This surface mount supervisory circuit, packaged in SOT-23-5, monitors a single voltage with a reset threshold of 3.075V, featuring both undervoltage (3V) and overvoltage (3.15V) detection. It provides an active low, totem-pole output and includes a watchdog timer with a 140ms reset timeout. Operating from 1V to 5.5V, this RoHS compliant component draws a maximum supply current of 12uA and functions across a temperature range of -40°C to 85°C.
