Low-Power, SC70/SOT µP Reset Circuits with  
Capacitor-Adjustable Reset Timeout Delay  
General Description  
Features  
The MAX6340/MAX6421–MAX6426 low-power micro-  
processor supervisor circuits monitor system voltages  
from 1.6V to 5V. These devices perform a single function:  
o Monitor System Voltages from 1.6V to 5V  
o Capacitor-Adjustable Reset Timeout Period  
o Low Quiescent Current (1.6µA typ)  
o Three RESET Output Options  
they assert a reset signal whenever the V  
supply volt-  
CC  
age falls below its reset threshold. The reset output  
remains asserted for the reset timeout period after V  
CC  
rises above the reset threshold. The reset timeout is exter-  
nally set by a capacitor to provide more flexibility.  
Push-Pull RESET  
Push-Pull RESET  
Open-Drain RESET  
The MAX6421/MAX6424 have an active-low, push-  
pull reset output. The MAX6422 has an active-high,  
push-pull reset output and the MAX6340/MAX6423/  
MAX6425/MAX6426 have an active-low, open-drain  
reset output. The MAX6421/MAX6422/MAX6423 are  
offered in 4-pin SC70 or SOT143 packages. The  
MAX6340/MAX6424/MAX6425/MAX6426 are available  
in 5-pin SOT23-5 packages.  
o Guaranteed Reset Valid to V  
= 1V

o Immune to Short V  
Transients

o MAX6340 Pin Compatible with LP3470  
o MAX6424/MAX6425 Pin Compatible with  
NCP300–NCP303, MC33464/MC33465,  
S807/S808/S809, and RN5VD

Pin Configurations  
Note: The MAX6340/MAX6421–MAX6426 are available with fac-  
tory-trimmed reset thresholds from 1.575V to 5.0V in approxi-  
mately 0.1V increments. Insert the desired nominal reset  
threshold suffix (from Table 1) into the blanks. There are 50 stan-  
dard versions with a required order increment of 2500 pieces.  
Sample stock is generally held on standard versions only (see  
Standard Versions Table). Required order increment is 10,000  
pieces for nonstandard versions. Contact factory for availability.  
All devices are available in tape-and-reel only.
