The STM6xxx supervisors are self-contained devices which provide microprocessor supervisory functions. A precision voltage reference and comparator monitors the VCCinput for an out-of-tolerance condition. When an invalid VCCcondition occurs, the reset output (RST) is forced low (or high in the case of RST). These devices also offer a watchdog timer (except for STM6322/6825) and/or a push-button (MR) reset input.


These devices are available in a standard 5-pin SOT23 package.

Key features
  • Precision VCC monitoring of 5, 3.3, 3, or 2.5 V power supplies
  • RST outputs (active low, push-pull or open drain)
  • RST outputs (active high, push-pull)
  • Reset pulse width of 1.4 ms, 200 ms and 240 ms (typ.)
  • Watchdog timeout period of 1.6 s (typ.)
  • Manual reset input (MR)
  • Low supply current - 3 μA (typ.)
  • GuaranteedRST(RST) assertion down to VCC= 1.0
    V
  • Operating temperature: –40 to +85 °C (industrial grade)
  • RoHS complianceLead-free components are compliant with the RoHS directive
