TLC5947RHBRG4 Frequently Asked Questions (FAQs)

  • The maximum frequency of the clock input is 30 MHz, but it's recommended to keep it below 20 MHz for reliable operation.
  • The recommended sequence is: GSCLK low, BLANK high, XLAT low, then GSCLK high. This ensures proper data loading and blanking.
  • The OUTGRP pin is used to group multiple TLC5947 devices together, allowing them to be controlled as a single unit. It's used for dot correction and grayscale data loading.
  • The TLC5947 has a built-in thermal shutdown feature that disables the output drivers when the junction temperature exceeds 150°C. To handle this, monitor the THERMAL_METAL flag and take corrective action, such as reducing the output current or shutting down the device.
  • Keep the GSCLK, BLANK, and XLAT signals short and away from noisy signals. Use a solid ground plane and decouple the power supply with capacitors. Keep the output traces short and matched to minimize electromagnetic interference (EMI).
