DS1708SEUA/T&R

Supervisors Overview

The DS1708SEUA/T&R is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single input voltage with thresholds at 3.3 V and 5 V. The device features active high, active low, and push-pull outputs. It includes power-fail detection but lacks a manual reset or watchdog timer. The reset delay time is 285 ms. Operating voltage ranges from unspecified minimum to 5.5 V maximum. It operates within a temperature range of -40°C to +85°C. The part is housed in an SOIC-Narrow-8 package.

Supervisors Feature Summary

• Monitors single input voltage with defined threshold levels
• Provides multiple output configurations including active high, active low, and push-pull
• Includes power-fail detection capability

Supervisors Applications

• Voltage supervision for 3.3 V systems
• Voltage supervision for 5.0 V systems
• Power management integrated circuits

Supervisors Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel configuration. Confirm RoHS compliance status through manufacturer datasheets. Check current availability as distribution channels may indicate limited stock or restricted sales regions. Ensure the ordering part number matches the required pinout and electrical specifications for the target application design.

Supervisors Selection Notes

Select this component when monitoring a single voltage rail requiring configurable output polarity. The absence of a watchdog timer and manual reset distinguishes it from other supervisory ICs. Verify that the 285 ms reset delay meets system startup timing requirements. Ensure the operating temperature range covers the intended environmental conditions.

Supervisors Part Context

This part belongs to the DS1708S series of MicroMonitor devices. These are simple reset/power supply supervisor circuits designed for embedded applications. The series typically offers low quiescent current and compact packaging options suitable for space-constrained designs.

Supervisors Replacement Considerations

DS1708SESA+T&R shares similar supervisory functions but differs in package type.
