LTC2908ITS8-B1#TRM

Supervisors Overview

The LTC2908ITS8-B1#TRM is a precision six-input supply monitor manufactured by Analog Devices Inc. It operates within a CMOS package and supports adjustable voltage supervision across six channels, with threshold ranges including 0.5V, 1.4V, 1.6V, 2.3V, and 3V. Designed for compact multi-supply monitoring solutions, it integrates supervisory circuitry in an SOT-23-8 surface-mount package. The component is classified under Supervisory Circuits and PMIC - Power Management ICs, offering precise monitoring for systems requiring multiple voltage rails.

Supervisors Feature Summary

• Provides simultaneous supervision for up to six independent power supply inputs
• Features adjustable voltage thresholds for flexible configuration across various rail voltages
• Delivers precise monitoring capabilities within a compact surface-mount footprint

Supervisors Applications

• Systems requiring precise and compact monitoring of multiple supply voltages
• Multi-rail power management architectures needing integrated supervision
• Embedded designs utilizing 12V, 3.3V, 2.5V, 1.8V, 1.5V, or 1.2V rails

Supervisors Procurement Notes

Verify the specific suffix B1 against the target design requirements to ensure correct threshold configurations. Confirm that the ITS8 package variant matches the PCB layout constraints. Check current lifecycle status as some listings indicate obsolete status for related variants. Ensure compatibility with existing firmware logic if digital outputs are utilized. Validate thermal performance within the SOT-23-8 package for the intended operating environment.

Supervisors Selection Notes

Select this component when a single device must monitor six distinct voltage rails without external comparators. The adjustable nature allows customization for non-standard voltage levels. Consider the SOT-23-8 package size for space-constrained applications. Evaluate the need for precise supervision accuracy over simpler threshold detectors. Ensure the system architecture can accommodate the specific input channel mapping defined by the B1 suffix.

Supervisors Part Context

This part belongs to the LTC2908 family of precision six-input supply monitors from Analog Devices. It shares functional similarities with variants like LTC2908CTS8-B1 and LTC2908IDDB-A1, differing primarily in package type and specific threshold settings. The family addresses the need for consolidated power monitoring in complex electronic systems, reducing component count compared to discrete solutions.

Supervisors Replacement Considerations

Public confirmed substitute part numbers include LTC2908CTS8-B1#TRPBF and LTC2908ITS8-B1#TRMPBF. Verify pinout compatibility and threshold specifications before substitution. Note that lifecycle status may vary between distributors; check for obsolescence warnings on similar model numbers.
