TCA9803DGKR Frequently Asked Questions (FAQs)

  • The maximum current rating of the TCA9803DGKR is 100 mA per channel, with a total current limit of 200 mA for all channels combined.
  • The TCA9803DGKR can be configured for I2C or SMBus operation by connecting the SCL pin to a pull-up resistor and the SDA pin to a pull-up resistor or an open-drain output. The device will automatically detect the bus type based on the signal levels.
  • The minimum voltage required for the TCA9803DGKR to operate is 1.65 V, but it is recommended to operate the device at a minimum of 2.3 V for optimal performance.
  • The TCA9803DGKR can be reset by pulling the RESET pin low for at least 10 ns. This will reset the device to its default state.
  • The maximum clock frequency supported by the TCA9803DGKR is 400 kHz for I2C operation and 100 kHz for SMBus operation.
