Quad Voltage Monitor in µMAX Package
General Description
The MAX6338 quad voltage monitor is capable of moni-
toring up to four supplies without any external compo-
nents. A variety of factory-trimmed threshold voltages
and supply tolerances are available to optimize the
MAX6338 for specific applications. The selection
includes input options for monitoring +5.0V, +3.3V,
+3.0V, +2.5V, +1.8V, and -5.0V voltages. An additional
high-input impedance comparator option can be used
as an adjustable voltage monitor, general-purpose com-
parator, or digital level translator.
Each of the monitored voltages is available with trip
thresholds to support power-supply tolerances of either
5% or 10% below the nominal voltage. An internal
bandgap reference ensures accurate trip thresholds
across the extended (-40°C to +85°C) operating temper-
ature range.
The MAX6338 consumes 25µA (typ) supply current and
operates with supply voltages from +2.5V to +5.5V. An
internal undervoltage lockout circuit forces all four digital
outputs low when V
CC
drops below the minimum operat-
ing voltage. The four digital outputs all have weak inter-
nal pull-ups to V
CC
, allowing wire-ORed connection.
Each input threshold voltage has an independent output.
The MAX6338 is available in a 10-pin µMAX
®
package.
