TLC5923DAPR datasheet by Texas Instruments

TLC5923DAPR Frequently Asked Questions (FAQs)

• What is the maximum current that can be sourced or sunk by each output?
  The TLC5923DAPR 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 reset after power-up?
  To ensure proper reset, connect the RESET pin to a 10kΩ pull-up resistor to VCC, and add a 0.1μF capacitor between RESET and GND. This ensures a clean reset signal during power-up.
• What is the recommended clock frequency for the TLC5923DAPR?
  The recommended clock frequency for the TLC5923DAPR is between 100 kHz and 1 MHz. Operating the device outside this range may affect its performance and reliability.
• How do I handle the thermal management of the TLC5923DAPR?
  To manage thermal issues, ensure good airflow around the device, use a heat sink if necessary, and avoid operating the device near its maximum power rating for extended periods.
• What is the purpose of the EN pin, and how do I use it?
  The EN (Enable) pin is used to enable or disable the device. When EN is high, the device is enabled, and when EN is low, the device is disabled. Use the EN pin to control the device's power consumption and output state.
