LTC1727IS8-2.5#TRPBF

Supervisors Overview

The LTC1727IS8-2.5#TRPBF is a micropower precision triple supply monitor manufactured by Analog Devices Inc., housed in an SOIC-8 surface-mount package. It operates within an input voltage range of 2.5 V to 7 V with a quiescent current of 15 uA. The device monitors three independent supply rails, featuring fixed thresholds for two channels and an adjustable threshold for the third. It provides active-low open-drain reset outputs and includes a watchdog timer with an adjustable timeout period to ensure system reliability under varying operating conditions.

Supervisors Feature Summary

• Monitors three independent power supply voltages simultaneously
• Features one adjustable threshold channel alongside two fixed thresholds
• Includes a programmable watchdog timer with adjustable timeout duration
• Delivers active-low open-drain reset signals for system supervision

Supervisors Applications

• Portable battery-powered equipment requiring multi-rail monitoring
• Embedded systems needing watchdog protection against software faults
• Industrial control units supervising critical logic and analog supplies

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the SOIC-8 package variant matches your PCB footprint requirements. Ensure the manufacturer designation aligns with Analog Devices Inc. specifications. Cross-reference the datasheet revision date to confirm feature consistency. Validate RoHS compliance status through official documentation before integration.

Supervisors Selection Notes

Select this component when designing circuits requiring simultaneous supervision of three distinct voltage rails. The adjustable threshold offers flexibility for custom trip points on one channel. Consider the low 15 uA quiescent current for battery-operated applications where standby power consumption is critical. The integrated watchdog timer simplifies design by reducing external component count compared to discrete solutions.

Supervisors Part Context

This part belongs to the LTC1727 series of micropower precision triple supply monitors from Analog Devices. It shares functional similarities with other members of the family but differs in package type and specific threshold configurations. The IS8 designation identifies the industrial temperature range and SOIC-8 package format, distinguishing it from MSOP or SOT-23 variants within the same product line.
