DS1869-100 datasheet by Dallas Semiconductor

DS1869-100 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the DS1869-100?
  The DS1869-100 can operate from -40°C to +85°C, but it's recommended to operate within -20°C to +70°C for optimal performance.
• How do I ensure reliable communication with the DS1869-100 over the 1-Wire bus?
  To ensure reliable communication, make sure to use a pull-up resistor on the 1-Wire bus, keep the bus length short (<100m), and use a clock rate of 14.4 kHz or slower.
• Can I use the DS1869-100 with a 5V power supply?
  No, the DS1869-100 is designed to operate from 2.7V to 5.5V, but it's not recommended to use it with a 5V power supply as it may exceed the maximum rating. Use a 3.3V or lower power supply for optimal performance.
• How do I handle the power-on reset (POR) of the DS1869-100?
  The DS1869-100 has a built-in POR circuit that resets the device when the power supply voltage falls below 2.2V. To handle POR, ensure that your system design can tolerate the device's reset state during power-up and power-down cycles.
• What is the typical current consumption of the DS1869-100?
  The typical current consumption of the DS1869-100 is around 1.5mA during active operation, but it can be as low as 1µA in standby mode.
