MAX1232CWE+T

Supervisors Overview

The MAX1232CWE+T is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed to monitor a single input line for power supply integrity. It operates within a maximum supply voltage of 5.5 V and features configurable threshold voltages at 4.5 V and 4.75 V. The device provides active high, active low, or open drain output options and includes manual reset functionality alongside a watchdog timer. With a reset delay time of 1 second and a typical operating current of 200 uA, it ensures reliable system control in commercial temperature ranges from 0°C to +70°C.

Supervisors Feature Summary

• Integrates a watchdog timer for automated system recovery
• Supports multiple output configurations including active high, active low, and open drain
• Includes manual reset capability for user-initiated system control

Supervisors Applications

• Microprocessor monitoring systems
• Voltage supervisory circuits
• Power management IC applications

Supervisors Procurement Notes

Verify the specific suffix and package configuration against official datasheets before procurement. Confirm that the component meets RoHS requirements if applicable to your manufacturing standards. Check for any obsolescence notices or limited availability status directly with the manufacturer or authorized distributors. Ensure the selected variant matches the required thermal and electrical specifications for your design environment.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with integrated watchdog functionality is required. Consider the 1-second reset delay and available output types to match system timing needs. Verify that the 4.5 V and 4.75 V thresholds align with the monitored rail levels. Ensure the SOIC-Wide-16 package fits the PCB layout constraints and that the commercial temperature range suffices for the application.
