LTC1726EMS8-5

Supervisors Overview

The LTC1726EMS8-5#PBF is a triple supply monitor and power supervisor manufactured by Analog Devices. It features adjustable reset thresholds for three monitored inputs, with specific threshold voltages of 3.3V and 5V available alongside an adjustable option. The device operates within a maximum supply voltage of 7V and utilizes an MSOP-8 surface-mount package. It provides active low, open-drain outputs and includes an integrated watchdog timer with adjustable reset delay time. Manual reset functionality is not supported.

Supervisors Feature Summary

• Triple supply monitoring capability with adjustable reset thresholds
• Integrated watchdog timer with programmable reset delay
• Active low open-drain output configuration

Supervisors Applications

• Multi-rail embedded system power supervision
• Industrial control board voltage monitoring
• Telecommunications equipment power integrity management

Supervisors Procurement Notes

Verify component authenticity through authorized distribution channels due to limited availability status. Confirm the suffix #PBF indicates lead-free compliance and RoHS adherence. Validate the MSOP-8 package marking against official datasheet specifications to ensure correct identification during assembly and testing processes.

Supervisors Selection Notes

Select this component when simultaneous monitoring of three distinct voltage rails is required within a compact footprint. The adjustable reset delay and watchdog features suit applications demanding robust fault detection without manual intervention. Ensure the input voltage range remains below the 7V maximum limit during operation.

Supervisors Part Context

This part belongs to the Linear Technology (now Analog Devices) supervisory circuit portfolio, designed for reliable power management in space-constrained environments. The EMS8 designation identifies the specific MSOP-8 tape-and-reel compatible packaging variant within the broader LTC1726 family of multi-supply monitors.

Supervisors Replacement Considerations

Consult official Analog Devices documentation for verified cross-reference part numbers. Direct substitutes must match the triple-monitor architecture, MSOP-8 package, and active-low open-drain output characteristics to maintain circuit compatibility.
