具有全局亮度控制、LED 开路/短路检测功能和省电模式的 48 通道 LED 驱动器

TLC5954 是一款 48 通道，恒定灌电流 LED 驱动器。 可通过向内部寄存器写入数据来打开或关闭每条通道。 输出通道 (OUTX)被分为三组，每组 16 条通道。 每个通道组（R，G 和 B）具有 128 步长全局亮度控制 (BC) 功能。 所有 48 个通道的最大电流值可由 8步长最大电流控制 (MC) 功能进行设置。 此器件具有两个错误标志：LED 开路检测 (LOD) 和 LED 短路检测 (LSD)。错误标志可由串行接口端口读取。 此器件还有一个省电模式，此模式在所有输出关闭时将总流耗设定为7µA（典型值）。要了解所有可用封装，请见数据表末尾的可订购产品附录。 • 48 个恒定灌电流输出通道 具有开关控制功能\n• 32 通道为 34.9mA\n• 没有针对电流设置的外部电阻器\n• 针对每个色彩组的全局亮度控制 (BC)：7 位（128 个步长），3 组\n• VCC = 3.0V 至 3.6V\n• 通道到通道 = ±1%（典型值），±3%（最大值）\n• 数据传输速率：30MHz\n• LED 开路检测 (LOD)\n• 省电模式 (PSM)：流耗 7µA，高速恢复\n• 延迟开关最大限度地减少涌入电流\n• 工作温度范围：-40°C 至 +85°C;
