DS1707EUA

Supervisors Overview

The DS1707EUA+ is a MicroMonitor voltage supervisor designed for 3.3V and 5.0V systems, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range up to 5.5V with a typical quiescent current of 60µA. The device features a fixed threshold voltage of 5V and an overvoltage detection limit of 4.75V. It provides a reset delay time of 205ms and maintains accuracy within 5%. Operating temperatures span from -40°C to +85°C. The component utilizes an 8-USOP surface-mount package and includes power-fail detection capabilities without manual reset or watchdog timer functions.

Supervisors Feature Summary

• Monitors single input voltage for under-voltage and over-voltage conditions
• Provides active high, active low, and push-pull output configurations
• Detects power failure events independently of the reset signal

Supervisors Applications

• Portable equipment requiring battery backup monitoring
• Microprocessor system supervisory circuits
• Smart cards and smart card controllers

Supervisors Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and electrical characteristics, as variations exist within the family. Confirm RoHS compliance status through manufacturer documentation. Note that availability may be restricted in certain regions. Ensure the selected package matches the PCB footprint requirements for the USOP-8 configuration.

Supervisors Selection Notes

Select this component when a simple, low-power voltage monitor is required for standard logic levels. Consider the 205ms reset delay duration relative to system startup timing requirements. Evaluate the 5% accuracy specification against circuit tolerance needs. Verify that the absence of a manual reset pin aligns with the design architecture.

Supervisors Part Context

This part belongs to the Maxim Integrated MicroMonitor series, which focuses on low-cost, low-power supervision solutions. The DS1707 variant specifically targets applications needing simultaneous monitoring of multiple voltage rails or specific threshold detection in compact packages. It serves as a foundational component for ensuring system stability during power transitions.

Supervisors Replacement Considerations

Consult official substitution guides for compatible parts within the DS1707 family. Verify pin compatibility and electrical parameter alignment before replacing.
