STM6321 - 5-pin supervisor

General Description

The STM6xxx 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.

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. ).
  • Guaranteed RST (RST) assertion down to VCC = 1.0 V.
  • Operating temperature:.
  • 40 to +85 °C (industrial.
