LTC2911ITS8-5#TRPBF

Supervisors Overview

The LTC2911ITS8-5#TRPBF is a precision triple-input voltage supervisor manufactured by Analog Devices Inc. It monitors three independent supply rails with fixed thresholds of 3.086V, 4.675V, and an adjustable third channel. The device features a push-pull active-low reset output with selectable timeout durations. It operates within a supply voltage range of 1.2V to 5.5V and supports a power-fail comparator for early warning. Packaged in an 8-lead TSOT-23 surface-mount case, it ensures reliable system protection across industrial temperature ranges.

Supervisors Feature Summary

• Monitors three independent voltage inputs with high accuracy
• Provides active-low reset signal with configurable timing
• Integrates a dedicated power-fail comparator output

Supervisors Applications

• Embedded system power supervision
• Industrial control board monitoring
• Communication equipment voltage tracking

Supervisors Procurement Notes

Verify the specific suffix designation to confirm threshold configurations. The ITS8-5 variant indicates fixed thresholds on two channels and an adjustable third. Confirm package integrity and manufacturer authenticity through authorized distribution channels before integration into production designs.

Supervisors Selection Notes

Select this component when precise monitoring of multiple distinct voltage rails is required within a compact footprint. The adjustable third channel offers flexibility for non-standard voltages. Ensure the selected timeout configuration aligns with the target system's startup requirements and noise immunity needs.

Supervisors Part Context

This part belongs to the LTC2911 series of multi-channel supervisors. It shares the same functional architecture as other variants but differs in input threshold specifications. The TSOT-23-8 package allows for space-constrained PCB layouts while maintaining thermal performance suitable for dense electronic assemblies.

Supervisors FAQ

What is the function of the third input channel?

The third input channel features an adjustable threshold, allowing designers to monitor custom voltage levels using external resistors.

How does the power-fail comparator operate?

It provides an open-drain output that signals an impending fault condition before the main reset threshold is reached, enabling graceful shutdown procedures.
