TLC5916ID datasheet by Texas Instruments

TLC5916ID Frequently Asked Questions (FAQs)

• What is the maximum current that can be sourced or sunk by each output?
  The TLC5916ID can source up to 30mA and sink up to 64mA per output, making it suitable for driving LEDs, relays, and other loads.
• How do I ensure that the TLC5916ID is properly powered and configured?
  Make sure to connect VCC to a 3.3V or 5V power supply, and tie the RST pin to VCC through a 1kΩ resistor to ensure proper reset. Also, configure the device using the I2C interface by sending the correct commands and data to the device.
• What is the purpose of the OE (Output Enable) pin?
  The OE pin is an active-low input that enables or disables all outputs simultaneously. When OE is low, all outputs are enabled, and when OE is high, all outputs are disabled.
• How do I handle thermal protection and overcurrent protection?
  The TLC5916ID has built-in thermal protection that limits the junction temperature to 150°C. For overcurrent protection, use external resistors to limit the current to each output, and consider adding external protection devices such as fuses or PTCs.
• What is the maximum frequency of the I2C clock signal?
  The TLC5916ID supports I2C clock frequencies up to 400 kHz, making it suitable for high-speed applications.
