DS1708TESA/T&R/

Supervisors Overview

The DS1708TESA+ is a supervisory circuit from the Analog Devices Maxim Integrated MicroMonitor series, designed for monitoring 3.3V and 5.0V power rails. It features a single monitored input with a threshold voltage of 3.3V and an overvoltage threshold of 3.15V. The device operates within a supply voltage range up to 5.5V, consuming 60µA. It provides active high, active low, and push-pull outputs with a reset delay of 205ms. Accuracy is specified at 5%, and it functions between -40°C and +85°C in an SOIC-8 package.

Supervisors Feature Summary

• Monitors specific voltage rails including 3.3V and 5.0V inputs
• Provides multiple output types: active high, active low, and push-pull
• Includes power failure detection capabilities
• Operates without manual reset or watchdog timer functions

Supervisors Applications

• Monitoring 3.3V and 5.0V microprocessor power supplies
• Supervising voltage levels in portable electronic systems
• Ensuring system stability in industrial control applications

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm package type matches design requirements as tape-and-reel options may differ from tube packaging. Check datasheet for exact electrical characteristics relevant to specific application conditions before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when precise monitoring of standard logic voltages is required. Consider the 5% accuracy specification against system tolerance requirements. Evaluate the absence of manual reset and watchdog features against system design needs. Ensure operating temperature range meets environmental constraints for the intended deployment scenario.

Supervisors Part Context

This part belongs to the DS1708T series of MicroMonitor devices. It serves as a dedicated voltage supervisor within the broader portfolio of power management integrated circuits offered by Analog Devices. The component complements other supervisory solutions by providing targeted monitoring for common digital logic voltage levels.

Supervisors Replacement Considerations

DS1707ESA+ offers similar functionality with a 5V threshold. DS1706TESA+ provides comparable monitoring capabilities. Verify pinout compatibility and threshold voltage alignment when substituting these alternatives.
