TLC5940PWPG4

Overview

The TLC5940PWPG4 is a 16-channel constant-current sink LED driver manufactured by Texas Instruments. It features individually adjustable 4096-step grayscale PWM brightness control and an EEPROM-based dot correction mechanism for uniformity. The device utilizes a serial interface for data input and operates within a temperature range of -40°C to +85°C. It is housed in a 28-pin HTSSOP package. A single external resistor sets the maximum current value for all channels, supporting up to 120mA per output.

Feature Summary

Integrates 16-channel constant-current sinking with high-resolution grayscale control
Includes non-volatile EEPROM memory for storing dot correction data
Supports serial data input for efficient daisy-chaining and control

Applications

LED matrix displays requiring precise brightness uniformity
Backlighting systems for portable electronic devices
General-purpose LED indicator arrays

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific suffix 'G4' aligns with required lead-free and RoHS compliance standards. Check current availability status as this part may be subject to discontinuation or lifecycle changes. Ensure packaging specifications match the required surface-mount assembly processes.

Selection Notes

Select this component when high-resolution grayscale dimming and channel-to-channel uniformity are critical. The integrated dot correction reduces the need for external calibration hardware. Consider the 28-pin HTSSOP footprint for space-constrained designs. Evaluate the serial interface requirements against available microcontroller GPIO resources.

Part Context

This part belongs to the TLC5940 family of LED drivers from Texas Instruments. It is functionally similar to the TLC5940PWP but includes the 'G4' suffix indicating specific manufacturing or compliance variations. It serves as a dedicated solution for driving multiple LEDs with precise current control without complex external circuitry.
