DS12885SN+ Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VBAT. This ensures that the internal voltage regulators are properly initialized.
  • To ensure accurate timekeeping during power failures, use a battery-backed clock (BBR) or a supercapacitor to maintain the RTC's operation. The DS12885SN+ has a built-in battery switch-over circuit to automatically switch to the backup power source during power failures.
  • The maximum allowed voltage on the VBAT pin is 3.6V. Exceeding this voltage can damage the internal battery switch-over circuit.
  • Yes, the DS12885SN+ can operate in a 3.3V system. However, the VCC pin should be connected to a 3.3V power supply, and the VBAT pin should be connected to a 3.0V battery or a supercapacitor.
  • To reset the DS12885SN+ to its default settings, apply a low signal (less than 0.8V) to the RST pin for at least 100ns. This will reset the device to its power-on default state.
