DS1708EUA

Supervisors Overview

The DS1708EUA+ is a MicroMonitor voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of up to 5.5 V and monitors a single input channel. The device features configurable threshold voltages of 3.3 V and 5.0 V, with an overvoltage detection threshold at 4.5 V. It provides active high, active low, or push-pull output types without manual reset or watchdog timer functionality. The reset delay time is specified at 285 ms, and the quiescent current is 60 uA. It functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Configurable voltage thresholds for 3.3 V and 5.0 V monitoring applications
• Supports multiple output configurations including active high, active low, and push-pull
• Integrated power-fail detection capability for system protection

Supervisors Applications

• Microprocessor reset circuits in embedded systems
• Power supply monitoring for digital logic interfaces
• Overvoltage protection in portable electronic devices

Supervisors Procurement Notes

Verify the exact suffix configuration against official datasheets to ensure correct package type and electrical characteristics. Confirm RoHS compliance status and manufacturing origin prior to procurement. Check for obsolescence notices or lifecycle changes directly from Analog Devices documentation. Ensure compatibility with existing board layout constraints regarding the UMAX-8 package dimensions.

Supervisors Selection Notes

Select this component when a single-channel supervisor with flexible output polarity is required. Consider the 285 ms reset delay for timing-sensitive designs. Evaluate the 60 uA quiescent current against battery life requirements. Verify that the 3.3 V and 5.0 V thresholds align with the target system voltage rails. Confirm no manual reset or watchdog features are needed for the specific application.

Supervisors Part Context

The DS1708 belongs to the Maxim Integrated MicroMonitor family of voltage supervisors. These components are designed to provide reliable reset signals for microprocessors and memory devices. The series emphasizes low power consumption and small footprint solutions suitable for space-constrained electronics. Analog Devices acquired Maxim Integrated, integrating these products into their broader portfolio.
