CMOS voltage detector with a fixed +3.8V threshold, offering 1% accuracy. This power supply support circuit features a single monitored input and a totem-pole output. Operating from 0.7V to 7V, it consumes a low 550nA quiescent current. The component is housed in a surface-mount SOP package, suitable for tape and reel packaging, and operates within a temperature range of -40°C to 125°C. It provides active high/low reset functionality and is lead-free and RoHS compliant.
