CMOS power supply support circuit featuring a fixed, single-channel voltage detector for +3.4V monitoring. This surface mount component offers a 1% accuracy for its reset threshold, with a typical threshold voltage of 3.4V, ranging from 3.366V to 3.434V. Operating across a wide temperature range of -40°C to 125°C, it exhibits a low operating supply current of 550nA and a quiescent current of 500nA. The device supports active high/low reset outputs and is packaged in a 4-pin SOP for tape and reel distribution.
