TLC5947RHBT 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.
  • To ensure proper initialization, the TLC5947RHBT requires a power-on reset (POR) pulse on the RST pin. The POR pulse should be at least 1.5 ms wide and have a voltage level between 0.8 V and 2.5 V.
  • The GSCLK pin is the grayscale clock input. It is used to update the grayscale data in the TLC5947RHBT. The GSCLK frequency should be at least 10 times the frequency of the SCLK pin.
  • The TLC5947RHBT has a built-in thermal shutdown feature that activates when the junction temperature exceeds 150°C. To handle this, ensure proper heat sinking and thermal design. If thermal shutdown occurs, the device will recover automatically when the temperature drops below 130°C.
  • To minimize noise and ensure proper operation, it's recommended to follow a star topology for the power and ground connections. Keep the analog and digital signal traces separate, and use a solid ground plane to reduce noise and electromagnetic interference (EMI).
