LED显示屏驱动芯片

TM1816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。TM1816具有16个电流源，可以在每个输出端口提供3~45mA恒定电流量以驱动LED；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TM1816各输出端口的电流大小，因此，可精确地控制 LED的发光亮度。也可以在每个输出端口串接多个LED。 • 16 个恒流源输出通道 \r\n• 恒流电流范围值: 3~45mA@VDD=5V；3~30mA@VDD=3.3V \r\n• 通过调节外部电阻，可设定电流输出值 \r\n• 工作电压范围：3.3V～5V \r\n• 封装形式：SSOP24;
