The MAX6391/MAX6392 microprocessor (µP) supervisory circuits provide sequenced logic reset outputs for multiponent or dual-voltage systems.

Each device can monitor two supply voltages and time-sequence two reset outputs to control the order in which system ponents are turned on and off.

The MAX6391/MAX6392 increase system reliability and reduce circuit plexity and cost pared to separate ICs or discrete ponents.

o Preset VCC Reset Threshold Voltages from 1.58V to 4.63V (master supply) o Customer-Adjustable RESET IN2 to Monitor Voltages Down to 625mV (secondary supply) o Fixed (140ms min) RESET1 Timeout o Fixed (140ms min) or Customer-Adjustable RESET2 Timeout Period o Guaranteed Reset Valid to VCC = 1V o Active-Low Open-Drain Outputs or PushPull/Open-Drain Combination o Internal Open-Drain Pullup Resistors (for external VOH voltage connections) o Manual Reset Input (MAX6392 only) o Immune to Short Negat.
