TLC5949PWP Frequently Asked Questions (FAQs)

  • The TLC5949PWP can sink up to 120mA per output, but it's recommended to limit the current to 60mA per output to ensure reliable operation and to prevent overheating.
  • The GSCLK signal should be high during data transfer, BLANK should be low during data transfer and high during blanking, and XLAT should be high during data transfer and low during blanking. A recommended sequence is: GSCLK high, XLAT high, data transfer, XLAT low, BLANK high, GSCLK low.
  • The IREF pin sets the maximum current for all outputs. It's recommended to set IREF to 1.24V for a maximum current of 60mA per output. You can use a resistor divider from VCC to set IREF to the desired voltage.
  • The TLC5949PWP has built-in thermal shutdown and overcurrent protection. If the device overheats or detects an overcurrent condition, it will shut down and the ERR pin will go low. You can use the ERR pin to detect errors and take corrective action, such as reducing the current or turning off the device.
  • It's recommended to keep the power and ground traces separate from the signal traces, and to use a solid ground plane to reduce noise and improve thermal dissipation. Keep the GSCLK and XLAT traces short and away from other signals to minimize noise and skew.
