DS1706REUA

Supervisors Overview

The DS1706REUA+ is a MicroMonitor voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.2 V to 5.5 V and monitors a single input channel with a threshold of 3.3 V. The device features an active low, push-pull output and includes a watchdog timer for system protection. It provides power-fail detection and has a reset delay time of 205 ms. The component functions in temperatures from -40°C to +85°C, consumes 60 µA of operating current, and lacks manual reset or battery backup switching capabilities.

Supervisors Feature Summary

• Integrates a watchdog timer for automated system recovery
• Provides power-fail warning detection capability
• Features active low push-pull output structure

Supervisors Applications

• Embedded system power supervision
• Microcontroller reset management
• Portable electronic device monitoring

Supervisors Procurement Notes

Verify the exact suffix against official datasheets to confirm package type and electrical characteristics. Confirm RoHS compliance status as specifications may vary by manufacturing batch. Ensure compatibility with existing PCB footprint and thermal requirements before integration into final designs.

Supervisors Selection Notes

Select this component when a fixed 3.3 V threshold is required for single-channel monitoring. Consider the USOP-8 package constraints for space-limited designs. Evaluate the 205 ms reset delay against system startup timing requirements to ensure proper initialization sequences are maintained during power events.

Supervisors Part Context

This part belongs to the DS1706R series of MicroMonitor circuits designed for simple voltage supervision. It serves as a dedicated supervisory solution for low-voltage digital systems requiring reliable reset generation without complex configuration interfaces.

Supervisors Replacement Considerations

DS1706RESA+ offers identical electrical performance in an SOIC-8 package. DS1706REPA+ provides similar functionality in a PDIP-8 package but includes a manual reset input feature.
