TLC59108IRGYR datasheet by Texas Instruments

TLC59108IRGYR Frequently Asked Questions (FAQs)

• What is the maximum current rating for each output channel?
  The TLC59108IRGYR has a maximum current rating of 30mA per output channel, with a total current limit of 120mA for all 8 channels combined.
• How do I ensure that the device is properly powered and initialized?
  To ensure proper power-up and initialization, connect VCC to a 3.3V or 5V power supply, and make sure the EN pin is tied high. Also, ensure that the SCL and SDA pins are properly connected to a microcontroller or other I2C master device.
• What is the maximum frequency for the I2C interface?
  The TLC59108IRGYR supports I2C frequencies up to 400 kHz, but it's recommended to operate at 100 kHz or lower for reliable communication.
• How do I handle thermal shutdown and overcurrent protection?
  The TLC59108IRGYR has built-in thermal shutdown and overcurrent protection. If the device overheats or detects an overcurrent condition, it will automatically shut down. To recover, simply power-cycle the device or reset the EN pin.
• Can I use the TLC59108IRGYR with a 5V microcontroller?
  Yes, the TLC59108IRGYR is 5V tolerant, so it can be used with 5V microcontrollers. However, ensure that the VCC pin is connected to a 3.3V or 5V power supply, and use level shifters if necessary to match the voltage levels.
