The Texas Instruments TLC5944PWP is a versatile 16-channel, 12-bit Pulse Width Modulation (PWM) LED driver designed for various display applications. It provides a constant current sink output of up to 60mA per channel, enabling precise control over LED brightness. The device features 12-bit grayscale control for 4096 steps and 6-bit dot correction for 64 steps, allowing for detailed illumination adjustments.
Key electrical characteristics include a data transfer rate of 30MHz and a grayscale control clock of 33MHz, facilitating high-speed operation. The operating voltage range for VCC is 3.0V to 5.5V, with an LED power-supply voltage capability of up to 15V. Channel-to-channel current accuracy is typically ±1%, and device-to-device accuracy is ±3%.
Designed for surface mounting, the TLC5944PWP comes in a 28-HTSSOP package. It includes features such as LED open detection, thermal shutdown, and pre-charge FETs to prevent ghosting phenomena in multiplexed LED systems. The operating temperature range is -40°C to 85°C, making it suitable for demanding environments.
This LED driver is ideal for applications like monochrome, multicolor, and full-color LED displays using multiplexing systems, as well as LED signboards.
