ADM1232:  Microprocessor Supervisory Circuit

Product Description

The ADM1232 is a superior, pin-compatible upgrade for the MAX1232 and the DS1232LP and DS1232. The Analog Devices ADM1232 is a microprocessor monitoring circuit that can monitor:

  • Microprocessor Supply Voltage
  • Whether a Microprocessor has locked-up
  • An External Interrupt

    • The ADM1232 is available in four different packages:

  • The ADM1232ARM in an 8-lead microSOIC (RM-8).
  • The ADM1232AN in an 8-lead PDIP (N-8).
  • The ADM1232ARW in a 16-lead wide SOIC (R-16).
  • The ADM1232ARN is an 8-lead narrow SOIC (R-8).

    • Features

    • Superior Upgrade for MAX1232 and Dallas DS1232
    • Adjustable Precision Voltage Monitor with +4.5 V and +4.75 V Options
    • Low Power Consumption (500 µA max)
    • Adjustable STROBE Monitor with 150 ms,600 ms or 1.2 sec Options
    • No External Components
