TLC5951 具有 7 位点校正和 3 组 8 位全局亮度控制功能的 24 通道、12 位 PWM LED 驱动器

TLC5951 描述

The TLC5951 is a 24-channel, constant-current sink driver. Each channel has an individually-adjustable, 4096-step, pulse width modulation (PWM) grayscale (GS) brightness control and 128 step constant-current dot correction (DC). The dot correction adjusts brightness deviation between channels and other LED drivers. The output channels are grouped into three groups of eight channels. Each channel group has a 256-step global brightness control (BC) function and an individual grayscale clock input. GS, DC, and BC data are accessible via a serial interface port. DC and BC can be programmed via a dedicated serial interface port. The TLC5951 has three error detection circuits for LED open detection (LOD), LED short detection (LSD), and thermal error flag (TEF).
