DS1706SEPA+

Supervisors Overview

The DS1706SEPA+ 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 threshold voltage of 3.3 V with an accuracy of 10%. The device provides power-fail detection and includes a watchdog timer, while lacking manual reset or battery backup switches. It utilizes a push-pull active low output type and offers a reset delay time of 205 ms. Designed for through-hole mounting in a PDIP-Narrow-8 package, it functions reliably across an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrated watchdog timer functionality for system monitoring
• Dedicated power-fail detection capability
• Push-pull active low output configuration

Supervisors Applications

• Microprocessor supervision
• Voltage monitoring in embedded systems
• Power management circuits requiring watchdog protection

Supervisors Procurement Notes

Verify component authenticity and datasheet alignment before integration. Confirm package compatibility and electrical specifications match design requirements. Check availability status as distribution may be limited. Ensure environmental compliance documentation is current. Validate pinout and thermal characteristics for the specific application environment.

Supervisors Selection Notes

Choose this component when a 3.3 V threshold with high accuracy is required alongside watchdog capabilities. Consider the PDIP-Narrow-8 package for through-hole assembly needs. Evaluate the 205 ms reset delay against system timing constraints. Assess the 60 uA operating current for power-sensitive designs. Verify that the absence of manual reset fits the control logic strategy.

Supervisors Part Context

This part belongs to the DS1706S series of MicroMonitor devices. It serves as a voltage supervisor designed for reliable operation in digital systems. The series typically offers various threshold options and packaging styles to suit different board layout and voltage monitoring requirements.

Supervisors Replacement Considerations

Direct substitutes include DS1706SEPA+ variants with identical suffixes. Cross-reference other DS1706 family members for similar features but different thresholds or packages.
