TLC6C5724QDAPRQ1

Overview

The TLC6C5724QDAPRQ1 is an automotive-grade, 24-channel constant-current LED driver featuring full diagnostics and boost topology. It operates within a supply voltage range of 3 V to 5.5 V, delivering up to 50 mA per channel with a maximum output voltage of 8 V. The device supports PWM dimming at frequencies up to 8 MHz and includes 7-bit dot correction for uniformity. Designed for Grade 1 temperature conditions, it functions reliably from -40°C to +125°C ambient temperature. Packaged in a 38-pin HTSSOP (DAP) format, it meets AEC-Q100 standards for automotive reliability.

Feature Summary

• Provides 24 independent constant-current sink channels with integrated full diagnostic capabilities for fault detection.
• Incorporates 7-bit dot correction and 12-bit PWM dimming to ensure precise LED brightness control and color uniformity.
• Features a boost converter topology enabling operation with high-voltage LED strings while maintaining efficient current regulation.

Applications

• Automotive exterior lighting systems requiring multi-channel RGB or white LED control
• Adaptive driving beams and matrix headlamp modules
• Interior ambient lighting with high-density channel requirements

Procurement Notes

Verify the complete part number including suffixes such as DAPRQ1 to confirm package type and tape-and-reel configuration. Ensure compatibility with automotive grade specifications by checking AEC-Q100 certification status. Confirm operating temperature range requirements match the specified Grade 1 limits. Validate input voltage constraints against system power supply rails before integration.

Selection Notes

Select this component when designing automotive lighting systems requiring high channel density and comprehensive fault monitoring. The boost topology is suitable for applications where LED forward voltage exceeds the supply rail. Consider the 38-pin HTSSOP package for space-constrained PCB layouts. Evaluate thermal performance requirements given the high channel count and continuous current drive capability.

Part Context

This device belongs to the Texas Instruments TLC6C5724-Q1 family of automotive LED drivers. It shares functional similarities with other members like the TLC6C5716-Q1 but offers increased channel count. The series is designed specifically for demanding automotive environments requiring robust diagnostics and precise light control.

Replacement Considerations

Direct substitutes include other parts within the TLC6C5724-Q1 family with compatible pinouts and electrical characteristics. Verify that alternative components support the required 24-channel configuration and boost topology. Check for equivalent AEC-Q100 qualification and temperature rating compliance.
