Overview
The STM1061N23WX6F is a low power voltage detector produced by STMicroelectronics. This device is designed to monitor battery, power-supply, and regulated system voltages. It features a precision voltage reference and comparator that compares the VCC input with a specified voltage threshold condition. When the VCC input falls below the specified trip point threshold, the output (OUT) is forced low and remains asserted until the VCC input rises above the threshold plus hysteresis. The STM1061N23WX6F is guaranteed to output the correct logic state even when VCC is as low as 0.7V and is immune to fast transients on VCC. This device is ideal for portable applications due to its low power consumption and compact packaging in SOT23-3 and SOT323-3 (SC70-3) packages.
