Overview
The TLC5951DAP is a 24-channel, 12-bit PWM LED driver manufactured by Texas Instruments. It features 7-bit dot correction and 8-bit global brightness control for precise color and intensity management. The device operates on a serial data input mode with a maximum operating frequency of 30 MHz. It supports an input voltage range from 3 V to 5.5 V and provides a constant current output capability of 40 mA per channel. The component is housed in a 38-pin HTSSOP package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates 7-bit dot correction and 8-bit global brightness control for accurate LED uniformity.
- Provides 24 channels of 12-bit PWM resolution for high-fidelity dimming.
- Includes fault detection mechanisms such as LED open and short-to-ground detection.
Applications
- High-density LED display panels requiring precise color calibration
- LED backlighting systems for industrial or commercial displays
- General-purpose LED lighting control circuits
Procurement Notes
Verify the specific package variant, as the DAP suffix denotes a 38-pin HTSSOP tube packaging. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments. Ensure the ordering part number matches the required tape-and-reel or tube configuration for your assembly process.
Selection Notes
Select this component when 24 independent channels with individual dot correction are required. It is suitable for designs needing 12-bit grayscale resolution without external microcontrollers for PWM generation. Consider the thermal performance of the HTSSOP package if driving multiple channels at maximum current simultaneously.
Part Context
This part belongs to the TLC5951 series of LED drivers from Texas Instruments. It is designed to simplify the interface between digital controllers and large arrays of LEDs. The series emphasizes ease of use through serial data inputs and integrated error reporting capabilities.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing PCB footprints and software drivers before considering alternative components.
