TLC59284DBQ

Overview

The TLC59284DBQR is a Texas Instruments LED lighting driver IC featuring 16 constant-current outputs in a 24-SSOP package. It operates on a 3V to 5.5V supply with a maximum output current of 45mA per channel and an output voltage of 10V. The device supports a 35MHz data transfer rate and functions within a -40°C to +85°C temperature range.

Feature Summary

• Provides 16-channel constant-current regulation for uniform LED brightness
• Integrates internal switching delay control for precise timing management
• Supports high-speed serial data input for efficient daisy-chain connectivity

Applications

• LED signage displays
• Backlight illumination systems
• General LED lighting arrays

Procurement Notes

Verify the specific suffix (e.g., DBQR vs DBQ) matches the required packaging format, as reel or tube variations exist. Confirm RoHS compliance status and moisture sensitivity level requirements against the specific datasheet revision. Ensure the ordering part number aligns exactly with the requested tape-and-reel quantity or tube configuration to avoid assembly line discrepancies.

Selection Notes

Select this component when 16 independent channels are required with fixed current settings. Compare against the TLC5928 series if adjustable current or different topologies like boost are needed. Consider the SSOP package constraints for PCB space and thermal dissipation capabilities relative to the total power consumption of the connected LED array.

Part Context

This part belongs to the TLC59284 family of constant-current LED drivers from Texas Instruments. It shares architectural similarities with the TLC5928 but offers higher output current capability and integrated switching delay features. The family targets applications requiring reliable, multi-channel LED control without complex external circuitry.

Replacement Considerations

Public confirmed substitute part numbers include TLC59284DBQR.A.
