The STM1831 is a voltage detector with very low current consumption. It monitors a voltage on a separate input pin (VSEN), which is fully functional even if the monitored voltage goes down to 0 V. In addition, the delay of the output can be adjusted by an external capacitor.

Key features
  • Voltage monitored on separate sense input VSEN
  • Factory-trimmed voltage thresholds in 100 mV increments from 1.6 V to 5.7 V
  • ±2% voltage threshold accuracy
  • Operating voltage 1.6 V to 6.0 V
  • Open drain output
  • Low supply current of 0.8 μA (typ.)
  • Time delay programmable by external capacitor
  • Power supply transient immunity
  • Available in SOT23-5 package
  • Operating temperature –40 to 85 °C
