MAX6381–MAX6390  
SC70/μDFN, Single/Dual Low-Voltage,  
Low-Power μP Reset Circuits  
General Description  
The MAX6381–MAX6390 microprocessor (μP) supervi-  
sory circuits monitor power-supply voltages from +1.8V  
to +5.0V while consuming only 3μA of supply current at  
Features  
● Factory-Set Reset Threshold Voltages Ranging from  
+1.58V to +4.63V in Approximately 100mV Increments  
● ±2.5% Reset Threshold Accuracy Over  
Temperature (-40°C to +125°C)  
+1.8V. Whenever V  
falls below the factory-set reset  
CC  
thresholds, the reset output asserts and remains asserted  
for a minimum reset timeout period after V rises above  
the reset threshold. Reset thresholds are available from  
+1.58V to +4.63V, in approximately 100mV increments.  
Seven minimum reset timeout delays ranging from 1ms  
to 1200ms are available.  
● Seven Reset Timeout Periods Available: 1ms, 20ms,  
140ms, 280ms, 560ms, 1120ms, 1200ms (min)  
CC  
● 3 Reset Output Options  
• Active-Low Push-Pull  
• Active-High Push-Pull  
• Active-Low Open-Drain  
TheMAX6381/MAX6384/MAX6387haveapush-pullactive-  
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

● Low Power Consumption of 6μA at +3.6V and 3μA at +1.8V  
MAX6390 offers a manual reset input with a longer V  
reset timeout period (1120ms or 1200ms) and a shorter  
manual reset timeout (140ms or 150ms).

MAX6326/MAX6327/MAX6328/MAX6346/MAX6347/  
MAX6348, and MAX6711/MAX6712/MAX6713  
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.

Note: Insert reset threshold suffix (see Reset Threshold table)  
after “XR”, “XS”, or “LT.” Insert reset timeout delay (see Reset  
Timeout Delay table) after “D” to complete the part number.  
Sample stock is generally held on standard versions only (see  
Standard Versions table). Standard versions have an order  
increment requirement of 2500 pieces. Nonstandard versions  
have an order increment requirement of 10,000 pieces.  
Contact factory for availability of nonstandard versions.
