General Description
The MAX6339 is a precision quad voltage monitor with
microprocessor (μP) supervisory reset timing. The device
can monitor up to four system supply voltages without
any external components and asserts a single reset if any
supply voltage drops below its preset threshold. The
device significantly reduces system size and component
count while improving reliability compared to separate
ICs or discrete components.
A variety of factory-trimmed threshold voltages are avail-
able to accommodate different supply voltages and toler-
ances with minimal external component requirements.
The selection includes internally fixed options for monitor-
ing +5.0V, +3.3V, +3.0V, +2.5V, +1.8V, and -5.0V sup-
plies with -5% and/or -10% tolerances. The device is also
available with one or two user-adjustable threshold
options if non-standard thresholds are desired (use exter-
nal resistor-divider network).
The quad monitor provides a single active-low reset out-
put that is asserted when any monitored input is below its
associated threshold. The output is open drain with a
weak internal pull-up (10μA) to IN2. Reset remains low for
a reset timeout period (140ms min) after all voltages are
above the selected thresholds. The output is valid as long
as either the IN1 or IN2 input voltage remains >1V.
The MAX6339 is available in a small 6-pin SOT23 pack-
age and operates over the extended (-40°C to +85°C)
temperature range.
