STM1831中文资料Voltage detector with sense input and external delay capacitor数据手册ST规格书

描述 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.

特性 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
