Product overview

Description

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.

  • All 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
