LTC2911ITS8-3#TRPBF

Supervisors Overview

The LTC2911ITS8-3#TRPBF is a precision triple supply monitor manufactured by Analog Devices Inc. It features an ultralow voltage reset capability, ensuring operation with VCC as low as 0.5V. The device simultaneously monitors three distinct inputs within a TSOT-23-8 package. One input provides a fixed threshold for 1.2V supplies, while the second and third inputs are adjustable via external resistive dividers to accommodate various system voltages. It integrates a power-fail comparator and offers selectable reset timeout durations.

Supervisors Feature Summary

• Simultaneous monitoring of three independent supply rails
• Ultralow voltage reset functionality down to 0.5V
• Integrated power-fail comparator for system status indication
• Configurable reset timeout using an external capacitor

Supervisors Applications

• Portable instrumentation systems requiring multi-rail supervision
• Industrial automation equipment with complex power architectures
• Embedded systems needing precise voltage threshold detection
• Battery-powered devices requiring low-voltage operation monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Request official datasheets and test reports to confirm compliance with RoHS standards. Ensure storage conditions meet moisture sensitivity level requirements prior to surface mount assembly. Cross-reference ordering suffixes carefully to match specific threshold configurations and packaging formats.

Supervisors Selection Notes

Select this component when simultaneous supervision of three voltage rails is required in space-constrained designs. The adjustable thresholds allow flexibility for non-standard supply voltages. Consider the external capacitor requirement for defining reset delays during timing-critical applications. Evaluate the power-fail comparator output against system interrupt capabilities.

Supervisors Part Context

This part belongs to the LTC2911 series of precision triple supply monitors. It shares the core architecture with variants like the LTC2911ITS8-1 and LTC2911ITS8-2, differing primarily in factory-set threshold configurations. The ITS8 suffix indicates the specific TSOT-23-8 thin package type suitable for high-density PCB layouts.

Supervisors Replacement Considerations

Direct substitutes include other LTC2911 variants such as LTC2911ITS8-1#TRMPBF or LTC2911ITS8-2#TRPBF, provided their fixed thresholds align with the design requirements. Verify pin compatibility and electrical specifications before substitution.
