TLC59282DBQ

Overview

The TLC59282DBQ is a Texas Instruments linear LED driver IC featuring sixteen constant-current sink channels in a 24-SSOP package. It operates on a 3V to 5.5V supply voltage with outputs supporting up to 17V. The device delivers 45mA per channel and supports serial data input at frequencies up to 35MHz. Designed for surface-mount installation, it functions within an ambient temperature range of -40°C to +85°C.

Feature Summary

Four-channel grouped delay capability minimizes simultaneous switching noise by staggering LED output transitions.
Serial interface topology simplifies control connections for display applications.
Linear regulation provides stable constant current output for LED channels.

Applications

LED video displays
Message boards
Amusement illumination systems
LED indicator arrays

Procurement Notes

Verify the specific suffix 'DBQ' corresponds to the tube packaging variant rather than the 'R' tape-and-reel version. Confirm the 45mA channel current rating matches design requirements, distinguishing it from the 35mA TLC5928DBQ. Ensure the 24-SSOP footprint aligns with PCB layout specifications before ordering.

Selection Notes

Select this component when reduced electromagnetic interference from simultaneous switching is critical. The four-channel grouping feature facilitates low-cost two-layer PCB routing. Compare against the standard TLC5928 if lower current consumption is acceptable, or consider the VQFN package option for different thermal constraints.

Part Context

This part belongs to the TLC5928 family of serial-controlled LED drivers. It shares the core architecture with variants like the TLC5928DBQ but offers higher channel current capacity. The device integrates internal switches and shift register logic for efficient control of large LED matrices.
