Overview
The STM1061N28WX6F 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 as long as the VCC input remains below the threshold plus hysteresis. The STM1061N28WX6F is guaranteed to output the correct logic state for VCC down to 0.7V and is immune to fast transients on VCC. It 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.
