MAXIM INTEGRATED / ANALOG DEVICES MAX704CSA Microprocessor Supervisory Circuit

The MAX704CSA+ is a low-cost microprocessor supervisory circuit with battery backup power switching, housed in an 8-pin NSOIC package. It simplifies power supply monitoring and battery control in microprocessor systems, enhancing system reliability and accuracy compared to discrete components. The device provides an active-low reset during power-up, power-down, and brownout conditions, and features battery backup switching for CMOS RAM, CMOS microprocessors, or other low-power logic circuitry. It includes a 1.25V threshold detector for power fail warning, low battery detection, or monitoring a supply voltage other than +5V. Typically used in computers, controllers, intelligent instruments, and critical microprocessor applications, it operates over a voltage range of 0V to 5.5V and a temperature range from 0°C to 70°C. Key features include a power-fail comparator, a 4.4V precision voltage monitor with a 200ms reset pulse, an active-low push-pull reset output, debounced TTL/CMOS manual reset input, and low quiescent currents of 200µA in normal operation and 50nA in battery backup mode. The reset assertion occurs when VCC drops to 1V.
