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 voltagesand supply tolerances are available to optimize theMAX6338 for specific applications. The selectionincludes input options for monitoring +5.0V, +3.3V,+3.0V, +2.5V, +1.8V, and -5.0V voltages. An additionalhigh-input impedance comparator option can be usedas an adjustable voltage monitor, general-purpose com-parator, or digital level translator. Each of the monitored voltages is available with tripthresholds 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 to +85 ) operating tempe ature range.
The MAX6338 consumes 25A (typ) supply current an operates with supply voltages from +2.5V to +5.5V. An internal undervoltage lockout circuit forces all four digital outputs low when VCC drops below the minimum operat- ing voltage. The four digital outputs all have weak inter- nal pull-ups to VCC , allowing wire-ORed connection.
Each input threshold voltage has an independent output. The MAX6338 is available in a 10-pin PAMAX package
