LTC1726IS8-5#PBF

Supervisors Overview

The LTC1726IS8-5#PBF is a triple supply monitor and microprocessor supervisory circuit manufactured by Analog Devices Inc. It features adjustable reset functions and an integrated watchdog timer, designed for systems requiring multiple voltage supervision. The device operates within a supply voltage range of up to 7 V and supports three monitored inputs with threshold voltages of 3.3 V, 5 V, and an adjustable level. It utilizes an SOIC-8 surface-mount package and maintains low power consumption with a typical operating current of 20 uA.

Supervisors Feature Summary

• Provides simultaneous monitoring of three distinct supply voltages including fixed 3.3 V and 5 V thresholds alongside one adjustable channel
• Integrates a programmable watchdog timer to ensure system reliability through automated recovery from software faults
• Features adjustable reset delay timing to accommodate specific startup sequence requirements in complex embedded architectures

Supervisors Applications

• Microprocessor supervisory circuits in multi-rail embedded systems
• Industrial control units requiring robust power failure detection
• Communication equipment needing reliable watchdog functionality

Supervisors Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm pinout compatibility and electrical specifications. Confirm RoHS compliance status directly with the manufacturer or authorized distributors as regulatory details may vary by production batch. Ensure the SOIC-8 footprint matches your PCB design constraints before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when designing systems that require independent supervision of three separate power rails without external comparator complexity. The inclusion of an adjustable reset delay allows flexibility for different startup sequences. Consider the low quiescent current suitable for battery-backed or energy-efficient applications where standby power consumption is critical.

Supervisors Part Context

This part belongs to the LTC1726 series of supervisory circuits from Analog Devices. It serves as a dedicated solution for managing power integrity in digital systems. The IS8-5 variant specifically denotes the industrial temperature range and the specific threshold configuration for the three monitored channels within the standard SOIC-8 package format.

Supervisors Replacement Considerations

Consult official Analog Devices cross-reference guides for verified substitutes. Ensure any replacement maintains triple-supervision capability and compatible SOIC-8 packaging.
