LED显示屏驱动芯片

TM1818是LED显示面板设计的驱动IC，它内建的CMOS位移寄存器与锁存功能，可以将串行的输入数据转换成平行输出数据格式。TM1818具有16个电流源，可以在每个输出端口提供2~60mA恒定电流量以驱动LED，每个OUT驱动通道输出可短接后得到更大的电流输出，且当环境发生变化时，对其输出电流影响很小。同时可以选用不同阻值（REXT）的外接电阻来调整TM1818各输出端口的电流大小，因此，可精确地控制LED的发光亮度，适用于高质量白平衡显示驱动模组。本产品性能优良、质量可靠。 • 16 个恒流源输出通道 \n\n• 电流输出大小不因输出端负载电压变化而变化\n\n• 恒流电流范围值，2~60mA@VDD=5V；2~45mA@VDD=3.3V\n\n\n\n\t• 极为精确的电流输出值，\n\n\n\n\n\t（通道与通道）最大误差：≤ ± 1.5％，\n\n\n\n\n\t（芯片与芯片）最大误差：≤ ± 2.0％\n\n\n• 通过调节外部电阻，可设定电流输出值\n\n• 高达 25MHz 时钟频率\n\n• 工作电压：3.0V～5.5Ｖ\n\n• 封装形式：SSOP24、QSOP24;
