DS1708SEPA+

Supervisors Overview

The DS1708SEPA+ is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of up to 5.5 V and features a threshold voltage of 3.3 V with an accuracy of 10%. The device provides power-fail detection and utilizes a reset delay time of 205 ms. It draws a working supply current of 60 uA and includes overvoltage threshold detection at 3 V. The component supports active high, active low, and push-pull output types without manual reset or watchdog timer functionality. It is housed in a PDIP-Narrow-8 package and functions across a temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Monitors single input voltage for power failure conditions
• Provides configurable active high, active low, or push-pull outputs
• Includes overvoltage threshold detection capability

Supervisors Applications

• Embedded system power supervision
• Microcontroller reset generation
• Portable electronic device monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to limited availability status. Confirm package integrity and RoHS compliance before integration. Check manufacturing date codes against project requirements. Ensure storage conditions maintain specified operational parameters. Validate pinout compatibility with existing PCB layouts prior to procurement.

Supervisors Selection Notes

Select this component when precise 3.3 V monitoring is required with low standby current consumption. Consider the PDIP-Narrow-8 package for through-hole mounting applications. Evaluate the 205 ms reset delay against system startup timing requirements. Compare against alternatives if manual reset or watchdog features are necessary.

Supervisors Part Context

This part belongs to the DS1708S series of MicroMonitor circuits designed for simple voltage supervision tasks. It serves as a cost-effective solution for basic power management needs in industrial and consumer electronics. The series emphasizes reliability and low power consumption for continuous monitoring applications.

Supervisors Replacement Considerations

DS1708ESA+ offers similar functionality in SOIC-8 surface mount packaging with a 5 V threshold.
