Application Scenarios & Design Considerations

MAX 1232 Microprocessor Monitor

Alternative Part Number

  • DS1232 --: Pin-compatible microprocessor supervisor with the same reset and watchdog functions, widely used as a direct substitute for the MAX1232.
  • ADM1232 --: Direct functional equivalent of the MAX1232 supervisor, offering the same reset threshold and watchdog timer in a compatible package.
  • ST1232 --: Alternative microprocessor supervisory circuit with comparable reset and watchdog features, suitable for replacing the MAX1232 in most designs.
  • STK1232 --: Comparable microprocessor supervisor IC providing reset generation and watchdog timing, usable as an alternative when the MAX1232 is unavailable.
