Low-Cost Microprocessor Supervisory  
Circuits with Battery Backup  
3/MAX704  
General Description  
Features  
The MAX703/MAX704 microprocessor (µP) supervisory  
circuits reduce the complexity and number of compo-  
nents required for power-supply monitoring and battery  
control functions in µP systems. These devices signifi-  
cantly improve system reliability and accuracy com-  
pared to that obtained with separate ICs or discrete  
components.

8-Pin DIP and SO Packages  
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.  
♦

Guaranteed RESET Assertion to V

3) A 1.25V threshold detector for power-fail warning,  
low-battery detection, or for monitoring a power  
supply other than +5V.  
Ordering Information  
4) 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.
