TLC5940PWPRG4 Description

Short technical summary and product information.

The TLC5940PWPRG4 from Texas Instruments is a versatile 16-channel LED driver designed for applications requiring precise brightness control. Each channel features individually adjustable 4096-step grayscale PWM control and a 64-step constant-current sink (dot correction) to manage brightness variations between LEDs.

 

This device operates with a supply voltage range of 3V to 5.5V and can drive up to 120mA per channel. It supports a maximum LED power supply voltage of 17V. The TLC5940PWPRG4 includes integrated EEPROM for storing dot correction data, accessible via a serial interface. It also features LED open detection (LOD) and thermal error flag (TEF) for error reporting.

 

Packaged in a 28-HTSSOP, the TLC5940PWPRG4 is suitable for surface mounting. Its applications include monocolor, multicolor, and full-color LED displays, signboards, and general high-current LED drive, particularly for backlighting solutions.
