DS1706TEUA+

Supervisors Overview

The DS1706TEUA+ is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.2 V to 5.5 V and features a 3.3 V threshold voltage with 5% accuracy. The device provides an active low, push-pull output and includes a built-in watchdog timer. It has a reset delay time of 205 ms and consumes 60 uA of operating current. The component supports power-fail detection but lacks manual reset and battery backup switching capabilities. It is housed in an USOP-8 package and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides power-fail warning detection capability
• Features active low push-pull output configuration

Supervisors Applications

• Microprocessor system supervision
• Portable equipment power management
• Battery-operated systems requiring low quiescent current

Supervisors Procurement Notes

Verify the specific suffix TEUA against official datasheets to confirm the USOP-8 package and 3.3V threshold specifications. Confirm RoHS compliance status as indicated in manufacturer documentation. Check availability constraints as distribution channels may report limited stock or discontinuation statuses that differ from official lifecycle data. Ensure the ordering part number matches the exact functional requirements before procurement.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with integrated watchdog functionality is required. The USOP-8 package suits space-constrained surface-mount designs. Verify that the 3.3V threshold aligns with the monitored rail. Consider the 60 uA quiescent current for battery life calculations. Ensure the absence of manual reset meets the design logic requirements.

Supervisors Part Context

This part belongs to the DS1706T series of MicroMonitor circuits. It is designed for simple reset and power-fail applications. The series typically offers various threshold voltages and packages. The TEUA suffix specifically denotes the USOP-8 surface-mount package variant with a 3.3V threshold.

Supervisors Replacement Considerations

Direct replacements include other DS1706 variants with matching thresholds and packages. Cross-brand alternatives require verification of pin compatibility and electrical parameters such as reset delay and quiescent current.
