DS1982-F5+ datasheet by Maxim Integrated Products

DS1982-F5+ Frequently Asked Questions (FAQs)

• What is the maximum number of devices that can be connected to a single 1-Wire bus?
  The DS1982-F5+ can support up to 256 devices on a single 1-Wire bus, but the actual number of devices that can be connected depends on the specific application and the bus capacitance.
• How do I ensure reliable communication over the 1-Wire bus?
  To ensure reliable communication, it's essential to follow the 1-Wire bus layout guidelines, use a pull-up resistor, and implement error checking and correction mechanisms in the firmware.
• What is the maximum cable length for the 1-Wire bus?
  The maximum cable length for the 1-Wire bus depends on the cable capacitance and the bus speed. As a general guideline, the cable length should not exceed 100 meters at a bus speed of 14.4 kbps.
• How do I handle conflicts between multiple devices on the 1-Wire bus?
  To handle conflicts, use a unique 64-bit ROM ID for each device, and implement a collision detection and resolution mechanism in the firmware to ensure that only one device responds to a command at a time.
• What is the power consumption of the DS1982-F5+?
  The power consumption of the DS1982-F5+ depends on the operating mode. In active mode, the typical current consumption is 1.5 mA, and in standby mode, it's typically 1 μA.
