TLC5946PWPR Frequently Asked Questions (FAQs)

  • The maximum frequency of the clock input is 25 MHz. However, it's recommended to use a clock frequency between 10 kHz to 10 MHz for optimal performance.
  • The grayscale signal should be updated during the blanking period (BLANK = 1). The blanking signal should be asserted (BLANK = 1) before updating the grayscale signal, and de-asserted (BLANK = 0) after the update is complete.
  • The OUTMOD0 and OUTMOD1 pins are used to configure the output mode of the TLC5946. OUTMOD0 sets the output mode for channels 0-15, and OUTMOD1 sets the output mode for channels 16-31. The output modes can be set to either open-drain or totem-pole.
  • The TLC5946 has a built-in thermal shutdown protection that activates when the junction temperature exceeds 150°C. When this occurs, the device will shut down and the outputs will be turned off. To handle this, ensure proper heat sinking and thermal management, and consider implementing a thermal monitoring and shutdown circuit.
  • To minimize noise and ensure proper operation, it's recommended to follow a star-topology layout, with the TLC5946 at the center. Keep the clock and data lines short and away from noisy signals, and use a solid ground plane to reduce electromagnetic interference.
