TLC5940PWP Description

Short technical summary and product information.

The TLC5940PWP 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 includes integrated EEPROM for storing dot correction data, accessible via a serial interface. The TLC5940PWP also incorporates error detection features, including LED Open Detection (LOD) and Thermal Error Flag (TEF).

 

Packaged in a 28-HTSSOP, the TLC5940PWP is suitable for surface mounting. Its applications include monocolor, multicolor, and full-color LED displays, signboards, and general high-current LED drive requirements, particularly for display backlighting.

 

Key electrical specifications include a 30 MHz data transfer rate and CMOS level I/O. A single external resistor sets the maximum current for all 16 channels, simplifying design and component selection.
