TLC5946PWR Description

Short technical summary and product information.

The TLC5946PWR from Texas Instruments is a versatile 16-channel LED driver IC. It features 12-bit grayscale PWM control for precise dimming and 6-bit dot correction for enhanced color accuracy, supporting up to 40mA constant current sink output per channel.

 

This device operates with a supply voltage ranging from 3.0V to 5.5V, with LED power supply voltage capability up to 17V. It includes features such as error flags, fault detection, and LED open/short detection for robust operation. The channel-to-channel accuracy is typically ±1%.

 

Designed for surface mounting, the TLC5946PWR comes in a 28-TSSOP package. Its operating temperature range is -40°C to 85°C, making it suitable for various environmental conditions. Applications include monochrome, multicolor, and full-color LED displays, LED signboards, and display backlighting.

 

The driver utilizes a shift register topology and supports a data transfer rate of up to 30MHz, with a 33MHz grayscale PWM clock. It also incorporates noise reduction features like 4-channel grouped delay.
