TLC59283 (正在供货) 具有预充电 FET 的 16 通道恒流 LED 驱动器

 

描述

TLC59283 是一款 16 通道、恒定电流吸收发光二极管 (LED) 驱动器。 每个通道可由一个与 3.3V 或者 5V CMOS 逻辑电平兼容(取决于运行 VCC)的简单串行通信协议控制。 当串行数据缓冲区被载入时,一个锁存脉冲 (LAT) 上升边沿将数据转移到 OUT输出。 BLANK 引脚可被用于关闭加电和输出数据锁存期间的的所有 OUT输出以防止此时间段内不必要的图像显示。 所有 16 个通道的恒定电流值有一个单一外部电阻器设定。

每个恒定电流输出有一个预充电场效应晶体管 (FET),此晶体管能够减少复用(动态)驱动 LED 显示时的重影。 可将多个 TLC59283 级联在一起以控制来自同一处理器的额外的 LED。
