Overview
The TLC59116FIRHBR is a Texas Instruments LED lighting driver IC featuring 16 constant-current sink outputs. It utilizes a Fast-Mode Plus I2C bus interface for control, supporting up to 1 MHz data rates. The device operates on a supply voltage range of 3 V to 5.5 V and delivers an output current of 120 mA per channel. It incorporates an internal boost converter capable of generating up to 17 V to drive high-voltage LED strings. Packaged in a 32-VQFN (5x5 mm) with an exposed pad, it functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates an internal boost converter to enable driving of high-voltage LED loads from low supply voltages.
- Provides 16 individually addressable constant-current sink channels with programmable current levels.
- Supports Fast-Mode Plus I2C communication for efficient serial data transmission and control.
Applications
- LED backlighting systems for displays
- General LED illumination circuits
- Portable electronic device lighting
Procurement Notes
Verify the specific suffix 'F' against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure the ordering part number matches the exact variant required for your design, as suffixes may indicate differences in packaging or environmental ratings. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing standards.
Selection Notes
Select this component when a high channel count and I2C interface are required for LED control. The integrated boost capability simplifies designs involving series-connected LEDs. Consider the thermal performance of the VQFN package and the need for external components associated with the boost converter circuit during the schematic phase.
Part Context
This part belongs to the TLC59116 family of LED drivers from Texas Instruments. The family includes variants such as the TLC59116IPWR and automotive-grade versions like the TLC59116ITPWRQ1. These devices share core functionality but differ in package options, operating temperature ranges, and qualification standards suitable for different industrial and consumer applications.
Replacement Considerations
Direct substitutes include the TLC59116IPWR, which offers the same functional specifications in a TSSOP-28 package. Designers should verify pin-to-pin compatibility and thermal dissipation characteristics when switching between the VQFN and TSSOP packages.
