TLC69611QPWPRQ1

Overview

The TLC69611QPWPRQ1 is an automotive-grade LED lighting driver IC designed for mini-LED matrix local dimming applications. It features a 16-channel integrated current sink architecture with a maximum output current of 60 mA per channel. The device operates on a PWM topology and supports an input voltage range from 3 V to 5.5 V, while delivering a maximum output voltage of 50 V. It functions within a temperature range of -40°C to +125°C and utilizes a 28-pin HTSSOP package.

Feature Summary

• Integrated 16-channel current sink architecture for precise local dimming control
• Automotive qualification compliant for harsh environment reliability
• Supports high-frequency PWM operation for flicker-free display performance

Applications

• Mini-LED matrix backlight systems in automotive displays
• Local dimming controller circuits for vehicle infotainment screens
• High-contrast LCD backlight drivers requiring individual zone control

Procurement Notes

Verify the complete part number including suffixes such as PWPRQ1 to ensure correct packaging and automotive grade specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference datasheet revisions to validate pinout compatibility with existing designs.

Selection Notes

Select this component when designing automotive displays requiring localized brightness adjustment via mini-LED arrays. The 60 mA per channel capability suits medium-density LED matrices. Consider the 50 V output limit for series string configurations. The HTSSOP-28 package offers thermal efficiency for compact board layouts. Verify interface compatibility with host microcontrollers for PWM signal generation.

Part Context

This device belongs to the TLC696x1-Q1 family of automotive LED drivers. It shares the 16-channel current sink topology with peers like the TLC69662QPWPRQ1 but differs in specific electrical ratings and feature sets. The QPWRQ1 suffix indicates automotive qualification and tape-and-reel packaging. It complements boost drivers by providing the sinking stage for complete backlight control loops.

Replacement Considerations

Direct substitutes include other members of the TLC696x1-Q1 family with identical pinouts and channel counts. Verify that alternative parts match the 60 mA output current and 50 V voltage limits. Check for functional equivalence in PWM control interfaces and thermal performance characteristics before substitution.
