Overview
The STM1061N38WX6F 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 monitors the VCC input and compares it with a specified voltage threshold condition. When VCC falls below the specified trip point threshold, the output (OUT) is forced low and remains asserted as long as VCC remains below VTH– + hysteresis (VHYST). The STM1061N38WX6F is ideal for portable applications due to its low power consumption and is available in space-saving SOT23-3 and SOT323-3 (SC70-3) packages.
