The Texas Instruments TLC5955DCA is a versatile 48-channel LED driver designed for applications requiring precise brightness control. This linear driver supports 16-bit grayscale (GS) control, providing 65,536 steps for enhanced spectrum or conventional PWM dimming. It features analog/PWM mixed dimming capabilities, allowing for flexible control.
The device offers constant current output with a maximum current of 31.9 mA per channel and supports a wide input voltage range from 3V to 5.5V. Integrated features include dot correction (DC) control with 7 bits (128 steps) and global brightness control (BC) also with 7 bits (128 steps). The TLC5955DCA includes essential protection and diagnostic features such as LED open detection (LOD) and LED short detection (LSD).
Packaged in a 56-HTSSOP, the TLC5955DCA is designed for surface mount applications. Its operating temperature range is -40°C to 85°C, making it suitable for various environmental conditions. The driver's topology utilizes a shift register for control, and it supports a data transfer rate of 25 MHz.
This LED driver is ideal for signage applications and other display systems where precise and reliable LED illumination is critical. Its robust feature set and diagnostic capabilities contribute to system reliability and ease of design.
