DS1267BE-010+ Frequently Asked Questions (FAQs)

  • A good PCB layout practice is to keep the analog and digital grounds separate, use a solid ground plane, and place the device close to the battery or power source. Additionally, use a low-ESR capacitor (e.g., 10uF) between VCC and GND to filter out noise.
  • To ensure accuracy, calibrate the device using the CAL pin, and use the internal temperature sensor's built-in calibration data. For extreme temperatures, consider using an external temperature sensor with a higher accuracy rating.
  • The maximum allowed voltage on the VCC pin is 5.5V. Exceeding this voltage can cause permanent damage to the device, so ensure that the power supply is regulated and within the recommended range of 2.7V to 5.5V.
  • Connect the BAT pin to a voltage divider circuit that monitors the battery voltage. When the battery voltage falls below a certain threshold (e.g., 2.5V), the BAT pin will go low, indicating a low-battery condition.
  • The RST pin is an active-low reset input that resets the device when pulled low. To reset the device, pull the RST pin low for at least 100ns, then release it to allow the device to restart.
