The TLC5955DCAR from Texas Instruments is a versatile 48-channel, 16-bit PWM LED driver designed for applications requiring precise brightness control. This linear driver supports analog and PWM mixed dimming, offering 65,536 grayscale steps for enhanced spectrum or conventional PWM control.
Key electrical specifications include a per-channel LED current capability of up to 31.9 mA and an input voltage range of 3V to 5.5V. The device provides constant current accuracy with channel-to-channel variation typically within ±2%. It features integrated LED open and short detection for enhanced reliability.
Packaged in a 56-HTSSOP, the TLC5955DCAR is suitable for surface mount applications. Its operating temperature range is -40°C to 85°C, making it robust for various environmental conditions. The driver also includes features like auto display repeat and auto data refresh for simplified system integration.
This LED driver is well-suited for signage applications, offering precise control over individual LEDs or LED strings. Its serial interface simplifies communication with microcontrollers, while the dot correction and global brightness control features allow for fine-tuning of display uniformity and overall illumination.
