TLC5940QPWPREP Frequently Asked Questions (FAQs)

  • The maximum frequency of the clock input is 30 MHz, but it's recommended to use a clock frequency between 10 kHz to 20 MHz for optimal performance.
  • To ensure proper initialization, the TLC5940QPWPREP requires a power-on reset (POR) pulse on the RST pin, followed by a clock pulse on the CLKIN pin. This sequence should be repeated after each power-up or reset.
  • The GSCLK pin is used to synchronize the grayscale clock with an external clock source. Connect the GSCLK pin to an external clock source, and ensure that the frequency of the external clock is within the recommended range of 10 kHz to 20 MHz.
  • The TLC5940QPWPREP has a built-in thermal shutdown feature that activates when the junction temperature exceeds 150°C. To handle thermal shutdown, monitor the TSD pin, which goes low when the device enters thermal shutdown. When the device cools down, the TSD pin will go high, and normal operation will resume.
  • To minimize noise and ensure reliable operation, follow these layout and routing guidelines: keep the power supply lines (VCC and GND) separate from the signal lines, use a solid ground plane, and keep the clock and data lines as short as possible.
