TLC5940QRHBREP Description

Short technical summary and product information.

The Texas Instruments TLC5940QRHBREP is an enhanced product, 16-channel LED driver designed for applications requiring precise control over LED illumination. It offers both Dot Correction and Grayscale PWM Control, with 12-bit (4096 steps) resolution for grayscale and 6-bit (64 steps) for dot correction, storable in integrated EEPROM.

 

This linear LED driver supports a constant-current sink capability ranging from 0 mA to 120 mA, depending on the supply voltage and temperature conditions. It operates with a supply voltage (VCC) between 3V and 5.5V, and can drive LED power supplies up to 17V. Key features include PWM control, a serial data interface with a 30-MHz data transfer rate, and CMOS level I/O.

 

Error detection is provided through LED Open Detection (LOD) and Thermal Error Flag (TEF). The TLC5940QRHBREP is suitable for monocolor, multicolor, and full-color LED displays, LED signboards, and display backlighting. Its enhanced product rating supports defense, aerospace, and medical applications, with a controlled baseline, single assembly/test site, and single fabrication site.

 

The device is available in a 32-VQFN (5x5 mm) package and a 28-HTSSOP package. It is designed for surface mount applications and operates within an extended temperature range of -40°C to 125°C.
