MAX6391 - Dual Voltage uP Supervisory Circuits

Download the MAX6391 datasheet PDF. This datasheet also covers the MAX6392 variant, as both devices belong to the same dual voltage up supervisory circuits family and are provided as variant models within a single manufacturer datasheet.

General Description

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

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

Key Features

  • 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.

www.DataSheet4U.com 19-2210; Rev 1; 10/02 Dual-Voltage µP Supervisory Circuits with Sequenced Reset Outputs General Description The MAX6391/MAX6392 microprocessor (µP) supervisory circuits provide sequenced logic reset outputs for multicomponent or dual-voltage systems. Each device can monitor two supply voltages and time-sequence two reset outputs to control the order in which system components are turned on and off. The MAX6391/MAX6392 increase system reliability and reduce circuit complexity and cost compared to separate ICs or discrete components. The MAX6391/MAX6392 monitor V CC as the master reset supply. Both RESET1 and RESET2 are asserted whenever VCC drops below the selected factory-fixed reset threshold voltage.
