Sales Briefcase
  • The STM70x supervisors are self-contained devices which provide microprocessor supervisory functions. A precision voltage reference and comparator monitors the VCC input for an out-of-tolerance condition. When an invalid VCC condition occurs, the reset output (RST) is forced low (or high in the case of RST).

    These devices also offer a watchdog timer (except for STM708T/S/R) as well as a power-fail comparator to provide the system with an early warning of impending power failure.
    The STM706P device is identical to the STM706R device, except its reset output is active high. These devices are available in a standard 8-pin SOIC package or a space-saving 8-pin TSSOP package.

    Key Features

    • Precision VCC monitor
      • T: 3.00 V ≤ VRST ≤ 3.15 V

    • RST andRSToutputs
    • 200 ms (typ.) trec
    • Watchdog timer - 1.6 s (typ.)
    • Manual reset input (MR)
    • Power-fail comparator (PFI/PFO)
    • Low supply current - 40 μA (typ.)
    • GuaranteedRST(RST) assertion down to VCC = 1.0 V
    • Operating temperature: –40 °C to 85 °C (industrial grade)
    • RoHS compliance
      • Lead-free components are compliant with the RoHS directive
