MAX6412–MAX6420  
Low-Power, Single/Dual-Voltage µP Reset Circuits  
with Capacitor-Adjustable Reset Timeout Delay  
General Description  
Features  
The MAX6412–MAX6420 low-power microprocessor  
supervisor circuits monitor system voltages from 1.6V to  
5V. These devices are designed to assert a reset signal  
o Monitor System Voltages from 1.6V to 5V  
o Capacitor-Adjustable Reset Timeout Period  
o Manual Reset Input  
whenever the V supply voltage or RESET IN falls below  
CC  
(MAX6412/MAX6413/MAX6414)  
its reset threshold or the manual reset input is asserted.  
The reset output remains asserted for the reset timeout  
o Adjustable Reset Input Option (MAX6415–MAX6420)  
period after V  
and RESET IN rise above the reset  
CC  
o Dual-Voltage Monitoring  
threshold and the manual reset input is deasserted. The  
reset timeout is externally set by a capacitor to provide  
more flexibility.  
(MAX6418/MAX6419/MAX6420)  
o Low Quiescent Current (1.7µA, typ)  
The MAX6412/MAX6413/MAX6414 feature fixed thresholds  
from 1.575V to 5V in approximately 100mV increments and  
a manual reset input. The MAX6415/MAX6416/MAX6417  
are offered with an adjustable reset input that can monitor  
voltages down to 1.26V and the MAX6418/MAX6419/  
MAX6420 are offered with one fixed input and one  
adjustable input to monitor dual-voltage systems.  
o 3 RESET Output Options  
Push-Pull RESET  
Push-Pull RESET  
Open-Drain RESET  
o Guaranteed Reset Valid to V  
= 1V  
CC  
o Power-Supply Transient Immunity  
o Small SOT23-5 Packages  
The MAX6412/MAX6415/MAX6418 have an active-low,  
push-pull reset output. The MAX6413/MAX6416/  
MAX6419 have an active-high, push-pull reset output  
and the MAX6414/MAX6417/MAX6420 have an active-  
low, open-drain reset output. All of these devices are  
offered in a SOT23-5 package and are fully specified  
from -40°C to +125°C.

Table 1) into the blanks following the letters UK. There are 33  
standard 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.
