DS1708SEPA

Supervisors Overview

The DS1708SEPA+ is a MicroMonitor voltage supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range up to 5.5 V and features a threshold voltage of 3.3 V with an accuracy of 10%. The device provides a reset delay time of 205 ms and draws a typical operating supply current of 60 uA. It supports active high, active low, and push-pull output types without manual reset or watchdog timer functionality. Designed for through-hole installation, it is housed in an 8-pin PDIP-Narrow package and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Monitors single power supply input for under-voltage conditions
• Provides configurable reset output signals including active high, active low, and push-pull options
• Detects power failure events independently of the reset function

Supervisors Applications

• Embedded system power supply monitoring
• Microprocessor reset circuit generation
• Battery-powered device voltage supervision

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to limited availability status. Confirm RoHS compliance details and specific manufacturing lot codes prior to procurement. Ensure packaging integrity matches the specified tube format. Cross-reference datasheet revisions to confirm pinout compatibility with existing designs.

Supervisors Selection Notes

Select this component when a through-hole supervisory circuit with a fixed 3.3 V threshold is required. Consider the 60 uA quiescent current for low-power applications. Verify that the 205 ms reset delay meets system timing requirements. Ensure the PDIP-Narrow-8 package fits the PCB layout constraints compared to surface-mount alternatives like the SOIC-8 variant.

Supervisors Part Context

This part belongs to the DS1708S series of MicroMonitor voltage supervisors. It shares functional similarities with other Maxim Integrated supervisory ICs but is distinguished by its specific threshold voltage and through-hole packaging. The series focuses on simple, cost-effective power management solutions for embedded electronics requiring reliable voltage monitoring.

Supervisors Replacement Considerations

Direct substitutes include DS1708ESA+ and DS1708SESA+. Note that these alternatives utilize surface-mount packages (SOIC-8) rather than the through-hole PDIP-Narrow-8 form factor. Verify footprint compatibility before substitution.
