Description

General part information

MAX703 Series

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:An active-low reset during power-up, power-down, and brownout conditions.Battery-backup switching for CMOS RAM, CMOS µPs, or other low-power logic circuitry.A 1.25V threshold detector for power-fail warning, low-battery detection, or for monitoring a power supply other than +5V.An active-low manual reset input.The MAX703 and MAX704 differ only in their supply-voltage monitor levels. The MAX703 generates a reset when the supply drops below 4.65V, while the MAX704 generates a reset below 4.40V.ApplicationsComputersControllersCritical µP Power MonitoringIntelligent Instruments
