Texas Instruments TLC5952DAP Product Overview

The TLC5952DAP is a highly versatile LED driver integrated circuit (IC) manufactured by Texas Instruments (TI), designed to manage complex lighting solutions. This component is part of TI's extensive range of power management devices, renowned for their reliability and performance. The TLC5952DAP is particularly suited for applications requiring precise control of multiple LEDs, such as full-color displays, message boards, and various forms of decorative lighting.

Key Features

  • High-Precision LED Control: The TLC5952DAP offers 16 channels of constant-current sink drivers, ensuring uniform and stable LED brightness for each connected diode.
  • Advanced Color Mixing: With its capability to support 65,536 grayscale levels and 128 constant-current output levels, the device enables sophisticated color mixing and fine dimming control, making it ideal for full-color LED displays.
  • Flexible Dot Correction: The built-in dot correction feature allows for individual brightness adjustment of each LED, compensating for variations in color or brightness to achieve uniform output across the display.
  • Energy-Efficient: The TLC5952DAP is designed with energy efficiency in mind, incorporating features like LED open detection and pre-charge FET for reducing power dissipation.
  • Thermal Protection: The device includes thermal shutdown protection to prevent damage from overheating, ensuring a longer lifespan for the LEDs and the driver IC.


Due to its robust feature set and high level of integration, the TLC5952DAP is suitable for a wide range of applications, including:

  • Video and graphic displays
  • Variable message signs (VMS)
  • Commercial and architectural lighting systems
  • Stage and entertainment lighting
  • LED-based decorative and accent lighting

Technical Specifications

The TLC5952DAP operates over a supply voltage range of 3.0 V to 5.5 V and is housed in a HTSSOP-38 package. The device communicates via a serial interface and includes features like grayscale PWM control, built-in error detection, and programmable LED current for each output channel, allowing for a high degree of customization to match specific design requirements.
