Overview
The TLC59116ITPWTQ1 is a 16-channel constant-current LED sink driver designed for automotive applications, certified to AEC-Q100 standards. It features an I2C-compatible interface with Fast-Mode Plus (FM+) support up to 1 MHz. The device provides 16 individually controllable outputs with programmable current levels and includes built-in open-load detection and thermal shutdown protection. Operating from a supply voltage range of 3V to 5.5V, it utilizes a 28-pin TSSOP package with exposed pad for enhanced thermal performance.
Feature Summary
- Automotive-grade reliability with AEC-Q100 qualification
- Fast-Mode Plus I2C interface for high-speed data transmission
- Integrated open-load detection for diagnostic capabilities
- Thermal shutdown protection for operational safety
Applications
- Automotive interior ambient lighting systems
- Instrument cluster backlighting control
- Infotainment display edge lighting
- Door panel and console accent illumination
Procurement Notes
Verify the complete part number including suffixes against official Texas Instruments documentation to ensure correct package type and temperature rating. Confirm AEC-Q100 compliance requirements match specific vehicle application standards. Check for lead-free and RoHS compliance status in the latest datasheet before finalizing procurement specifications.
Selection Notes
Select this component when automotive environmental robustness and precise LED current regulation are required. The FM+ interface allows efficient daisy-chaining of multiple drivers to reduce pin count. Ensure the design accommodates the 28-pin TSSOP footprint and thermal pad soldering requirements for optimal heat dissipation during continuous operation.
Part Context
This device belongs to the TLC5911x family of LED drivers from Texas Instruments. It shares functional similarities with other members like the TLC59116IPWR but differs in automotive certification and specific packaging options. The family focuses on providing flexible LED control solutions with integrated diagnostics for complex lighting architectures.
Replacement Considerations
Direct substitutes include other AEC-Q100 qualified variants within the TLC59116 series such as TLC59116ITPWRQ1. Verify pin compatibility and software register mapping before swapping. Non-automotive equivalents like TLC59116IPWR lack the required qualification for automotive use.
