Description

The MAX6338 quad voltage monitor is capable of monitoring up to four supplies without any external components. 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 comparator, or digital level translator.

The MAX6338 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 temperature range.

The MAX6338 consumes 25A (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 VCC drops below the minimum operating voltage. The four digital outputs all have weak internal pull-ups to VCC, allowing wire-ORed connection. Each input threshold voltage has an independent output.

The MAX6338 is available in a 10-pin MAX package.
