TLC5941PWP

Overview

The TLC5941PWP is a Texas Instruments LED display driver featuring 16 constant-current sink channels in a 28-PowerTSSOP package. It operates on a 3V to 5.5V supply with an internal shift register topology. Each channel delivers up to 80mA output current, supporting a maximum output voltage of 17V. The device includes dot correction and fault detection capabilities. It functions within a temperature range of -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Integrates 16-channel linear constant-current sinks for precise LED control
• Includes built-in dot correction and error flag mechanisms for uniformity
• Features open/short detection for enhanced system reliability

Applications

• LED backlighting systems
• Signage displays

Procurement Notes

Verify the specific suffix PWP corresponds to the 28-PowerTSSOP (4.40mm width) surface-mount package configuration. Confirm that the component meets RoHS3 compliance requirements for your assembly process. Ensure the operating environment stays within the specified -40°C to +85°C ambient temperature limits during design validation.

Selection Notes

Select this component when designing circuits requiring 16 individually addressable LED channels with integrated grayscale control. It is suitable for applications needing high brightness consistency through dot correction features. Consider the thermal performance of the PowerTSSOP package if multiple channels operate at maximum current simultaneously.

Part Context

This part belongs to the TLC5941 series of LED drivers from Texas Instruments. It serves as a specialized solution for managing multi-channel LED arrays without external current-setting resistors. The device simplifies PCB layout by integrating the shift register and constant-current regulation into a single compact package.
