DS1707ESA+

Supervisors Overview

The DS1707ESA+ is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for monitoring power supply voltages in electronic systems. It operates within a maximum supply voltage of 5.5 V and features a threshold voltage of 5 V with an accuracy of 5%. The device includes power-fail detection capabilities and provides a reset delay time of 205 ms. It supports active high, active low, and push-pull output types while consuming a working supply current of 60 uA. The overvoltage threshold is specified at 4.75 V. Designed for surface mount installation, it is housed in an SOIC-8 package and functions reliably across a temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Integrated power-fail detection mechanism for continuous voltage supervision
• Configurable output states supporting active high, active low, and push-pull configurations
• Low quiescent current consumption suitable for energy-efficient designs
• Dedicated overvoltage threshold monitoring capability

Supervisors Applications

• Microprocessor system voltage monitoring
• Power supply supervision in embedded controllers
• Battery backup system oversight
• Industrial control unit power integrity checks

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific packaging variants such as tube or tape-and-reel options prior to ordering. Ensure the selected part number matches the required operating temperature range and package style for your application. Request official datasheets and material declarations to validate technical specifications against project requirements.

Supervisors Selection Notes

Evaluate the DS1707ESA+ based on its single-input monitoring capability and fixed threshold characteristics. Consider the absence of manual reset and watchdog timer functions when designing system recovery logic. Compare the 205 ms reset delay against system startup timing requirements. Assess the SOIC-8 footprint compatibility with existing PCB layouts and verify that the 60 uA supply current aligns with overall power budget constraints.

Supervisors Part Context

This component belongs to the DS1707 series of MicroMonitor devices from Analog Devices/Maxim Integrated. These circuits are engineered for reliable voltage supervision in digital systems. The ESA+ suffix indicates a lead-free, RoHS-compliant variant packaged in standard SOIC format. This series represents a dedicated solution for maintaining system stability through precise voltage threshold detection without requiring external components for basic operation.
