MAX6703LKA+ +BOM

Low-Voltage, SOT23, µP Supervisors with Power-Fail In/Out, Manual Reset, and Watchdog Timer

MAX6703LKA+ General Description

The MAX6701—MAX6708 microprocessor (µP) supervisory circuits reduce the complexity and components required to monitor power-supply functions in µP systems. These devices significantly improve system reliability and accuracy compared to separate ICs or discrete components.

Key Features

  • Small 8-Pin SOT23 Package
  • Precision Monitoring of +5.0V, +3.3V, +3.0V, +2.5V Supply Voltages
  • 140ms Reset Timeout Delay
  • Power-Fail Input with Independent Output; Monitor Inputs Down to 0.62V (MAX6704—MAX6708)
  • Dual Adjustable Reset Input for Triple-Voltage Monitoring (MAX6701(A)/MAX6702(A)/MAX6703(A))
  • 1.6s Watchdog Timeout Period (MAX6701(A)—MAX6707(A))
  • Independent Watchdog Output (MAX6701(A)/MAX6702(A)/MAX6703(A)/MAX6705(A)/MAX6706(A)/MAX6707(A))
  • Manual Reset Input
  • Four Reset Output Stage Options
    • Active Low Push-Pull (MAX6701(A), MAX6705(A))
