TLC59108FIPWR

Overview

The TLC59108FIPWR is an eight-channel LED driver IC manufactured by Texas Instruments, housed in a 20-pin TSSOP package. It operates on a supply voltage range of 3 V to 5.5 V and supports Fast-Mode Plus I2C bus communication at frequencies up to 1 MHz. The device provides constant current outputs with a maximum channel current of 120 mA and can drive loads up to 17 V. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates eight independent constant current sinks for precise LED brightness control
• Supports Fast-Mode Plus I2C bus interface for efficient digital control
• Features internal linear regulation for stable output current performance

Applications

• LED backlighting systems
• Indicator lighting circuits
• General-purpose LED illumination

Procurement Notes

Verify the specific suffix FIPWR corresponds to the 20-TSSOP package variant. Confirm the Fast-Mode Plus I2C capability matches system requirements. Ensure thermal management aligns with the specified operating temperature range. Cross-reference datasheet electrical characteristics against design constraints.

Selection Notes

Select this component when eight individually controllable LED channels are required with I2C interface compatibility. Consider the 120 mA output capacity and 17 V load voltage limits. Evaluate the TSSOP-20 footprint for PCB layout constraints. Verify power supply stability within the 3 V to 5.5 V input range.

Part Context

This part belongs to the TLC59108 family of LED drivers from Texas Instruments. It shares core functionality with variants like TLC59108IPWR and TLC59108IRGYR, differing primarily in packaging type. The family targets applications requiring multi-channel LED control via standard serial interfaces.

Replacement Considerations

TLC59108IPWR offers identical electrical specifications in a standard TSSOP-20 package. TLC59108F_15 represents another variant within the same functional family. Verify pinout compatibility before substitution.
