CMOS voltage detector with a fixed +4.2V threshold, offering 1% accuracy. This power supply support circuit features active high/low reset, a 4.158V undervoltage threshold, and a 4.242V overvoltage threshold. Operating from -300mV to 7V, it consumes a maximum supply current of 1.58µA and a typical quiescent current of 500nA. Packaged in a 4-pin SOP for surface mounting, it operates between -40°C and 125°C with a maximum power dissipation of 400mW.
