Overview
The STM1061N34WX6F is a low power voltage detector produced by STMicroelectronics. This device is designed to monitor battery, power-supply, and regulated system voltages, providing essential voltage monitoring and reset timing for power-on resets. 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 this threshold, the output (OUT) is forced low and remains asserted until the VCC input rises above the threshold plus hysteresis. The STM1061 is particularly suited for portable applications due to its low power consumption and compact packaging in SOT23-3 and SOT323-3 (SC70-3) packages.
