Description
General part information
TLC5951 Series
The TLC5951 device 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 device has three error-detection circuits for LED-open detection (LOD), LED-short detection (LSD), and thermal error flag (TEF). LOD detects a broken or disconnected LED, LSD detects a shorted LED, and TEF indicates an overtemperature condition.
