DS1390U-18+ Frequently Asked Questions (FAQs)

  • 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 potential latch-up conditions.
  • To ensure accurate temperature measurement, it's essential to follow proper PCB layout and thermal design guidelines. Keep the device away from heat sources, use a thermally conductive material for the PCB, and ensure good airflow around the device.
  • The maximum cable length for the 1-Wire interface is approximately 100 meters (328 feet). However, this can vary depending on the cable quality, noise environment, and system design. It's recommended to use a shielded cable and follow proper termination techniques to minimize signal degradation.
  • Yes, the DS1390U-18+ supports multi-drop 1-Wire bus configurations. However, it's essential to follow the 1-Wire bus protocol and ensure that each device on the bus has a unique address. Additionally, the bus master should be able to handle the increased capacitance and signal degradation associated with multiple devices on the bus.
  • The parasitic power supply in the DS1390U-18+ can be handled by adding a 1 kΩ to 10 kΩ resistor between the VDD pin and the power supply. This helps to limit the current drawn from the parasitic power supply and ensures proper device operation.
