DS1707EUA+T&R

Supervisors Overview

The DS1707EUA+T&R is a MicroMonitor supervisory circuit manufactured by Analog Devices / Maxim Integrated. It operates within a supply voltage range of up to 5.5 V and monitors a single input with a threshold of 5 V. The device features active high, active low, and push-pull outputs with a reset delay time of 205 ms. It has no manual reset, watchdog timer, or battery backup switch. Operating temperatures range from -40 C to +85 C with 5% accuracy and a working power current of 60 uA. Overvoltage detection is set at 4.75 V. It is housed in an USOP-8 package.

Supervisors Feature Summary

• Monitors 3.3 and 5.0 volt power rails for system stability
• Provides configurable output states including active high, active low, and push-pull configurations
• Detects power failure conditions without requiring manual reset or external watchdog components

Supervisors Applications

• Portable system controller supervision
• Battery-powered equipment monitoring
• General microprocessor reset circuits

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm tape and reel packaging specifications. Confirm RoHS compliance status through the latest datasheet revision. Check for obsolescence notices as this component family may have limited availability. Ensure the ordering part number matches the required package type and temperature grade before procurement.

Supervisors Selection Notes

Select this component when a single-input voltage monitor with multiple output polarity options is required. The integrated overvoltage detection capability supports applications needing protection against supply spikes. The low operating current makes it suitable for battery-operated devices where standby power consumption must be minimized. Verify that the 205 ms reset delay meets the timing requirements of the target microprocessor.

Supervisors Part Context

The DS1707 belongs to the Maxim Integrated MicroMonitor series designed for supervising digital logic systems. These circuits are engineered to provide reliable reset signals during power-up and power-down sequences. The USOP-8 package allows for compact surface-mount integration in space-constrained designs. This series typically targets cost-sensitive consumer and industrial electronics applications.
