DS1708SESA+T&R

Supervisors Overview

The DS1708SESA+T&R is a voltage supervisory circuit from the MicroMonitor family, designed for monitoring single power supply rails. It features a fixed threshold voltage of 3.3 V and an overvoltage detection threshold of 3 V. The device operates within a maximum supply voltage of 5.5 V and draws a typical quiescent current of 60 uA. It provides active high and active low push-pull outputs with a reset delay time of 285 ms. Accuracy is specified at 10%. The component supports power-fail detection and lacks manual reset or watchdog timer functions. It is housed in an SOIC-Narrow-8 package and operates across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Monitors a single input voltage rail with dedicated overvoltage detection capabilities
• Provides dual active high and active low push-pull output signals for flexible logic interfacing
• Integrates power-fail detection functionality alongside standard voltage supervision

Supervisors Applications

• Monitoring 3.3 V logic supplies in embedded systems
• Supervising 5.0 V power rails in industrial control equipment
• Ensuring system stability in microcontroller-based designs requiring undervoltage protection

Supervisors Procurement Notes

Verify the specific suffix T&R indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check current availability as distribution channels may list restricted supply conditions. Ensure the SOIC-Narrow-8 footprint matches the target PCB layout requirements for surface mount installation.

Supervisors Selection Notes

Select this component when a single-channel supervisor with both under- and over-voltage monitoring is required. The 3.3 V threshold suits standard logic levels, while the 3 V overvoltage point provides margin. Consider the 285 ms reset delay for timing constraints. The absence of a manual reset pin simplifies design but limits user intervention. Compare quiescent current against battery life requirements if applicable.

Supervisors Part Context

This part belongs to the Maxim Integrated MicroMonitor series, which focuses on simple, cost-effective voltage supervision solutions. The DS1708 variant specifically targets applications needing simultaneous under- and over-voltage tracking without complex configuration. It complements other devices in the family that may offer different thresholds or additional features like watchdog timers.
