TLC5926QPWPRQ1 datasheet by Texas Instruments

TLC5926QPWPRQ1 Frequently Asked Questions (FAQs)

• What is the maximum current that can be sourced or sunk by each output?
  The TLC5926QPWPRQ1 can source up to 25mA and sink up to 50mA per output, making it suitable for driving LEDs, relays, and other loads.
• How do I ensure that the device is properly powered and configured?
  Make sure to connect VCC to a stable 3.3V or 5V power supply, and tie the OE (Output Enable) pin high to enable the outputs. Also, ensure that the RST (Reset) pin is tied high or connected to a pull-up resistor to prevent accidental resets.
• What is the purpose of the R-C filter on the clock input?
  The R-C filter on the clock input is used to filter out noise and ensure a clean clock signal. It is recommended to use a 1kΩ resistor and a 10nF capacitor for the filter.
• How do I handle the thermal considerations for this device?
  The TLC5926QPWPRQ1 has a thermal pad on the bottom of the package, which should be connected to a thermal plane or a heat sink to dissipate heat. Ensure good thermal conductivity and avoid thermal gradients to prevent overheating.
• What is the recommended layout and routing for the device?
  Keep the device's power and ground pins close to the power supply, and use short, wide traces for the output lines. Avoid routing signals under the device, and keep the clock and data lines separate to minimize noise coupling.
