Overview
The STM1061N16WX6F 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 falls below the specified trip point threshold, the output (OUT) is forced low and remains asserted until the VCC rises above the threshold plus hysteresis. The STM1061 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 small device is ideal for portable applications and is available in space-saving SOT23-3 and SOT323-3 (SC70-3) packages.
