TLC5923RHBTG4

Overview

The TLC5923RHBTG4 is a 16-channel constant-current sink LED driver manufactured by Texas Instruments. It operates with a supply voltage range of 3.0 V to 5.5 V and supports a data transfer rate of 30 MHz. Each channel provides an On/Off state control and features 128-step adjustable constant current sink capability for dot correction. The device delivers up to 80 mA output current per channel and is housed in a 32-pin VQFN (5x5) package.

Feature Summary

• Provides 16 independent channels for constant-current LED sinking
• Includes 128-step adjustable current control for precise dot correction
• Supports high-speed 30 MHz serial data transfer
• Operates within a standard 3.0 V to 5.5 V supply voltage range

Applications

• LED display panels requiring uniform brightness
• Segmented LED indicators with individual intensity control
• Portable electronic devices with limited power budgets
• Consumer electronics featuring multi-zone lighting

Procurement Notes

Verify the complete part number including the suffix G4, which indicates tape and reel packaging, against your specific manufacturing requirements. Confirm that the 32-pin VQFN footprint matches your PCB layout design. Ensure that the 3.0 V to 5.5 V operating voltage aligns with your system's power rail specifications before finalizing procurement orders.

Selection Notes

Select this component when 16 individually addressable constant-current outputs are required for LED arrays. The integrated dot correction feature makes it suitable for applications demanding high visual uniformity across multiple LEDs. Consider the 30 MHz interface speed if rapid data updating is necessary. The low supply voltage range supports battery-operated systems where power efficiency is critical.

Part Context

This part belongs to the TLC5923 family of LED drivers from Texas Instruments. The family focuses on providing reliable constant-current sinking for various LED configurations. The RHBTG4 designation specifies the specific package type, temperature rating, and reel packaging format offered by the manufacturer for surface-mount assembly processes.

Replacement Considerations

Consult official Texas Instruments documentation for direct pin-compatible substitutes. Verify electrical parameters such as current sink limits and supply voltage ranges when evaluating alternative components. Ensure that any replacement maintains the 16-channel architecture and dot correction capabilities required by the original design.
