TLC5951 - 24-Channel 12-Bit PWM LED Driver

General Description

The TLC5951 device is a 24-channel, constantcurrent sink driver.

Each channel has an individuallyadjustable, 4096-step, pulse-width modulation (PWM) grayscale (GS) brightness control and 128-step constant-current dot correction (DC).

Key Features

  • 1 24-Channel Constant-Current Sink Output.
  • Current Capability: 40 mA.
  • Selectable Grayscale (GS) Control With PWM: 12-Bit (4096 Step), 10-Bit (1024 Step), 8-Bit (256 Step).
  • Three Independent Grayscale Clocks for Three Color Groups.
  • Dot Correction (DC): 7-Bit (128 Step).
  • Global Brightness Control (BC) for Each Color Group: 8-Bit (256 Step).
  • Auto Display Repeat Function.
  • Independent Data Port for GS and BC and DC Data.
