TLC5948ADBQ Frequently Asked Questions (FAQs)

  • The TLC5948ADBQ can source up to 60mA per output, but it's recommended to limit it to 30mA to ensure reliable operation and prevent overheating.
  • The recommended sequence is: GSCLK low, SCLK low, XLAT low. Then, bring GSCLK high to latch the grayscale data, followed by SCLK high to shift in the data, and finally XLAT high to latch the data into the output registers.
  • The VPRG pin is used to set the internal voltage reference for the grayscale generator. It should be connected to a voltage source between 1.2V and 3.3V, with 2.5V being the recommended value. This sets the maximum brightness of the LEDs.
  • The TLC5948ADBQ has built-in thermal shutdown and overcurrent protection. If the device overheats or detects an overcurrent condition, it will shut down and the TSD pin will go low. To recover, simply power cycle the device or reset the TSD pin.
  • To minimize noise and ensure reliable operation, it's recommended to keep the GSCLK, SCLK, and XLAT signals short and away from the LED outputs. Also, use a solid ground plane and decouple the power supply with capacitors.
