TLC5923DAPRG4 datasheet by Texas Instruments

TLC5923DAPRG4 Frequently Asked Questions (FAQs)

• What is the maximum current that can be sourced or sunk by each output?
  The TLC5923 can source up to 25mA and sink up to 50mA per output, but it's recommended to limit the current to 10mA per output for reliable operation.
• How do I ensure that the TLC5923 is properly powered and initialized?
  Make sure to connect VCC to a stable 3.3V or 5V power supply, and connect VEE to GND. Also, ensure that the reset pin (RST) is pulled high during power-up to ensure proper initialization.
• What is the maximum clock frequency that can be used with the TLC5923?
  The TLC5923 can operate with clock frequencies up to 25MHz, but it's recommended to use a clock frequency of 10MHz or less for reliable operation.
• How do I handle the thermal shutdown feature of the TLC5923?
  The TLC5923 has a built-in thermal shutdown feature that activates when the junction temperature exceeds 150°C. To handle this, ensure good thermal design and heat dissipation, and consider using a thermal monitoring circuit to detect and respond to thermal shutdown events.
• Can I use the TLC5923 with a 3.3V microcontroller?
  Yes, the TLC5923 is compatible with 3.3V microcontrollers. However, ensure that the microcontroller's output voltage is within the TLC5923's input voltage range (Vih = 0.7VCC, Vil = 0.3VCC).
