DS1708RESA

Supervisors Overview

The DS1708RESA is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed as a MicroMonitor for 3.3V and 5.0V systems. It operates within a supply voltage range up to 5.5V and features a reset delay time of 285 ms. The device monitors one input with an overvoltage threshold of 4.5V and consumes 60 uA of operating current. It supports active high, active low, and push-pull output types without manual reset or watchdog timer functions. The component is available in SOIC-Narrow-8 packaging and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides power failure detection capabilities for system monitoring
• Supports multiple output configurations including active high, active low, and push-pull modes
• Operates with low quiescent current consumption suitable for battery-backed applications

Supervisors Applications

• Monitoring 3.3V and 5.0V power rails in embedded systems
• Supervising voltage levels in industrial control equipment
• Ensuring system stability in consumer electronics requiring reliable power management

Supervisors Procurement Notes

Verify the specific suffix and package variant when sourcing, as availability may be limited. Confirm RoHS compliance status and manufacturing origin through official documentation. Check for obsolescence notices or lifecycle restrictions before finalizing procurement plans. Ensure compatibility with existing board layouts regarding the SOIC-Narrow-8 footprint.

Supervisors Selection Notes

Select this component when a single-input voltage supervisor with configurable outputs is required. Consider the 285 ms reset delay and 4.5V overvoltage threshold against system timing requirements. Evaluate the 60 uA current draw against power budget constraints. Verify that the absence of a manual reset or watchdog feature aligns with the application's safety logic design.

Supervisors Part Context

The DS1708RESA belongs to the DS1708 series of MicroMonitors from Maxim Integrated, now part of Analog Devices. This family focuses on providing essential voltage supervision for digital circuits without complex configuration needs. The RESA designation typically indicates a specific thermal grade and package variation within the broader product line, ensuring reliability in standard surface-mount assembly processes.

Supervisors Replacement Considerations

Consult official cross-reference lists for direct replacements. Verify pinout compatibility and electrical parameter alignment, particularly threshold voltages and reset delays, before substituting.
