LTC1726EMS8-2.5#PBF

Supervisors Overview

The LTC1726EMS8-2.5#PBF is a triple supply monitor and microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within an input voltage range of 2.65 V to 6 V, with a maximum supply voltage of 7 V. The device features three monitored inputs with threshold voltages of 3.3 V, 5 V, and an adjustable setting. It draws a typical quiescent current of 20 uA and provides active low, open-drain outputs. The component supports adjustable reset delay times and includes a watchdog timer function. It is housed in an MSOP-8 package and functions as a supervisory circuit for systems requiring multiple power rail monitoring.

Supervisors Feature Summary

• Integrates triple supply monitoring with dedicated open-drain outputs for individual power rail supervision
• Includes microprocessor supervisor functionality with configurable reset timing and watchdog timer capabilities
• Supports fixed thresholds at 3.3 V and 5 V alongside an adjustable voltage reference for flexible system design

Supervisors Applications

• Systems requiring simultaneous monitoring of multiple distinct supply voltages
• Microprocessor-based designs needing integrated reset generation and watchdog protection
• Embedded applications utilizing adjustable voltage thresholds for custom power sequencing

Supervisors Procurement Notes

Verify the specific suffix #PBF confirms lead-free compliance and RoHS standards before procurement. Confirm the -2.5 designation matches the required threshold configuration for your application. Check current availability status as distribution may be limited or subject to factory order constraints. Ensure the MSOP-8 footprint aligns with your PCB layout requirements.

Supervisors Selection Notes

Select this component when a single IC must monitor three separate power rails while providing processor reset and watchdog functions. The adjustable threshold offers flexibility for non-standard voltage levels. Compare the 20 uA quiescent current against battery life requirements. Verify that the open-drain output structure suits the logic levels of the connected microprocessor.
