MAX703/MAX704  
Low-Cost Microprocessor Supervisory  
Circuits with Battery Backup  
General Description  
Features  
● Battery-Backup Power Switching  
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.  
● Precision Supply-Voltage Monitor  
• 4.65V (MAX703)  
• 4.40V (MAX704)  
● 200ms Reset Pulse Width  
● Debounced TTL/CMOS-Compatible Manual Reset  
Input  
The MAX703/MAX704 are available in 8-pin DIP and SO  
packages and provide four functions:  
● 200μA Quiescent Current  
● 50nA Quiescent Current in Battery-Backup Mode  
1) An active-low reset during power-up, power-down, and  
brownout conditions.  
● Voltage Monitor for Power-Fail or Low-Battery  
Warning  
● 8-Pin DIP and SO Packages  
● Guaranteed RESET Assertion to V  
2) Battery-backup switching for CMOS RAM, CMOS μPs,  
or other low-power logic circuitry.

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

The MAX703 and MAX704 differ only in their supplyvolt-  
age monitor levels. The MAX703 generates a reset when  
the supply drops below 4.65V, while the MAX704 gener-  
ates a reset below 4.40V.

Devices in PDIP and SO packages are available in both leaded  
and lead(Pb)-free packaging. Specify lead(Pb)-free by adding  
the “+” symbol at the end of the part number when ordering.
