LED裝飾驅動IC

產品應用概(gai)述

應用于固態照(zhao)明如LED照(zhao)明,路燈(deng)照(zhao)明,景(jing)觀照(zhao)明,電(dian)視(shi)系(xi)(xi)統,家庭影院系(xi)(xi)統,便攜式投影儀,汽車儀表顯示器的背光等。

三通(tong)道LED（發光(guang)二極管顯示器）驅(qu)動控(kong)(kong)制(zhi)電(dian)(dian)路(lu)，內部集成有MCU數(shu)(shu)字(zi)接(jie)口、數(shu)(shu)據(ju)(ju)鎖存器、LED高(gao)壓(ya)驅(qu)動等電(dian)(dian)路(lu)。通(tong)過外圍MCU控(kong)(kong)制(zhi)實現該芯片的(de)(de)單(dan)(dan)獨輝(hui)度、級(ji)聯(lian)控(kong)(kong)制(zhi)實現戶外大(da)屏(ping)的(de)(de)彩色點(dian)陣發光(guang)控(kong)(kong)制(zhi)。本產品采用高(gao)壓(ya)功率CMOS工藝，輸(shu)(shu)出端口耐壓(ya)24V，調節(jie)電(dian)(dian)路(lu)（256級(ji)可調）,單(dan)(dan)線(xian)串行接(jie)口級(ji)聯(lian)接(jie)口協議，能通(tong)過一根信(xin)號線(xian)完(wan)成數(shu)(shu)據(ju)(ju)的(de)(de)接(jie)收與(yu)解碼(ma)，內置RC振(zhen)蕩方式,并根據(ju)(ju)數(shu)(shu)據(ju)(ju)線(xian)上(shang)信(xin)號進行時(shi)鐘同步，在接(jie)受完(wan)本單(dan)(dan)元的(de)(de)數(shu)(shu)據(ju)(ju)后(hou)能自動將后(hou)續(xu)數(shu)(shu)據(ju)(ju)整形后(hou)通(tong)過數(shu)(shu)據(ju)(ju)輸(shu)(shu)出端發送(song)出去，內置上(shang)電(dian)(dian)復(fu)位電(dian)(dian)路(lu)，PWM控(kong)(kong)制(zhi)端能夠實現1024級(ji)調節(jie)，掃(sao)描頻率不(bu)低(di)于(yu)400hz/s，芯片間傳輸(shu)(shu)電(dian)(dian)纜不(bu)大(da)于(yu)1米(mi)時(shi)級(ji)聯(lian)個數(shu)(shu)不(bu)小(xiao)于(yu)512。芯片間傳輸(shu)(shu)電(dian)(dian)纜不(bu)大(da)于(yu)3米(mi)時(shi)級(ji)聯(lian)個數(shu)(shu)不(bu)小(xiao)于(yu)256，數(shu)(shu)據(ju)(ju)發送(song)速度可達400Kbps，封裝形式：SOP8

產品特性

3路恒壓驅(qu)動(dong),單線(xian)級(ji)聯(lian),灰度256級(ji)可調(diao),工作電壓6~24V

應用說(shuo)明(ming)

可廣泛應用于(yu)

戶(hu)外彩色(se)LED裝飾

戶(hu)外(wai)大屏

交通信號(hao)指示(shi)

彩色裝飾(shi)燈(deng)線(xian)
