DS2502P-E64 datasheet by Maxim Integrated Products

DS2502P-E64 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the DS2502P-E64?
  The DS2502P-E64 can operate over a temperature range of -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 DS2502P-E64 over the 1-Wire bus?
  To ensure reliable communication, make sure to use a pull-up resistor on the 1-Wire bus, maintain a minimum bus capacitance of 750pF, and use a 1-Wire master device that complies with the 1-Wire protocol specification.
• Can I use the DS2502P-E64 in a multi-drop configuration?
  Yes, the DS2502P-E64 can be used in a multi-drop configuration, but each device must have a unique ROM ID and be addressed individually to avoid data corruption.
• How do I handle power-on reset and brown-out detection with the DS2502P-E64?
  The DS2502P-E64 has an internal power-on reset circuit that resets the device when the supply voltage falls below 2.5V. For brown-out detection, use an external voltage supervisor or a microcontroller with a built-in brown-out detection feature.
• What is the recommended layout and routing for the DS2502P-E64 to minimize EMI and noise?
  To minimize EMI and noise, use a ground plane, keep the 1-Wire bus traces short and away from noise sources, and use a common-mode choke or ferrite bead on the VCC line. Also, avoid running the 1-Wire bus traces near the edges of the PCB.
