具有 6 位全局亮度控制的 16 通道、16 位 PWM LED 驱动器

 

描述

TLC59482 是一款 16 通道,恒定灌电流驱动器。 每个通道有一个步长为 65,536 的独立可调节、脉宽调制 (PWM) 灰度 (GS) 亮度控制。 所有通道具有一个 64 步长的全局亮度控制 (BC)。 BC 调节与其它 LED 驱动器的亮度偏差。 可通过一个串行接口访问 GS,和 BC 数据。

特性

  • 16 个恒定流入电流源输出通道
  • 具有最大亮度控制 (BC) 数据的灌电流能力:
    • 1mA 至 35mA (VCC≤ 3.6V)
    • 1mA 至 45mA (VCC> 3.6V)
  • 全局亮度控制 (BC):
    • 范围为 0% 至 100% 的 6 位(64 步长)(缺省值为 50%)
  • LED 电源电压:高达 10V
  • VCC:3.0V 至 5.5V
  • 恒定电流精度:
    • 通道到通道:±1%(典型值),±2.5%(最大值)
    • 器件到器件:±2%(典型值),±4%(最大值)
  • 数据传输速率:30MHz
  • 灰度控制时钟:33MHz
  • 自动重复显示功能
  • 自动数据刷新
  • 显示计时复位
  • 用来防止涌入电流的 4 通道成组延迟开关
  • 工作温度范围:-40°C 至 +85°C
