Instructions for Use

  1. Power Supply:

    • Connect VDD (pin 3) to the supply voltage (2.8V to 5.25V).
    • Connect GND (pin 1) to the ground.
  2. Data Line Connection:

    • Connect DQ (pin 2) to the data line of the 1-Wire network.
    • Ensure that the data line is pulled up to VDD with a resistor (typically 4.7kΩ).
  3. Initialization:

    • The DS2401Z must be initialized by the master device using the 1-Wire reset sequence.
    • The master sends a reset pulse on the data line, and the DS2401Z responds with a presence pulse.
  4. Read Serial Number:

    • After initialization, the master can read the unique 64-bit serial number by sending the appropriate 1-Wire command (0x33).
    • The DS2401Z will then transmit its serial number over the data line.
  5. Parasitic Powering:

    • The DS2401Z can operate in parasitic power mode, where it derives power from the data line.
    • In this mode, ensure that the data line has sufficient capacitance to maintain the required voltage during communication.
  6. Handling Precautions:

    • Handle the DS2401Z with care to avoid ESD damage.
    • Use proper ESD protection measures when handling and soldering the device.
  7. Storage and Operating Conditions:

    • Store the device in a dry, cool place within the specified storage temperature range.
    • Operate the device within the specified operating temperature range to ensure reliable performance.
