Power-On-Reset and Brown-Out-Reset with programmable detection thesholds

Key Benefits

  • A flexible offering enabling to implement only the relevant features
  • Ultra low power consumption of 13 μ
  • A in normal mode and 5 nA in low power mode enabling to optimize the overall consumption of the Always-On
  • Possibility to disable the BOR monitoring during low power mode in order to save power
  • High programmability: POR, PON and BOR thresholds are all programmable. BOR allows a dynamic programming to comply with the supply voltage of the power domain
  • Re-bootable PON when the supply is re-started or reset
