DS1706ESA

Supervisors Overview

The DS1706ESA is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.2 V to 5.5 V and features a fixed threshold voltage of 5 V with 10% accuracy. The device provides an active low, push-pull output and includes a built-in watchdog timer. It offers a reset delay time of 205 ms and consumes only 60 uA of operating current. The component supports power failure detection and lacks manual reset or battery backup switching capabilities. It is housed in an SOIC-Narrow-8 package and functions reliably across an industrial temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Integrates a watchdog timer for system stability monitoring alongside voltage supervision.
• Features power failure detection capability to ensure data integrity during transient events.
• Delivers an active low push-pull output signal for direct interface with digital logic.

Supervisors Applications

• Embedded systems requiring reliable power supervision
• Industrial control units needing watchdog functionality
• Portable devices with strict current consumption limits

Supervisors Procurement Notes

Verify the specific suffix designation when ordering, as packaging formats vary between tube and reel configurations. Confirm availability status directly with authorized distributors, as supply constraints may apply to this component. Ensure the selected variant matches the required threshold voltage and package type for your design. Cross-reference the datasheet for precise electrical characteristics relevant to your application environment.

Supervisors Selection Notes

Select the DS1706ESA when a fixed 5 V threshold is appropriate for the monitored rail. Consider the 10% accuracy specification against system tolerance requirements. Evaluate the 60 uA quiescent current impact on overall battery life if applicable. Verify that the SOIC-Narrow-8 footprint aligns with PCB layout constraints. Assess whether the integrated watchdog timer meets the system's fault recovery needs without external components.

Supervisors Part Context

This component belongs to the DS1706 series of MicroMonitor circuits designed for comprehensive system management. It combines voltage monitoring with watchdog timing in a single compact package. The series targets applications demanding high reliability and low power consumption. Analog Devices utilizes this architecture to provide robust supervision for microprocessor-based systems.

Supervisors Replacement Considerations

Check for DS1706SESA+ variants if a 3.3 V threshold is required instead of 5 V. Review DS1706TESA+ options for tighter accuracy specifications if precision is critical. Ensure pin compatibility and functional equivalence before substituting any alternative part numbers.
