Key Features

  • Primary supply (VCC1) monitor. Fixed (factory-programmed) reset thresholds: 4.63 V to 1.58 V.
  • Secondary supply (VCC2) monitor (STM6717/18/19/20/77/78).
  • Fixed (factory-programmed) reset thresholds: 3.08 V to 0.79 V.
  • Tertiary supply monitor (using externally adjustable RSTIN): 0.626 V internal reference.
  • RST outputs (push-pull or open drain); state guaranteed if VCC1 or VCC2 ≥ 0.8 V.
  • Reset delay time (trec) on power-up: 13.2 ms, 210 ms, 900 ms (typ).
  • Manual rese.
