DS1706SESA

Supervisors Overview

The DS1706SESA+ is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 3.3 V for monitoring a single input. The device provides an active low, push-pull output with a reset delay time of 205 ms. It includes an integrated watchdog timer and power-fail detection capabilities but lacks manual reset and battery backup switching functions. Accuracy is specified at 10%. The component is housed in an SOIC-8 package and supports surface mount installation. It functions without a chip enable signal and draws a typical operating supply current of 60 uA.

Supervisors Feature Summary

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

Supervisors Applications

• Microprocessor system supervision
• Voltage monitoring for 3.3V logic circuits
• Watchdog timer implementation in embedded systems

Supervisors Procurement Notes

Verify the exact suffix designation when ordering, as variants such as DS1706SESA+T&R indicate tape-and-reel packaging while others may use tubes. Confirm RoHS compliance status through official documentation, as some legacy versions may not meet current environmental standards. Check availability constraints, as limited supply situations may affect procurement timelines. Ensure the selected package matches the PCB footprint requirements for SOIC-8 mounting.

Supervisors Selection Notes

Select this component when a fixed 3.3V threshold is required for single-channel voltage monitoring. Consider the 205 ms reset delay and 10% accuracy specifications against system timing requirements. Evaluate the need for watchdog functionality versus simpler reset-only supervisors. Compare operating current consumption of 60 uA against low-power design goals. Verify that the SOIC-8 package fits the available board space compared to alternatives like TSSOP or uMAX packages.

Supervisors Part Context

The DS1706 series belongs to Maxim Integrated's MicroMonitor family of supervisory circuits. These devices are designed to monitor voltage levels and provide reset signals to microprocessors and memory devices. The SE variant specifically denotes the 3.3V threshold version packaged in SOIC-8 format. This family integrates watchdog and power-fail features into a compact solution for reliable system operation.

Supervisors Replacement Considerations

Direct substitute part numbers include DS1706SESA+. Other potential replacements from different manufacturers should be evaluated based on matching threshold voltages, package dimensions, and functional equivalents such as integrated watchdog timers.
