CMOS power supply support circuit featuring a fixed +3.1V threshold voltage with 1% accuracy. This voltage detector, designed for surface mount installation in a VSOP-4 package, provides a single channel of simple reset/power-on reset functionality. It operates across a wide temperature range from -40°C to 125°C, with a maximum power dissipation of 210mW. The device boasts a low operating supply current of 550nA, with quiescent and supply currents as low as 450nA and 1.4uA respectively. Reset output is available in active high or active low configurations.
