Frequently Asked Questions
How many LED output channels does the TLC5952DAPR support?
The TLC5952DAPR supports 24 constant-current output channels, each capable of driving LEDs at 26.2 mA or 35 mA. Multiple devices can be daisy-chained via the serial shift register interface to control large LED arrays with hundreds of channels, making it scalable for LED matrix displays and video wall applications.
What type of current output does the TLC5952DAPR provide?
The TLC5952DAPR provides constant-current outputs, ensuring that each LED receives a stable, consistent drive current regardless of variations in LED forward voltage. This guarantees uniform brightness across all 24 channels, which is essential for professional LED display panels, RGB lighting, and signage where color and brightness consistency is critical.
How is the TLC5952DAPR controlled by a microcontroller?
The TLC5952DAPR uses a serial data input interface (shift register) compatible with SPI communication, requiring only a few MCU pins regardless of the number of cascaded driver ICs. Data is shifted in serially and latched to control all 24 output channels simultaneously, enabling efficient control of large LED arrays with minimal GPIO usage.
What package does the TLC5952DAPR use?
The TLC5952DAPR is housed in a 32-pin HTSSOP (Heat-sink Thin Shrink Small Outline Package) with JESD-30 code R-PDSO-G32. This package provides an exposed thermal pad for improved heat dissipation, making it suitable for high-current LED driver applications where thermal management is important for long-term reliability.
