MAX1232EWE

Supervisors Overview

The MAX1232EWE+ is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage input with threshold options of 4.5 V and 4.75 V. The device operates within a supply voltage range of 3.0 V to 5.5 V and consumes 200 uA of operating current. It features active high, active low, and open drain outputs, along with manual reset capability and an integrated watchdog timer. The reset delay time is specified at 1.2 s, with an accuracy of 10%. It is housed in a SOIC-Wide-16 package for surface mount installation.

Supervisors Feature Summary

• Integrates a watchdog timer for system fault detection
• Provides multiple output configurations including active high, active low, and open drain
• Supports manual reset functionality via dedicated input
• Monitors single voltage input with selectable threshold levels

Supervisors Applications

• Microprocessor power supply monitoring
• Embedded system supervision
• Industrial control unit reset management

Supervisors Procurement Notes

Verify the specific suffix (e.g., +T for tape and reel) against your manufacturing requirements. Confirm RoHS compliance status as indicated in official documentation. Check availability constraints as distribution may be limited. Ensure the SOIC-Wide-16 package matches your PCB footprint design specifications before ordering.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with watchdog functionality is required. Compare threshold voltages (4.5 V vs 4.75 V) against your system's nominal supply rail. Consider the 200 uA quiescent current for low-power designs. Verify that the SOIC-Wide-16 package fits your assembly constraints compared to standard SOIC widths.

Supervisors Part Context

The MAX1232 belongs to the Maxim Integrated supervisory circuit family designed for reliable system management. It complements other interface and power management ICs by providing essential reset and monitoring capabilities for digital logic circuits. This series supports various industrial and commercial applications requiring robust voltage supervision.
