezimboni adinga ukubekezelela amandla kagesi aphezulu. Le divayisi ye-monolithic 5-pin TO-package isekela okokufaka okungafika ku-55V futhi iletha u-450mA wokukhiphayo wamanje, okufaka phakathi ukuvikelwa kokusetha kabusha kwesekethe emfushane, izinga lokushisa elingaphezu kwamandla, kanye ne-undervoltage ehlanganisiwe. Iklanyelwe ukwethembeka ezindaweni ezinokhahlo, i-SL4275 iqondise izinhlelo zokusebenza ezifana ne-infotainment, i-ADAS, amamojula okulawula umzimba, namasistimu wamandla ezimboni afaka amathuluzi amandla namaphakethe ebhethri.

Ukusebenza Okubalulekile Kwezicelo Ezifunayo

Ezimeni zezimoto, ukulawulwa kwamandla kagesi okuzinzile ngesikhathi sezimo ezibandayo kanye nezikhathi zokulayisha kubalulekile. I-SL4275 iqinisekisa ukunemba kokuphumayo okungu-±2% (igama elingu-5.0V) nge-ultra-low quiescent current (80μA), inciphisa ukuphuma kwamandla kumasistimu ahlala evuliwe. Umsebenzi wayo wokusetha kabusha ozinikele uqapha ukuqina kokuphumayo: uma i-VQ iwela ngaphansi kuka-4.65V, iphinikhodi ye-RQ igomela isignali yokusetha kabusha yezinga eliphansi, nesikhathi sokulibaziseka esihlelekayo nge-capacitor yangaphandle (iphinikhodi ye-D). Lokhu kuvikela izilawuli ezincane kanye nezindawo zokuxhumana phakathi nemicimbi ye-brown-out.

Ukuvikelwa Okuphelele Kobuqotho Besistimu

I-SL4275 ihlanganisa ukuvikelwa kwezendlalelo eziningi ukuphatha izingozi zikagesi wezimoto:

● Ukuqina kwebhethri/ukuqina kwaphansi ngokusebenzisa isilawuli esikhawulelayo samanje nokuvalwa kwe-thermal

● Hlehlisa ukuvinjwa kwamanje ngedizayini yangaphakathi ye-MOS

● Ukuqinisekisa ukuzinza ngama-capacitor okukhiphayo (CQ ≥ 22μF, ESR ≤ 5Ω)

● Isinxephezelo sokulandelela esiqinile sitholwa kusetshenziswa i-input capacitor (CI), evumela ukusebenza okuthembekile kuwo wonke -40°C kuya +125°C amazinga okushisa e-ambient.

Ukuguquguquka Kwedizayini Okuthuthukisiwe

Amandla kagesi aphansi omlawuli akhulisa ukusebenza kahle kumasistimu axhumeke ngebhethri. Ukuhleleka kwayo kokulibaziseka kokusetha kabusha kusekela ukulandelana kwamandla ngokwezifiso, kuyilapho iphakheji ye-5-pin TO (okuhlukile TO-220/TO-252) inika amandla ukuphathwa okushisayo okuguquguqukayo. Idivayisi ihlangabezana nokuthobelana ne-RoHS futhi ithuthukiselwe imiklamo yezimboni ebambezeleke ngendawo ehlanganisa amabhayisikili e-e nezilawuli ze-telematics.

Umkhiqizo Ukutholakala

I-SL4275 manje isiyatholakala ukuze kwenziwe amasampula, ihlinzeka ngenye indlela engabizi kakhulu kune-Infineon's TLE4275. I-Slkor inikezela ngosekelo olugcwele lobuchwepheshe lokuhlanganiswa kwedizayini eqondise kuzixazululo zamandla afanelekayo ezimoto.

Mayelana SLKOR:

SLKOR, enekomkhulu e-Shenzhen, e-China, iyibhizinisi kazwelonke elithuthuka ngokushesha elithuthukayo emkhakheni we-semiconductor yamandla. Njengoba kunezikhungo ze-R&D e-Beijing nase-Suzhou, ithimba layo lezobuchwepheshe eliyinhloko lisuka eNyuvesi yaseTsinghua. Njengomsunguli we-silicon carbide (SiC) ubuchwepheshe bedivayisi yamandla, SLKORImikhiqizo isetshenziswa kakhulu ezimotweni zamandla amasha, ukukhiqiza amandla kagesi e-photovoltaic, i-IoT yezimboni, kanye nezinto zikagesi zabathengi, ihlinzeka ngezixazululo ezibalulekile ze-semiconductor kumakhasimende angaphezu kuka-10,000 emhlabeni jikelele.

Le nkampani iletha amayunithi angaphezu kwezigidi eziyizinkulungwane ezimbili ngonyaka, nama-SiC MOSFET ayo kanye nesizukulwane sesi-2 sokululama ngokushesha ama-SBD diode abeka amabhentshimakhi embonini ngesilinganiso sokusebenza kahle kanye nokuzinza okushisayo. SLKOR inamalungelo obunikazi okusungulwa angaphezu kwe-100 futhi inikeza amamodeli wemikhiqizo engu-2,000+, ngokuqhubekayo yandisa iphothifoliyo yayo ye-IP kuwo wonke amadivayisi kagesi, izinzwa, nama-IC okuphatha amandla. Izitifiketi ezihlanganisa i-ISO 9001, i-EU RoHS/REACH, nokuthobelana kwe-CP65 kukhombisa ukuzibophezela okuqinile kwenkampani ekusunguleni okusha kwezobuchwepheshe, ukukhiqiza okunciphile, kanye nentuthuko esimeme.
