Product Description

The TLC5951DAP is a 24-channel 12-bit PWM constant-current LED Sink Driver for use with LED signboards. Each channel has an individually-adjustable, 4096-step, pulse width modulation (PWM), 8-bit grayscale (GS) brightness control and 7-bit 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. It 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 while LSD detects a shorted LED. TEF indicates an over-temperature condition.
Three independent grayscale clocks for three colour groups
Auto display repeat function
Independent data port for GS and BC/DC data
Communication path between each data port
CMOS logic level I/O
Thermal shutdown (TSD) with auto restart
Grouped delay to prevent inrush current
Constant-current accuracy - ±1.5% channel-to-channel and ±3% device-to-device
Green product and no Sb/Br
