DS1231-50

Supervisors Overview

The DS1231-50 is a power monitor chip designed to supervise input power and a 5V system supply. It utilizes precise, temperature-compensated comparators to detect voltage anomalies. The device features an overvoltage threshold of 5.5 V and operates with a supply current of 500 uA. It provides an open-drain or open-collector output for interfacing with processor systems.

Supervisors Feature Summary

• Monitors high voltage inputs to generate warnings before regulated DC voltages exceed specifications
• Provides time for orderly shutdown and prevents nonvolatile memory destruction during power transients
• Automatically restarts the processor after power is restored without requiring external capacitors

Supervisors Applications

• Processor-based systems requiring orderly shutdown capabilities
• Linear or switching power supply supervision
• Systems needing automatic restart after power restoration

Supervisors Procurement Notes

Verify the specific suffix (e.g., +) indicates lead-free compliance when ordering. Confirm package type availability, as the series includes both DIP and SOIC options. Ensure the selected variant matches the required monitoring thresholds for your specific 5V system design requirements.

Supervisors Selection Notes

Select this component for applications requiring precise voltage monitoring with temperature compensation. It is suitable for designs needing integrated power-up reset functionality and transient protection. Consider the available package formats based on board space constraints and assembly methods.

Supervisors Part Context

This part belongs to the DS1231 family of power monitor chips from Maxim Integrated. These devices are engineered to replace traditional power-up reset circuits by offering comprehensive power supervision. The family supports various monitoring thresholds and package configurations to suit different embedded system architectures.

Supervisors Replacement Considerations

Direct substitutes within the DS1231 series may offer different package types such as the surface-mount SOIC variant. Verify that any replacement maintains the same 5V monitoring capability and output interface characteristics.
