说明

TLC6C5748-Q1 是一款 48 通道、恒定灌电流驱动器。每个通道具有一个独立可调节,脉宽调制 (PWM),灰度 (GS) 亮度控制,此控制有 65,536 步长和 128 步长的恒定电流点校正 (DC)。DC 可调节通道间的亮度偏差。所有通道具有一个 128 步长的全局亮度控制 (BC)。BC 调节 R,G,B 色彩组之间的亮度偏差。8 步长最大电流控制 (MC) 为每个色彩组的所有通道选择最大输出电流范围。可通过一个串行接口端口来访问 GS,DC,BC 和 MC 数据。

TLC6C5748-Q1 有三个错误标签:LED 开路检测 (LOD)、LED 短路检测 (LSD) 和热关断 (TSD)。可使用一个串行接口端口来读取错误检测结果。
