CMOS power supply support circuit featuring a fixed +0.9V output. This voltage detector offers a 1% accuracy with a threshold voltage of 900mV, defined by undervoltage at 891mV and overvoltage at 909mV. Designed for surface mounting in a VSOP-4 package, it operates from 700mV to 7V supply voltage with a low quiescent current of 300nA. The device provides active high/active low reset functionality and supports a single monitored input.
