SC70/µDFN, Single/Dual Low-Voltage,  
Low-Power µP Reset Circuits  
81–MAX6390  
General Description  
Features  
o Factory-Set Reset Threshold Voltages Ranging  
from +1.58V to +4.63V in Approximately 100mV  
Increments  
The MAX6381–MAX6390 microprocessor (µP) supervisory  
circuits monitor power-supply voltages from +1.8V to  
+5.0V while consuming only 3µA of supply current at  
+1.8V. Whenever V  
falls below the factory-set reset

thresholds, the reset output asserts and remains assert-  
ed for a minimum reset timeout period after V rises  
Temperatꢁre (-40°C to +1±5°C)

o SeOen Reset Timeoꢁt Periods AOailable: 1ms,  
±0ms, 140ms, ±80ms, 560ms, 11±0ms,  
1±00ms (min)  
above the reset threshold. Reset thresholds are available  
from +1.58V to +4.63V, in approximately 100mV incre-  
ments. Seven minimum reset timeout delays ranging  
from 1ms to 1200ms are available.

The MAX6381/MAX6384/MAX6387 have a push-pull  
active-low reset output. The MAX6382/MAX6385/  
MAX6388 have a push-pull active-high reset output,  
and the MAX6383/MAX6386/MAX6389/MAX6390  
have an open-drain active-low reset output. The

MAX6384/MAX6385/MAX6386 also feature  
a
debounced manual reset input (with internal pullup  
resistor). The MAX6387/MAX6388/MAX6389 have an  
auxiliary input for monitoring a second voltage. The

o Low Power Consꢁmption of 6µA at +3.6V  
and 3µA at +1.8V  
The MAX6381/MAX6382/MAX6383 are available in  
3-pin SC70 and 6-pin µDFN packages and the  
MAX6384–MAX6390 are available in 4-pin SC70 and  
6-pin µDFN packages.
