具有 7 位全局亮度控制、省电模式和自诊断功能的 16 通道恒流 LED 驱动器

TLC5929 是 16 通道恒定电流汇极 LED 驱动器。 可通过向内部寄存器写入数据对每一通道进行开关操作。 所有 16 个通道的恒定电流值都由单个外部电阻器设置，此电阻器支持 128 步全局亮度控制 (BC)。 TLC5929 具有六个错误标记：LED 开路检测 (LOD)、LED 短路检测(LSD)、输出漏电检测 (OLD)、参考电流端接短路检测 (ISF)、预热报警 (PTW) 以及散热故障标记 (TEF)。 此外，LOD 和 LSD 功能还提供无形检测模式 (IDM)，可在输出关闭时检测这些故障。 故障检测结果可通过串行接口端口读取。 TLC5929 还具有省电模式，可在全部输出关 • 16 个支持开关控制的恒定电流汇极输出通道\n• 40 mA (VCC ≤ 3.6 V)\n• 全局亮度控制： 7 位（128 步）\n• LED 电源电压： 高达 10 V\n• 通道间 = ±1% （典型值），±3% (最大值)\n• 数据传输速率： 33 MHz\n• 支持无形检测模式的 LED 开路检测 (LOD)/LED 短路检测\n• 预热报警 (PTW)\n• 电流参考端接短路标记 (ISF)\n• 欠压锁定可设置默认数据\n• 工作温度范围： –40°C 至 +85°C;
