Overview
The TLC5941RHBR is a Texas Instruments LED display driver featuring 16 constant-current sink channels. It utilizes a VQFN-32 package and operates within a supply voltage range of 3 V to 5.5 V. The device supports 12-bit grayscale PWM control for precise brightness adjustment and includes dot correction capabilities to ensure uniform LED intensity across all outputs. It functions with a serial interface and offers an output voltage capability of up to 17 V, suitable for various LED lighting applications.
Feature Summary
- Integrates 16-channel constant-current sinks with 12-bit grayscale PWM dimming
- Includes internal dot correction circuitry for consistent luminance across channels
- Features fault detection mechanisms including open and short LED diagnostics
Applications
- LED backlighting systems
- General indicator lighting arrays
- Signage and display modules
Procurement Notes
Verify the specific suffix 'RHBR' corresponds to the tape-and-reel packaging variant when sourcing. Confirm that the component meets RoHS compliance requirements for your assembly process. Ensure the ordering part number matches the exact package type and temperature rating specified in the official datasheet to avoid integration errors.
Selection Notes
Select this component when a high channel count with individual current control is required without external multiplexing. It is appropriate for designs needing precise grayscale control and built-in error checking. Consider the thermal performance of the VQFN-32 package relative to the total power dissipation of the connected LEDs.
Part Context
This part belongs to the TLC5941 series of LED drivers from Texas Instruments. It shares functional similarities with other members like the TLC59401 but differs in specific interface or feature sets. The RHBR designation indicates a specific reel-based packaging format intended for automated surface-mount assembly processes.
Replacement Considerations
Direct substitutes include the TLC5941RHBT for different packaging options. Cross-reference with the TLC5941NT or TLC5941PWP if through-hole or PowerTSSOP packages are required instead of the VQFN form factor.
