Overview
The TLC5951TDA2 is a 24-channel, 12-bit PWM LED driver die from Texas Instruments. It features 7-bit dot correction and 3-group, 8-bit global brightness control. The device supports serial data input and includes fault detection capabilities such as LED open and short-to-ground detection. Operating voltage ranges from 3V to 5.5V with a maximum output current of 40mA per channel.
Feature Summary
- Provides 24 independent channels for high-resolution LED dimming
- Integrates 7-bit per-channel dot correction for color uniformity
- Supports 3-group global brightness control via 8-bit resolution
- Includes hardware fault detection for open and short circuits
Applications
- High-density LED display panels
- LED backlighting systems requiring precise color matching
- Architectural lighting control modules
- Automotive interior illumination interfaces
Procurement Notes
Verify the specific die configuration and substrate requirements before integration. Confirm that the application board supports direct die attachment or appropriate packaging solutions. Ensure thermal management strategies align with the power dissipation characteristics of the bare die format. Cross-reference the ordering suffix with official Texas Instruments documentation to confirm pinout and electrical specifications match the design intent.
Selection Notes
Select this component when multi-channel LED control with high precision is required in a compact form factor. The integrated dot correction simplifies calibration processes compared to drivers without this feature. Consider the serial interface speed and pin count constraints of the host microcontroller. Evaluate the need for group-based brightness control versus individual channel adjustment for the specific lighting application.
Part Context
This part belongs to the TLC5951 family of LED drivers designed for applications demanding high channel counts and accurate color reproduction. The TDA2 suffix indicates a specific die variant within the broader product line. It complements other Texas Instruments LED solutions by offering a balance between resolution and channel density for professional lighting displays.
Replacement Considerations
Direct substitutes include other variants within the TLC5951 series such as the TLC5951DAP or TLC5951RTAR, provided the package type matches the assembly process. Verify functional equivalence regarding dot correction bits and group configurations. Consult the manufacturer's cross-reference guide for compatible alternatives with identical electrical parameters.
