TLC6C5716QDAPRQ1

Overview

The TLC6C5716QDAPRQ1 is an automotive-grade LED lighting driver IC featuring 16 constant-current-sink output channels. It supports a maximum output current of 50 mA per channel and handles up to 8 V output voltage. The device operates on a 3 V to 5.5 V supply, utilizing a boost topology with an 8 MHz switching frequency. It offers PWM dimming capabilities and full diagnostics within a 38-HTSSOP package. Qualified under AEC-Q100 for Grade 1, it functions reliably between -40°C and +125°C.

Feature Summary

• Provides 16 independent constant-current sink channels for precise LED control
• Integrates full diagnostic features to monitor open-load and short-to-ground conditions
• Supports linear PWM dimming for high-resolution brightness adjustment

Applications

• Automotive interior ambient lighting systems
• Exterior vehicle headlamp modules
• High-intensity discharge (HID) lamp ballast drivers

Procurement Notes

Verify the specific suffix 'QDAPRQ1' matches the required tape-and-reel packaging format and HTSSOP-38 thermal performance needs. Confirm AEC-Q100 Grade 1 qualification aligns with the target automotive reliability standards. Ensure input voltage ranges fit the 3 V to 5.5 V specification during system integration.

Selection Notes

Select this component when a high-channel-count solution with integrated diagnostics is required for automotive environments. The 50 mA sink capability suits standard automotive LED arrays. Consider the 38-pin HTSSOP footprint for PCB layout constraints. Validate that the boost topology meets the system's inductive design requirements compared to linear alternatives.

Part Context

This part belongs to the Texas Instruments TLC6C5716 family of automotive LED drivers. It is designed specifically for demanding vehicular applications requiring robust fault detection and multiple channel control. The Q1 suffix indicates automotive qualification, distinguishing it from commercial variants while maintaining compatibility with standard automotive communication protocols.

Replacement Considerations

Direct substitutes include other Texas Instruments 16-channel automotive LED drivers such as the TLC6C5916Q or similar series members. Verify pinout compatibility and diagnostic feature parity before substitution. Cross-reference thermal resistance values in the HTSSOP-38 package to ensure equivalent heat dissipation performance.
