Overview
The TLC59208FIPWR is an eight-channel LED driver IC from Texas Instruments, optimized for RGB/RGBA color mixing. It operates on a Fast-Mode Plus I2C bus interface with noise-filtered SCL and SDA inputs. Each output provides programmable brightness control via an 8-bit resolution. The device supports a supply voltage range of 3 V to 5.5 V and delivers up to 50 mA per channel. It functions within a temperature range of -40°C to +85°C and is housed in a 16-pin VQFN package.
Feature Summary
- Eight individually programmable LED outputs supporting 8-bit brightness control
- Fast-Mode Plus I2C bus interface with integrated noise filters on input lines
- Optimized architecture for red/green/blue/amber (RGBA) color mixing applications
Applications
- RGB and RGBA LED color mixing systems
- Backlighting for displays requiring precise color control
- General-purpose LED illumination where I2C control is required
Procurement Notes
Verify the specific suffix IPWR corresponds to the 16-pin VQFN package and tape-and-reel delivery format. Confirm RoHS compliance status and ensure the operating temperature range meets the application's thermal requirements. Cross-reference the datasheet revision to confirm pinout and electrical characteristics match the design specifications.
Selection Notes
Select this component when an I2C-controlled solution is needed for multi-color LED arrays. The 8-bit resolution offers sufficient granularity for most lighting effects. Ensure the host microcontroller supports Fast-Mode Plus I2C speeds. Consider the 50 mA output current limit against the total LED load requirements.
Part Context
This part belongs to the TLC59208F series of LED drivers. It shares functional similarities with other members like the TLC59208FIRGYR but differs in packaging and reel configuration. The series is designed for low-power, high-density LED control applications requiring minimal external components.
Replacement Considerations
The TLC59208FIRGYR is a confirmed substitute offering identical electrical functionality. Verify that the VQFN-16 package dimensions are compatible with the existing PCB footprint. No functional changes are expected between these variants.
