DS2411P+ datasheet by Maxim Integrated Products

DS2411P+ 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's recommended to keep the cable length as short as possible to minimize signal degradation and noise.
• How do I handle multiple DS2411P+ devices on the same 1-Wire bus?
  Each DS2411P+ device has a unique 64-bit ROM code that can be used to identify and address individual devices on the same bus. You can use the ROM code to select which device to communicate with.
• What is the power consumption of the DS2411P+?
  The DS2411P+ has a typical active current of 1.5mA and a standby current of 1μA. The power consumption depends on the operating mode and the frequency of the 1-Wire bus.
• How do I implement a reliable 1-Wire bus reset?
  A reliable 1-Wire bus reset can be implemented by pulling the DQ pin low for at least 480μs, followed by a 480μs delay before re-initializing the bus. This ensures that all devices on the bus are properly reset.
• What is the maximum data transfer rate of the DS2411P+?
  The DS2411P+ supports a maximum data transfer rate of 15.3kbps, which is the standard data rate for the 1-Wire bus.
