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.
