The TLC5946PWPR from Texas Instruments is a 16-channel, 12-bit Pulse Width Modulation (PWM) LED driver designed for applications such as monochrome, multicolor, and full-color LED displays, LED signboards, and display backlighting.
This device features 6-bit dot correction for precise LED brightness control, providing 64 steps of adjustment. It supports a constant current sink output capability of up to 40mA per channel. The grayscale PWM control offers 12-bit resolution, translating to 4096 steps for fine-tuning LED intensity.
Key electrical characteristics include a typical data transfer rate of 30 MHz and a channel-to-channel accuracy of ±1%. The LED power supply voltage can be up to 17V, while the device's own VCC operates from 3.0V to 5.5V. It includes features like LED open detection, LED short to ground detection, and thermal error flags for enhanced reliability.
The TLC5946PWPR is available in a 28-HTSSOP package, suitable for surface mounting. Its operating temperature range is -40°C to +85°C, making it suitable for a wide range of environmental conditions.
