TLC5940PWPG4 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 TLC5940PWPG4 has a built-in thermal shutdown feature that turns off the device when it overheats. To handle this, you can monitor the TSD (Thermal Shutdown) pin, which goes low when the device is in thermal shutdown. You can also implement a thermal management system to reduce the device's temperature.
  • The recommended value for the VPRG pin capacitor is 10 nF to 100 nF. This capacitor helps to filter the voltage reference and reduce noise.
  • To configure the grayscale clock mode, you need to set the GCK (Grayscale Clock) pin high and the SCK (Serial Clock) pin low. Then, you can send the grayscale data on the SDI (Serial Data Input) pin, and the device will generate the corresponding PWM signals.
  • The XLAT pin is used to latch the grayscale data into the device's internal registers. When XLAT is high, the device updates the PWM outputs with the new grayscale data. When XLAT is low, the device holds the current PWM outputs.
