DS1817-5+

Supervisors Overview

The DS1817-5+ is a supervisory circuit from the EconoReset series by Analog Devices Inc./Maxim Integrated. It functions as an active high voltage monitor with a fixed threshold of 3.3V. The device features a push-pull, totem pole output and includes a minimum reset delay time of 100ms. It is housed in a TO-92-3 package and supports single-input monitoring without manual reset or watchdog timer capabilities.

Supervisors Feature Summary

• Provides active high supervision for power rails
• Integrated push-pull output stage
• Fixed 3.3V detection threshold

Supervisors Applications

• Microprocessor system power monitoring
• Battery-powered device supervision
• Embedded controller reset generation

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to limited supply status. Confirm RoHS compliance documentation matches current manufacturing standards. Check datasheet revisions for any parameter updates prior to integration into final designs.

Supervisors Selection Notes

Select this part when an active high output is required for downstream logic compatibility. The TO-92-3 package suits through-hole mounting constraints. Ensure the 3.3V threshold aligns with the monitored rail's nominal voltage and noise margins.

Supervisors Part Context

Part of the Maxim Integrated EconoReset family designed for cost-sensitive applications. This specific model targets 3.3V systems requiring simple, reliable reset signaling without complex configuration options.

Supervisors Replacement Considerations

Cross-reference with other active high supervisors in the same series. Verify pinout compatibility and threshold voltage accuracy before substituting.
