DS1708REUA/T&R

Supervisors Overview

The DS1708REUA/T&R 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 overvoltage threshold of 4.5 V. The device provides a reset delay time of 285 ms and consumes a working power supply current of 60 uA. It supports active high, active low, and push-pull output types for a single monitored input. The component is housed in an 8-UMAX package and functions without manual reset, watchdog timer, or battery backup switch capabilities.

Supervisors Feature Summary

• Monitors system power supply voltages to ensure stable operation
• Provides configurable reset signals via active high, active low, or push-pull outputs
• Detects power failure conditions for system protection

Supervisors Applications

• Embedded systems requiring voltage supervision
• Portable electronic devices needing low-power monitoring
• Industrial control circuits with single-rail power supplies

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolete status. Confirm RoHS compliance details as specified in official documentation. Ensure the specific suffix matches required packaging formats such as tape and reel. Cross-reference datasheet revisions to validate electrical parameters against current design requirements before integration.

Supervisors Selection Notes

Select this component when a simple, low-current voltage monitor is required for single-input applications. Consider the 285 ms reset delay and 60 uA quiescent current for timing-sensitive or battery-powered designs. Verify that the 8-UMAX package fits the PCB layout constraints. Evaluate if the absence of manual reset or watchdog features aligns with system safety needs.
