TLC5973DR Frequently Asked Questions (FAQs)

  • The maximum current rating for each output channel is 15mA. However, it's recommended to limit the current to 10mA per channel for reliable operation.
  • To ensure proper initialization, apply a reset pulse to the RST pin, then send a 'mode set' command (0x01) to set the device to the desired mode. After that, send a 'brightness' command (0x02) to set the initial brightness level.
  • The OUTEN pin is an output enable pin that allows you to disable all output channels simultaneously. To use it, connect OUTEN to a digital output of your microcontroller and set it high to enable the outputs or low to disable them.
  • The TLC5973DR uses a 12-bit grayscale format, where 0x000 represents minimum brightness and 0xFFF represents maximum brightness. You can use a 12-bit unsigned integer to represent the grayscale value for each channel.
  • The recommended clock frequency for the SCL pin is between 100 kHz and 400 kHz. However, the device can operate up to 1 MHz, but with reduced reliability.
