TLC5940PWPR Description

Short technical summary and product information.

The TLC5940PWPR from Texas Instruments is a versatile 16-channel constant-current sink LED driver designed for applications requiring precise LED control. Each channel features individually adjustable 4096-step grayscale PWM brightness control and a 64-step constant-current sink (dot correction) to manage brightness variations between channels.

 

This device operates with a supply voltage range of 3V to 5.5V and can drive each channel with up to 120mA of current. It supports a maximum LED power supply voltage of 17V. The TLC5940PWPR includes integrated EEPROM for storing dot correction data, accessible via a serial interface. A single external resistor sets the maximum current for all channels.

 

Key features include LED open detection (LOD) and thermal error flag (TEF) for error reporting. The driver supports a 30 MHz data transfer rate and is housed in a 28-HTSSOP package suitable for surface mounting.

 

Applications for the TLC5940PWPR include monocolor, multicolor, and full-color LED displays, LED signboards, display backlighting, and general high-current LED drive.
