LTC1727ES8-2.5#PBF

Supervisors Overview

The LTC1727ES8-2.5#PBF is a micropower precision triple supply monitor manufactured by Analog Devices Inc. It is designed for systems requiring supervision of multiple voltage rails. The device features three independent open-drain outputs, each dedicated to monitoring a specific supply voltage. The part number suffix indicates fixed threshold voltages of 3.086V, 2.338V, and an adjustable setting for the third channel. It operates within a specified temperature range and is housed in an 8-pin MSOP package.

Supervisors Feature Summary

• Provides independent monitoring for three distinct power supply rails
• Features open-drain outputs for flexible logic interface compatibility
• Designed for micropower operation suitable for battery-powered applications

Supervisors Applications

• Systems with multiple supply voltages
• JFET circuit monitoring
• Processor supervisor circuits

Supervisors Procurement Notes

Verify the exact ordering suffix against the manufacturer's current documentation. Suffixes such as #PBF indicate lead-free status and RoHS compliance. Confirm package type and thermal specifications match your PCB layout requirements. Check for any recent product change notices that may affect pinout or electrical characteristics before finalizing procurement.

Supervisors Selection Notes

Select this component when simultaneous supervision of three separate voltage rails is required without external comparator complexity. Ensure the fixed thresholds of 3.086V and 2.338V align with your system's critical voltage levels. Consider the adjustable third channel for custom threshold needs. Verify that the open-drain output configuration fits your downstream logic family requirements.

Supervisors Part Context

This component belongs to the LTC1727 series of triple supply monitors from Analog Devices. It shares functional similarities with other parts in the family but differs in specific threshold configurations and package options. The ES8 designation typically refers to the industrial temperature grade and MSOP packaging variant within the broader product line.

Supervisors Replacement Considerations

LTC1727IS8-2.5#TR is a related variant with tape-and-reel packaging. Cross-reference datasheets to confirm identical electrical parameters and pinouts before substitution.
