Overview
The TLC5926IDWR is a Texas Instruments LED lighting driver IC featuring 16 constant-current sink outputs in a 24-pin SOIC package. It operates on a 3 V to 5.5 V supply with a maximum output current of 120 mA per channel and supports a 30 MHz serial interface. The device utilizes a boost topology, reaching up to 17 V output voltage, and functions within a -40°C to +125°C temperature range.
Feature Summary
- Provides 16 individually addressable constant-current sink channels for precise LED control
- Integrates thermal shutdown protection to safeguard against overheating conditions
- Supports high-speed serial data input via standard SPI-compatible interfaces
Applications
- General LED illumination systems requiring uniform current distribution
- Portable electronic devices utilizing low-voltage power supplies
- Industrial indicator panels and status display modules
Procurement Notes
Verify the specific suffix IDWR confirms the SOIC-24 package and tape-and-reel shipping configuration. Ensure compatibility with 3V to 5.5V logic levels and confirm thermal management requirements for the target operating environment. Cross-reference datasheet revision dates to ensure feature consistency.
Selection Notes
Select this component when 16-channel constant-current sinking is required without internal PWM dimming capabilities. It suits designs needing simple serial control and robust fault protection. Consider alternative packages like DBQR or IPWPRG4 if space constraints or specific termination styles differ from the standard SOIC form factor.
Part Context
Part of the TLC5926 family, which includes variants such as TLC5926IDBQR and TLC5926IPWPRG4. These share identical electrical specifications but differ in physical packaging, including QSOP-24 and HTSSOP-24 options. The series focuses on reliable constant-current regulation for general-purpose LED applications.
Replacement Considerations
Direct substitutes include TLC5926IDBQR (QSOP-24) and TLC5926IPWPRG4 (HTSSOP-24). Verify pinout compatibility and package dimensions before substitution. Other TLC5926 variants maintain functional equivalence but require mechanical assessment.
