Dual-Voltage µP Supervisory Circuits  
with Sequenced Reset Outputs  
General Description  
Features  
The MAX6391/MAX6392 microprocessor (µP) supervisory  
circuits provide sequenced logic reset outputs for multi-  
component or dual-voltage systems. Each device can  
monitor two supply voltages and time-sequence two reset  
outputs to control the order in which system components  
are turned on and off. The MAX6391/MAX6392 increase  
system reliability and reduce circuit complexity and cost  
compared to separate ICs or discrete components.  
o Preset V

Reset Threshold Voltages from 1.58V  
to 4.63V (master supply)

o Fixed (140ms min) or Customer-Adjustable

The MAX6391/MAX6392 monitor V

reset supply. Both RESET1 and RESET2 are asserted  
whenever V drops below the selected factory-fixed

exceed their thresholds. RESET2 is always deasserted  
after RESET1 during system power-up and is always  
asserted before RESET1 during power-down.  
The MAX6391 includes two internal pullup resistors for  
RESET1 and RESET2 (the open-drain outputs can be  
externally connected to the desired pullup voltages).  
The MAX6392 includes an active-low manual reset  
input (MR) that asserts both RESET1 (push-pull) and  
RESET2 (open drain).

SOT23 packages and are specified over the -40°C to  
+85°C extended temperature range.  
*Insert the desired suffix (see Selector Guide) into the blanks to  
complete the part number. The MAX6391/MAX6392 require a  
2.5k minimum order increment and are available in tape-and-  
reel only. Samples are typically available for standard versions  
(see Selector Guide for standard versions). Contact factory for
