DS1990A-F5+ Frequently Asked Questions (FAQ)

  • The recommended power-up sequence is to apply VCC first, followed by VDD, and then the input signals. This ensures proper device operation and prevents latch-up.

  • To ensure reliable communication, ensure that the 1-Wire bus is properly terminated, use a pull-up resistor on the DQ pin, and implement a robust 1-Wire protocol with error checking and retries.

  • The maximum cable length supported by the DS1990A-F5+ is approximately 100 meters, but this can vary depending on the cable quality, noise environment, and 1-Wire bus configuration.

  • Implement a robust error handling mechanism that detects and recovers from errors, such as CRC errors, timeouts, and bus collisions. Use the device's built-in error detection mechanisms, such as the CRC and ROM ID checks.

  • Yes, the DS1990A-F5+ supports multi-drop 1-Wire bus configurations, but ensure that each device has a unique ROM ID and that the bus is properly terminated to prevent signal reflections.
