TLC5951RHAR Frequently Asked Questions (FAQs)

  • The maximum clock frequency for the TLC5951RHAR is 25 MHz.
  • To ensure proper initialization, the TLC5951RHAR requires a reset pulse on the RST pin, followed by a clock pulse on the CLKIN pin to latch the data.
  • The GSCLK pin is used to clock the grayscale data into the TLC5951RHAR. It is typically connected to the same clock source as the CLKIN pin.
  • The TLC5951RHAR has an internal current source, and the LED current is set by the IREF pin. The IREF pin sets the maximum current for all LEDs, and the current for each LED is set by the grayscale data.
  • The TLC5951RHAR can drive up to 48 LEDs, divided into 16 channels with 3 LEDs per channel.
