DS1232LPSN-2

Supervisors Overview

The DS1232LPSN-2 is a low-power MicroMonitor supervisory circuit designed for microprocessor systems. It monitors a single voltage supply within the 4.5 V to 5.5 V range, with a specific threshold of 4.62 V to 4.74 V. The device features a manual reset input and provides active-high, active-low, and open-drain outputs. It includes a watchdog timer with a 1000 ms timeout period. Operating temperatures range from -40°C to +85°C in an 8-pin SOIC package.

Supervisors Feature Summary

• Integrates power monitoring, manual reset control, and watchdog timer functions into a single chip
• Provides multiple output driver configurations including high-level, low-level, and open-drain options
• Supports battery backup switching to maintain system integrity during power transitions

Supervisors Applications

• Microprocessor power supply supervision
• Embedded system reset management
• Watchdog timer implementation for fault recovery

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm package markings and datasheet revisions match the specific lot requirements. Check for alternative sources if original manufacturing lines are unavailable. Ensure compliance with current environmental regulations for legacy components.

Supervisors Selection Notes

Select this component when a combined supervisory solution is required for 5V logic systems. Consider the manual reset capability and watchdog timeout duration against system timing requirements. Evaluate the SOIC-8 footprint constraints and thermal performance within the specified operating temperature range.

Supervisors Part Context

This part belongs to the Maxim Integrated DS1232 family of MicroMonitor chips. These devices combine essential supervisory functions to simplify design. The LPSN suffix indicates the specific package type and pin configuration suitable for surface-mount applications.

Supervisors Replacement Considerations

Consult official documentation for cross-reference data. Verify functional compatibility regarding threshold voltages and output drive capabilities before substitution.
