LTC1326CMS8-2.5#TRPBF

Supervisors Overview

The LTC1326CMS8-2.5#TRPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for microprocessor monitoring applications. It features three independent voltage monitor inputs with threshold voltages of 3.3 V, 5 V, and an adjustable setting. The device operates within a supply voltage range of 1 V to 7 V and consumes a typical quiescent current of 40 uA. It provides active high, active low, and open drain output types with a fixed reset delay time of 200 ms. The component offers 0.75% accuracy and includes power fail detection capabilities. It is housed in an MSOP-8 surface-mount package and functions without manual reset or watchdog timer features.

Supervisors Feature Summary

• Provides simultaneous monitoring of three distinct voltage rails including fixed and adjustable thresholds
• Offers flexible output configurations with active high, active low, and open drain options
• Integrates power fail detection for enhanced system reliability
• Operates with low quiescent current suitable for battery-powered applications

Supervisors Applications

• Microprocessor power supply supervision
• Multi-rail voltage monitoring systems
• Battery backup switching circuits
• Industrial control board protection

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the manufacturer part number matches exactly as Analog Devices Inc. produces this series. Check RoHS compliance status through official documentation before integration. Ensure the operating temperature range meets your environmental requirements. Validate pinout compatibility with your PCB layout design.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous supervision within a compact footprint. Consider the adjustable threshold option if custom voltage levels are needed alongside standard 3.3 V and 5 V rails. Evaluate the 200 ms reset delay against your system startup timing requirements. Compare the 40 uA quiescent current against power budget constraints for portable devices.

Supervisors Part Context

This part belongs to the LTC1326 series of supervisory circuits from Analog Devices. It shares the MSOP-8 package form factor with other components in the family but differs in internal threshold configurations. The series is designed for general-purpose voltage monitoring in embedded systems where space and power efficiency are critical constraints.
