The TLC5944PWPR from Texas Instruments is a 16-channel, 12-bit Pulse Width Modulation (PWM) LED driver. It provides a constant current sink output of up to 60mA per channel, with 6-bit dot correction for precise grayscale control.
This device features a 12-bit grayscale resolution (4096 steps) and 6-bit dot correction (64 steps), enabling detailed LED dimming and color adjustment. It operates with a supply voltage (VCC) ranging from 3.0V to 5.5V and can drive LEDs with a power-supply voltage up to 15V. The data transfer rate is 30MHz, and the grayscale control clock runs at 33MHz.
Key features include internal pre-charge FETs to prevent ghosting in multiplexed systems, continuous LED open detection (LOD), thermal shutdown (TSD) with pre-thermal warning (PTW), and readable error information. Noise reduction is achieved through 4-channel grouped delay to prevent inrush current.
The TLC5944PWPR is housed in a 28-HTSSOP package and is designed for surface mount applications. Its operating temperature range is -40°C to 85°C, making it suitable for various LED display applications.
