TLC5925IPWR datasheet by Texas Instruments

TLC5925IPWR Frequently Asked Questions (FAQs)

• What is the maximum current that can be sourced or sunk by each output?
  The TLC5925IPWR can source up to 25mA and sink up to 50mA per output.
• How do I ensure that the device is properly powered and configured?
  Make sure to connect VCC to a 3.3V or 5V power supply, and GND to ground. Also, configure the device using the serial interface (SCL and SDA pins) according to the datasheet.
• What is the purpose of the REXT resistor, and how do I choose its value?
  The REXT resistor sets the current limit for the output stages. Choose a value between 1kΩ and 5kΩ to set the current limit between 10mA and 50mA.
• How do I handle the thermal considerations for this device?
  Ensure good thermal conductivity by providing a heat sink or a thermal pad on the PCB. Also, keep the device away from heat sources and ensure good airflow.
• What is the maximum frequency of the serial clock (SCL) pin?
  The maximum frequency of the SCL pin is 400 kHz.
