DS2413P+ datasheet by Maxim Integrated Products

DS2413P+ Frequently Asked Questions (FAQs)

• What is the maximum cable length for the 1-Wire bus?
  The maximum cable length for the 1-Wire bus is 300 meters (1000 feet), but it can be extended up to 750 meters (2500 feet) with the use of repeaters.
• How do I handle multiple devices on the same 1-Wire bus?
  To handle multiple devices on the same 1-Wire bus, each device must have a unique 64-bit ROM code. The master device can then use the ROM code to address and communicate with each device individually.
• What is the power consumption of the DS2413P+?
  The power consumption of the DS2413P+ is typically 1.5mA active and 1.5µA standby, but it can vary depending on the operating frequency and other factors.
• Can I use the DS2413P+ in a parasitic power mode?
  Yes, the DS2413P+ can be used in a parasitic power mode, where the device is powered from the 1-Wire bus. However, this mode is only suitable for low-power applications and requires careful design consideration.
• How do I ensure data integrity and security on the 1-Wire bus?
  To ensure data integrity and security on the 1-Wire bus, use a secure authentication protocol, such as SHA-1 or AES, and implement error-checking mechanisms, such as CRC or checksums, to detect data corruption or tampering.
