TLC5958RTQR

Overview

The TLC5958RTQR is a Texas Instruments LED driver featuring 48 constant-current sink channels with 16-bit ES-PWM resolution. It supports multiplexing ratios from 1 to 32 and includes 48k-bit display data memory. The device integrates pre-charge FETs, LED open/short detection, and error flags. Operating voltage ranges from 3V to 5.5V, with output voltage up to 10V and channel current at 25mA. It functions within a temperature range of -40°C to +85°C in a 56-VFQFN package.

Feature Summary

Integrates 48k-bit display data memory for efficient signal handling
Provides individual channel brightness control via 16-bit ES-PWM
Includes built-in fault detection for LED open and short circuits

Applications

Signage displays
Multiplexed LED matrix systems
High-density LED lighting arrays

Procurement Notes

Verify the specific ordering suffix RTQR against the official Texas Instruments datasheet to ensure correct packaging and tape specifications. Confirm that the component meets RoHS compliance requirements for your region. Check moisture sensitivity level (MSL) ratings to determine storage and reflow soldering constraints. Ensure the QFN-56 footprint matches your PCB layout design before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring high-resolution grayscale control for large LED matrices. The integrated memory reduces external microcontroller load by storing display data internally. Consider the 48-channel count and multiplexing capabilities to optimize board space. Verify thermal management needs due to the dense channel configuration in the small QFN package.

Part Context

This part belongs to the TLC5958 family of LED drivers designed for complex display applications. It serves as a constant-current sink solution for multiplexed LED systems. The device simplifies interface requirements by handling PWM generation and data storage internally. It is commonly used in professional signage and industrial lighting where precise color and brightness control are critical.
