MAX1232EWE+

Supervisors Overview

The MAX1232EWE+ is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage input with fixed thresholds of 4.37V and 4.62V. The device features an open-drain or open-collector output capable of active-high or active-low reset signals, with a minimum reset timeout of 250ms. It operates within a supply voltage range of 3.0V to 5.5V and supports temperatures from -40°C to +85°C. Packaged in a 16-SSOP format, it provides essential power management supervision for embedded systems.

Supervisors Feature Summary

• Monitors a single voltage rail against fixed threshold levels
• Provides configurable active-high or active-low reset output
• Ensures system stability with a minimum 250ms reset timeout

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix and package variant during procurement, as the MAX1232 family includes multiple packaging options such as DIP and SOIC. Confirm that the fixed threshold requirements align with your design needs, as this part lacks programmable voltage settings. Check current availability status, as distribution channels may report limited stock or discontinuation for certain variants. Ensure compatibility with your board's thermal and electrical specifications before finalizing orders.

Supervisors Selection Notes

Select this component when a simple, fixed-threshold supervisor is sufficient for single-rail monitoring. It is suitable for applications requiring basic power-on reset functionality without complex sequencing. Consider alternative parts if adjustable thresholds, manual reset inputs, or watchdog timers are required. Verify that the 250ms minimum timeout meets your system's startup timing constraints. This part is ideal for cost-sensitive designs needing reliable voltage supervision in standard industrial temperature ranges.

Supervisors Part Context

The MAX1232 series belongs to Maxim Integrated’s line of microprocessor supervisory circuits designed for reliable power management. These devices are engineered to detect under-voltage conditions and generate reset signals to protect sensitive digital logic. The EWE+ variant specifically denotes the wide-body SSOP package option, offering a compact footprint for surface-mount assembly while maintaining robust performance characteristics typical of the broader MAX1232 product family.
