Overview
The STM1061N17WX6F is a low power voltage detector produced by STMicroelectronics. This device is designed to monitor battery, power-supply, and regulated system voltages. It utilizes a precision voltage reference and comparator to compare 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 STM1061 is guaranteed to output the correct logic state even when VCC drops down to 0.7V and is immune to fast transients on VCC. This device is ideal for portable applications due to its low power consumption and is available in compact SOT23-3 and SOT323-3 (SC70-3) packages.
