MAX703/MAX704 Low-Cost Microprocessor Supervisory Circuits with Battery Backup General Description The MAX703/MAX704 microprocessor (μP) supervisory circuits reduce the complexity and number of components required for power-supply monitoring and battery control functions in μP systems.
These devices significantly improve system reliability and accuracy compared to that obtained with separate ICs or discrete components.
The MAX703/MAX704 are available in 8-pin DIP and SO packages and provide four functions: 1) An active-low reset during power-up, power-down, and brownout conditions.
2) Battery-backup switching for CMOS RAM, CMOS μPs, or other low-power logic circuitry.
3) A 1.
