General Description  
____________________________Features  
♦ Precision Monitoring of +2.5V, +3V, +3.3V, and  
The MAX803/MAX809/MAX810 are microprocessor (µP)  
supervisory circuits used to monitor the power supplies  
in µP and digital systems. They provide excellent circuit  
reliability and low cost by eliminating external compo-  
nents and adjustments when used with +5V, +3.3V,  
+3.0V, or +2.5V powered circuits.  
+5V Power-Supply Voltages  
♦ Fully Specified Over Temperature  
♦ Available in Three Output Configurations  
Open-Drain RESET Output (MAX803)  
Push-Pull RESET Output (MAX809)  
Push-Pull RESET Output (MAX810)  
♦ 140ms min Power-On Reset Pulse Width  
♦ 12µA Supply Current  
♦ Guaranteed Reset Valid to VCC = +1V  
♦ Power Supply Transient Immunity  
♦ No External Components  
These circuits perform a single function: they assert a  
reset signal whenever the V  
supply voltage declines  
CC  
below a preset threshold, keeping it asserted for at  
least 140ms after V has risen above the reset thresh-  
CC  
old. Reset thresholds suitable for operation with a vari-  
ety of supply voltages are available.  
The MAX803 has an open-drain output stage, while the  
MAX809/MAX810 have push-pull outputs. The  
MAX803’s open-drain RESET output requires a pullup  
resistor that can be connected to a voltage higher than
