TLC5940PWPR

Overview

The TLC5940PWPR is a 16-channel constant-current LED driver IC manufactured by Texas Instruments, housed in a 28-pin HTSSOP package. It operates on a supply voltage range of 3 V to 5.5 V and delivers up to 120 mA per channel with an output voltage capability of 17 V. The device supports a 30 MHz data input rate and features internal EEPROM for factory-set dot correction and grayscale PWM control. It functions within a temperature range of -40°C to +85°C.

Feature Summary

Integrates 16-bit grayscale PWM control for precise brightness adjustment across all channels.
Includes built-in dot correction via internal EEPROM to compensate for individual LED brightness variations.
Provides open-LED detection capabilities to identify circuit faults during operation.
Utilizes a serial interface for data input, reducing the number of required control pins.

Applications

LED backlighting systems
Dot matrix displays
General LED lighting drivers

Procurement Notes

Verify that the specific part number matches the required HTSSOP-28 package configuration. Confirm that the operating environment stays within the specified -40°C to +85°C temperature limits. Ensure the design accounts for the 120 mA maximum current per channel to prevent thermal issues. Check RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when independent 16-bit grayscale control and hardware-based dot correction are required. It is suitable for designs needing high channel density without external multiplexing. Consider the 120 mA sink capability for direct LED driving. Evaluate the serial interface requirements against available microcontroller resources.

Part Context

This device belongs to the TLC5940 series of LED drivers from Texas Instruments. It is designed for applications requiring high-resolution grayscale and uniform brightness across multiple LEDs. The series is commonly used in display and lighting solutions where consistent color and intensity are critical.
