Product Summary

The TLC5951RHAR 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. Applications are (1)Full-color LED displays; (2)LED signboards.
