3-Pin, Ultra-Low-Power SC70/SOT  
µP Reset Circuits  
General Description  
Features  
The MAX6326/MAX6327/MAX6328/MAX6346/MAX6347/  
MAX6348 microprocessor (µP) supervisory circuits moni-  
tor the power supplies in µP and digital systems. These  
devices provide excellent circuit reliability and low cost  
by eliminating external components and adjustments  
when used with 2.5V, 3V, 3.3V, and 5V powered circuits.  
ꢀ Ultra-Low 1µA (max) Supply Current  
(MAX6326/MAX6327/MAX6328)  
ꢀ Precision Monitoring of 2.5V, 3V, 3.3V, and 5V  
Power-Supply Voltages  
ꢀ Reset Thresholds Available from 2.2V to 4.63V  
ꢀ Fully Specified Over Temperature  
ꢀ 100ms (min) Power-On Reset Pulse Width  
ꢀ Low Cost  
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  
100ms after V has risen above the reset threshold.  
CC  
ꢀ Available in Three Versions: Push-Pull RESET,  
Push-Pull RESET, and Open-Drain RESET  
The only difference between the devices is their output.  
The MAX6326/MAX6346 (push-pull) and MAX6328/  
MAX6348 (open-drain) have an active-low reset output.  
The MAX6327/MAX6347 have an active-high push-pull  
reset output. All of these parts are guaranteed to be in  
ꢀ Power-Supply Transient Immunity  
ꢀ No External Components  
ꢀ 3-Pin SC70/SOT23 Packages  
the correct state for V  
down to 1V. The reset compara-  
CC  
tor is designed to ignore fast transients on V . Reset  
ꢀ Pin Compatible with MAX803/MAX809/MAX810  
CC  
thresholds are factory-trimmable between 2.2V and  
4.63V, in approximately 100mV increments. Twenty-one  
standard versions are available. Contact the factory for  
availability of nonstandard versions.

†The MAX6326/MAX6327/MAX6328/MAX6346/MAX6347/  
MAX6348 are available in factory-set V reset thresholds from  
CC  
2.2V to 4.63V, in approximately 0.1V increments. Choose the  
desired reset-threshold suffix from Table 1 and insert it in the  
blank spaces following “R.” There are 21 standard versions with  
a required order increment of 2500 pieces. Sample stock is gen-  
erally held on the standard versions only (see the Selector  
Guide). Required order increment is 10,000 pieces for nonstan-  
dard versions (Table 2). Contact factory for availability. All  
devices available in tape-and-reel only.
