DS1817-5+T&R

Supervisors Overview

The DS1817-5+T&R is a single-channel supervisory circuit from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It provides a reset signal with an active high output and features a push-pull or totem pole configuration. The device operates within a supply voltage range up to a 3.15 V overvoltage threshold and draws a typical operating supply current of 35 uA. Designed for surface-mount applications, it is available in SOT-23-3 packaging and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Active high reset output for direct logic interfacing
• Low power consumption suitable for battery-operated systems
• Robust operation under overvoltage conditions

Supervisors Applications

• Microprocessor system supervision
• Battery-powered electronic devices
• Portable instrumentation monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized distributors. Confirm package integrity and lead marking alignment with official datasheets. Ensure storage conditions comply with moisture sensitivity level requirements. Validate that the specific suffix matches design specifications before integration into production circuits.

Supervisors Selection Notes

Select this component when an active high reset signal is required for low-power applications. Consider the 35 uA supply current for energy-constrained designs. Verify that the 3.15 V overvoltage threshold aligns with the system's maximum operating voltage limits to ensure reliable protection.

Supervisors Part Context

This part belongs to the EconoReset family of supervisory circuits designed for cost-sensitive and space-constrained applications. It complements other Maxim Integrated reset solutions by offering a simplified interface with active high output capability, distinguishing it from standard open-drain variants in the product line.

Supervisors Replacement Considerations

Cross-reference with DS1816R-5+T&R if an active low output is acceptable. Verify pin compatibility and electrical characteristics against alternative single-channel supervisors from the same manufacturer series.
