TLC5958
ZHCSCU5A–MAY2014–REVISEDSEPTEMBER2014
TLC5958具有预充电场效应晶体管(FET)、LED开路检测功能和显示数据存储器
且支持32路多路复用的48通道16位ES-PWMLED驱动器
1特性
•148通道恒流灌电流输出•具有最大亮度控制(BC)/最大颜色亮度控制(CC)数
据的灌电流：–5VCC时为25mA–3.3VCC时为20mA•全局亮度控制(BC)：3位（8步长）•每个颜色组的颜色亮度控制(CC)：9位（512步长），三组•使用多路复用增强型光谱(ES)PWM进行灰度(GS)控制：16位•支持32路多路复用的48K位灰度数据存储器•LED电源电压高达10V•=3.0V至5.5V•恒流精度–通道之间=±1%（典型值），±3%（最大值）–器件之间=±1%（典型值），±2%（最大值）•数据传输速率：25MHz•灰度时钟频率：33MHz•LED开路检测(LOD)•热关断(TSD)•IREF电阻器短路保护(ISP)•可快速恢复的节能模式(PSM)•延迟开关可防止浪涌电流•预充电FET可避免重影现象
•工作温度范围：-40°C至+85°
C 2应用范围 •采用多路复用系统的LED视频显示屏•采用多路复用系统的LED信号板•高刷新率、高密度的LED面板 3说明 TLC5958是一款48通道恒流灌电流驱动器，适用于占空比为1至32的多路复用系统。
每个通道都具有单独可调的65536步长脉宽调制(PWM)灰度(GS)。
采用48K位显示存储器以提升视觉刷新率，同时降低GS数据写入频率。
输出通道分为三组，每组含16个通道。
各组都具有512步长颜色亮度控制(CC)功能。
全部48通道的最大电流值可通过8步长全局亮度控制(BC)功能设置。
CC和BC可用于调节LED驱动器之间的亮度偏差。
可通过一个串行接口端口访问GS、CC和BC数据。
