TLC5923RHBR

Overview

The TLC5923RHBR is a Texas Instruments LED driver IC featuring 16 channels with dot correction capabilities. It utilizes a VQFN-32 package and operates within a supply voltage range of 3 V to 5.5 V. The device supports an operating temperature range from -40°C to +85°C. It is designed for precise LED intensity control through integrated grayscale PWM functionality, ensuring uniform brightness across all outputs without external component requirements.

Feature Summary

• Integrated dot correction mechanism ensures consistent luminance across all sixteen output channels.
• Built-in grayscale pulse-width modulation allows for precise digital intensity control of connected LEDs.
• Simplified interface design reduces external component count by integrating necessary drive circuitry.

Applications

• General-purpose LED lighting arrays requiring uniform brightness
• Backlighting systems for displays and indicators
• Portable electronic devices with limited power budgets

Procurement Notes

Verify the specific suffix 'RHBR' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with your PCB footprint, as the VQFN-32 package requires precise soldering techniques. Cross-reference the RoHS status and lead-free compliance details directly with official documentation before finalizing procurement orders.

Selection Notes

Select this component when 16 individually controllable LED channels are required with built-in brightness uniformity correction. It is suitable for designs needing low external component counts and reliable grayscale performance. Consider thermal management requirements given the VQFN-32 package constraints in high-density applications.

Part Context

This part belongs to the TLC592x series of LED drivers from Texas Instruments, which focuses on providing efficient, multi-channel solutions for lighting applications. The series emphasizes ease of use and reduced bill-of-materials complexity by integrating essential drive functions into a compact form factor suitable for space-constrained electronics.

Replacement Considerations

Consult official substitution guides for equivalent parts within the same family or compatible alternatives. Verify pinout compatibility and electrical characteristics such as current limits and voltage ranges before replacing existing components in established designs.
