MAX1232EWE+T

Supervisors Overview

The MAX1232EWE+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage supply and provides a reset signal when the supply drops below a specific threshold. The device features an open-drain or open-collector output that can be configured for active-high or active-low reset assertions. It includes a programmable timeout to ensure stable power-up conditions before releasing the reset line. The component operates within a temperature range of -40°C to +85°C and is housed in an 8-SOIC surface-mount package.

Supervisors Feature Summary

• Monitors a single voltage rail with a fixed threshold
• Configurable reset output polarity and type
• Programmable reset timeout duration

Supervisors Applications

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

Supervisors Procurement Notes

Verify the exact threshold voltage variant required, as the MAX1232 series offers multiple fixed options. Confirm the package suffix matches the design footprint. Check current availability status as older Maxim parts may have limited stock or end-of-life implications. Ensure the selected variant supports the required operating temperature range for the target environment.

Supervisors Selection Notes

Select this component when a simple, single-supervisor function is needed without complex sequencing. Compare against other MAX123x variants if different thresholds or manual reset inputs are required. Consider the SOIC package constraints for PCB layout. Verify compatibility with the system's logic levels for the reset output interface.

Supervisors Part Context

This part belongs to the MAX1232 family of simple reset supervisors. It is designed for applications requiring basic power-on reset functionality. The EWE+T suffix indicates the industrial temperature grade, SOIC-8 package, tape-and-reel packaging, and lead-free/RoHS compliance. It serves as a fundamental building block for ensuring reliable system startup in digital circuits.

Supervisors Replacement Considerations

Direct replacements include other MAX1232 variants with matching threshold voltages and package types. Cross-reference with DS1232 series parts for similar functionality from the same manufacturer lineage. Ensure any substitute maintains the same reset timeout characteristics and output drive capabilities.
