TLC59461PWP 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, SCLK low, XLAT high, then GSCLK high, SCLK high, and finally XLAT low. This ensures proper data loading and latch operation.
  • The VPRG pin is used to set the internal voltage reference for the grayscale PWM generator. Connect it to a voltage source between 1.2V and 3.3V to set the reference voltage, or leave it open for a default internal reference of 1.2V.
  • The TLC59461PWP has a built-in thermal shutdown feature that disables the device when it overheats. To handle this, monitor the TSD pin, which goes low when the device is in thermal shutdown. When this occurs, stop sending data and wait for the device to cool down before resuming operation.
  • Keep the GSCLK, SCLK, and XLAT signals short and away from noisy signals. Use a solid ground plane and decouple the power supply with a 0.1uF capacitor. Also, keep the OUTx pins away from the power supply and ground pins to minimize noise coupling.
