Power-Supply Monitor with Reset  
_______________General Description  
___________________________Features  
+5V, +3.3V, and +3V Versions  
The MAX709 provides a system reset during power-up,  
power-down, and brownout conditions. When VCC falls  
below the reset threshold, RESET goes low and holds  
the µP in reset for 140ms min after VCC rises above the  
threshold.  
No External Components  
Low Cost  
Precise Power-Down Reset Threshold  
140ms Min Power-On Reset Delay  
Immune to Short Negative VCC Transients  
8-Pin DIP, µMAX, and SO Packages  
The RESET output is guaranteed to be in the correct  
state with VCC down to 1V. The MAX709 provides  
excellent circuit reliability and low cost by eliminating  
external components and adjustments when used with  
+5V, +3.3V, or +3V powered systems. The MAX709 is  
available 8-pin DIP, µMAX, and SO packages.  
Low Supply Current: 35µA - MAX709R/S/T  
65µA - MAX709L/M
