TLC5971RGET Frequently Asked Questions (FAQs)

  • The TLC5971RGET has a maximum current rating of 15mA per channel, but it's recommended to limit the current to 10mA per channel for reliable operation.
  • Proper thermal management is crucial for the TLC5971RGET. Ensure good airflow around the device, use a heat sink if necessary, and avoid blocking the thermal pad on the bottom of the package.
  • Keep the power traces short and wide, use a solid ground plane, and avoid routing signals under the device. Also, keep the LED current sense resistors close to the device and use a Kelvin connection to minimize noise.
  • The internal voltage regulator output (VREG) should be decoupled with a 1uF capacitor to GND. This output can be used to power other devices, but ensure the total current drawn does not exceed 50mA.
  • The EN (enable) pin is an active-low input that enables or disables the device. Tie EN to GND to enable the device, or to VCC to disable it. Use EN to turn off the device when not in use to reduce power consumption.
