DS1239-10+

Supervisors Overview

The DS1239-10+ is a MicroManager supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a temperature range of 0°C to 70°C and utilizes a 16-PDIP through-hole package. The device monitors a single voltage channel with a threshold of 4.37V, providing a low-active reset signal with a minimum timeout of 25ms. Its output configuration supports open-drain or open-collector connections.

Supervisors Feature Summary

• Monitors power supply voltage for system integrity
• Provides controlled reset signals during power transients
• Supports orderly shutdown procedures for nonvolatile memory

Supervisors Applications

• Nonvolatile microprocessor applications requiring controlled shutdown
• Battery-operated handheld devices needing low-power stop mode control
• Systems requiring backup battery circuit supervision

Supervisors Procurement Notes

Verify the specific suffix designation carefully, as the DS1239-10+ indicates RoHS compliance compared to the non-compliant DS1239-10. Confirm current availability status, as this component may be discontinued. Ensure the 16-PDIP package matches your PCB footprint requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when an industrial-grade temperature range is not required, as it is rated for commercial temperatures only. Choose this part if an open-drain or open-collector reset output is preferred over push-pull configurations. Verify that the 4.37V threshold aligns with your specific power supply monitoring needs.

Supervisors Part Context

This component belongs to the MicroManager series, designed for comprehensive power management in embedded systems. It integrates functions such as power-fail warning and write-protection control. The device simplifies the design of reliable systems by managing power transitions and protecting data integrity during unexpected power loss events.

Supervisors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative MicroManager series components based on pinout and electrical specifications.
