TLC5948APWP Frequently Asked Questions (FAQs)

  • The maximum frequency of the clock input is 50 MHz. However, it's recommended to operate the device at a frequency below 30 MHz to ensure reliable operation.
  • The recommended sequence is: GSCLK low, BLANK high, XLAT low, then GSCLK high. This sequence ensures that the device is properly reset and configured before data is loaded.
  • The OUTGRP pin is used to group multiple TLC5948 devices together to increase the total number of output channels. It allows the devices to be connected in a daisy-chain configuration.
  • The TLC5948 has a built-in thermal shutdown feature that activates when the device temperature exceeds 150°C. To handle this, ensure proper heat sinking, reduce the current output, or implement a thermal monitoring and shutdown circuit.
  • To minimize noise and ensure reliable operation, it's recommended to keep the GSCLK, BLANK, and XLAT signals short and away from the output channels. Use a solid ground plane and decouple the power supply with capacitors.
