LED顯示屏驅(qū)動(dòng)芯片

TM1818是LED顯示面板設(shè)計(jì)的驅(qū)動(dòng)IC，它內(nèi)建的CMOS位移寄存器與鎖存功能，可以將串行的輸入數(shù)據(jù)轉(zhuǎn)換成平行輸出數(shù)據(jù)格式。TM1818具有16個(gè)電流源，可以在每個(gè)輸出端口提供2~60mA恒定電流量以驅(qū)動(dòng)LED，每個(gè)OUT驅(qū)動(dòng)通道輸出可短接后得到更大的電流輸出，且當(dāng)環(huán)境發(fā)生變化時(shí)，對(duì)其輸出電流影響很小。同時(shí)可以選用不同阻值（REXT）的外接電阻來調(diào)整TM1818各輸出端口的電流大小，因此，可精確地控制LED的發(fā)光亮度，適用于高質(zhì)量白平衡顯示驅(qū)動(dòng)模組。本產(chǎn)品性能優(yōu)良、質(zhì)量可靠。 ? 16 個(gè)恒流源輸出通道 \n\n? 電流輸出大小不因輸出端負(fù)載電壓變化而變化\n\n? 恒流電流范圍值，2~60mA@VDD=5V；2~45mA@VDD=3.3V\n\n\n\n\t? 極為精確的電流輸出值，\n\n\n\n\n\t（通道與通道）最大誤差：≤ ± 1.5％，\n\n\n\n\n\t（芯片與芯片）最大誤差：≤ ± 2.0％\n\n\n? 通過調(diào)節(jié)外部電阻，可設(shè)定電流輸出值\n\n? 高達(dá) 25MHz 時(shí)鐘頻率\n\n? 工作電壓：3.0V～5.5Ｖ\n\n? 封裝形式：SSOP24、QSOP24;
