Overview
The TLC59116ITPWRQ1 is a 16-channel constant-current LED sink driver designed for automotive applications, certified to AEC-Q100 standards. It features an I2C-compatible Fast-Mode Plus (FM+) interface for control and data transmission. The device provides 16 individually addressable outputs with adjustable current levels up to 120 mA per channel and supports 8-bit linear PWM dimming. It operates within a supply voltage range of 3 V to 5.5 V and includes thermal shutdown protection. The component is housed in a 28-pin TSSOP package.
Feature Summary
- Automotive-grade reliability compliant with AEC-Q100 specifications
- Integrated 16-channel constant-current sink drivers with adjustable output levels
- Fast-Mode Plus (FM+) I2C bus interface for simplified system connectivity
Applications
- Automotive interior ambient lighting systems
- Instrument cluster backlighting
- Infotainment display illumination
Procurement Notes
Verify the specific suffix 'Q1' confirms AEC-Q100 automotive qualification status. Ensure the 'T' indicates tape-and-reel packaging configuration matches assembly requirements. Confirm the 'PWR' designation corresponds to the correct TSSOP package variant. Cross-reference the manufacturer datasheet for exact electrical tolerances and operating temperature ranges before integration.
Selection Notes
Select this component when automotive certification is mandatory for LED control applications. It is suitable for designs requiring individual channel current adjustment via I2C. Consider the 120 mA maximum sink capability against total load requirements. Evaluate the TSSOP footprint constraints against available PCB real estate.
Part Context
This part belongs to the Texas Instruments TLC59116 family of LED drivers. It shares core functionality with non-automotive variants but adds rigorous qualification for automotive environments. The family utilizes a common I2C interface architecture, allowing for consistent software implementation across different package options and temperature grades.
Replacement Considerations
The TLC59116IPWR serves as the commercial-grade equivalent without automotive certification. Verify if AEC-Q100 compliance is strictly required for the target application before substituting.
