TLC5948ADBQR Frequently Asked Questions (FAQs)

  • The maximum frequency of the clock input is 50 MHz, but it's recommended to use a clock frequency between 10 kHz to 20 MHz for optimal performance.
  • The recommended sequence is: GSCLK low, SCLK low, XLAT high, then GSCLK high, SCLK high, and finally XLAT low. This ensures proper data loading and latch operation.
  • 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 protection feature that limits the device junction temperature to 150°C. If the device overheats, it will shut down and restart when the temperature drops below 120°C. Ensure proper heat sinking and thermal design to prevent overheating.
  • Keep the GSCLK, SCLK, and XLAT signal traces short and away from noisy power supply lines. Use a solid ground plane and decouple the power supply with capacitors. Avoid routing critical signals under the device or near the heat sink.
