LTC1326IMS8-2.5#TRPBF

Supervisors Overview

The LTC1326IMS8-2.5#TRPBF is a precision triple supply monitor manufactured by Analog Devices Inc., designed for microprocessor applications. It features three independent voltage monitoring channels with fixed thresholds, including a specific 2.5V setting for the IMS8-2.5 variant. The device operates within a supply voltage range of 1V to 7V and offers an accuracy of 0.75%. It provides active high, active low, and open drain output options with a reset delay time of 200 ms. The component supports chip enable functionality and power failure detection while consuming only 40 uA of operating current. It is housed in an 8-pin MSOP package suitable for surface mount installation.

Supervisors Feature Summary

• Triple channel voltage supervision with configurable output polarities
• High accuracy threshold detection for reliable system monitoring
• Integrated power failure detection capability
• Low power consumption with chip enable control

Supervisors Applications

• Microprocessor system reset circuits
• Battery-powered device voltage supervision
• Industrial control board monitoring
• Embedded system power management

Supervisors Procurement Notes

Verify the exact suffix matching your design requirements, as the #TRPBF indicates tape and reel packaging which differs from tube variants. Confirm the specific threshold version (e.g., -2.5) aligns with your voltage rails. Check regional availability status as distribution may be restricted in certain areas. Ensure the MSOP-8 footprint matches your PCB layout constraints before finalizing procurement orders.

Supervisors Selection Notes

Select this component when precise multi-rail monitoring is required without manual reset intervention. The fixed threshold versions simplify design compared to adjustable counterparts. Consider the 200 ms reset delay for compatibility with target processor startup times. Evaluate the 0.75% accuracy against system tolerance requirements. The open drain option allows flexible logic level interfacing across different voltage domains.

Supervisors Part Context

This part belongs to the LTC1326 series of supervisory circuits from Analog Devices. It complements other PMIC components like the LTC3404 buck regulator in complete power management solutions. The IMS8-2.5 variant specifically targets applications requiring a 2.5V monitoring threshold alongside two other fixed voltages. It serves as a critical reliability component in systems where undervoltage conditions must trigger immediate resets.

Supervisors Replacement Considerations

Public confirmed substitutes include the LTC1326CMS8#PBF and LTC1326IMS8#TRPBF for general triple monitor needs. For fixed 2.5V threshold requirements, the LTC1326IMS8-2.5#PBF is the tube-packaged equivalent. Verify pinout compatibility and electrical specifications before substitution.
