Overview
The TLC69664QPWPRQ1 is an automotive-grade LED lighting driver IC designed for 64 mini-LED matrix local dimming applications. It features a 28-pin HTSSOP package and operates within a supply voltage range of 3 V to 5.5 V. The device provides 16 independent output channels, each capable of delivering up to 60 mA of output current with a maximum output voltage of 50 V. It supports PWM dimming topology and functions reliably across an operating temperature range from -40°C to +125°C.
Feature Summary
- Supports 64 mini-LED matrix configurations through cascading capabilities
- Provides independent 16-channel control for precise local dimming
- Automotive qualified for high reliability in vehicle environments
Applications
- Automotive LCD local dimming backlight drivers
- Mini-LED matrix lighting systems
- High-end automotive display modules
Procurement Notes
Verify the complete part number including suffixes such as PWPRQ1 to ensure correct packaging and automotive qualification status. Confirm RoHS compliance and humidity sensitivity levels prior to assembly. Cross-reference the specific datasheet revision to validate electrical characteristics against your design requirements. Ensure compatibility with your system's communication interface protocols before finalizing procurement.
Selection Notes
Select this component when designing automotive displays requiring localized brightness control for enhanced contrast. It is suitable for systems needing 16 independently controllable outputs per unit. Consider the HTSSOP package constraints for PCB layout. Evaluate thermal management needs given the 125°C maximum junction temperature rating and 60 mA per channel capability.
Part Context
This device belongs to the TLC6966x-Q1 series of LED drivers from Texas Instruments. It shares architectural similarities with models like the TLC69662 and TLC69668 but is specifically configured for 64-zone matrix applications. The Q1 suffix indicates automotive qualification, distinguishing it from consumer-grade variants in the broader family.
Replacement Considerations
Direct substitutes include other members of the TLC6966x-Q1 family, such as the TLC69662QPWPRQ1 or TLC69668QPWPRQ1, depending on the required matrix size. Verify pin-to-pin compatibility and software register mapping before swapping.
