Maxim Integrated MAX703
The MAX703 and MAX704 differ only in their supplyvoltage monitor levels. The MAX703 generates a reset when the supply drops below 4.65V, while the MAX704 generates a reset below 4.40V.| Part No. | MAX703 |

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 1.25V threshold detector for power-fail warning, low-battery detection, or for monitoring a power supply other than +5V. 4) An active-low manual reset input.APPLICATIONS
