LTC2911ITS8-5#TRMPBF

Supervisors Overview

The LTC2911ITS8-5#TRMPBF is a precision triple power supply monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.0V to 6.0V and draws a typical quiescent current of 10µA. The device features three independent voltage monitoring channels with fixed thresholds at 3.086V, 4.675V, and an adjustable threshold. It provides a push-pull active-low reset output with an adjustable timeout period ranging from 1ms to 10s. The component is housed in an 8-lead TSOT-23 package and supports an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides precise monitoring for three distinct power rails simultaneously
• Features an adjustable reset timeout timer for flexible system sequencing
• Includes a dedicated power-fail comparator for early warning detection

Supervisors Applications

• Portable battery-powered equipment requiring multi-voltage supervision
• Embedded systems needing reliable power-fail signaling
• Industrial control units with strict reset timing requirements

Supervisors Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm threshold configurations. Confirm availability status as distribution channels may report limited stock or end-of-life conditions. Ensure the selected package variant matches the required PCB footprint and thermal management specifications for the target application environment.

Supervisors Selection Notes

Select this component when simultaneous supervision of three voltages is required in a compact form factor. The adjustable reset timeout allows customization for different processor startup times. Consider the low quiescent current for battery-operated designs. Verify that the fixed thresholds align with the monitored rail voltages or utilize the adjustable channel for custom levels.

Supervisors Part Context

This part belongs to the LTC2911 family of triple power supply monitors. The series is designed for applications requiring high accuracy and low power consumption. Variants within the family differ primarily in threshold values and package types, offering flexibility for various board space and voltage monitoring needs.

Supervisors Replacement Considerations

Consult official cross-reference data for verified substitutes. Ensure replacement parts maintain compatible pinouts, threshold accuracies, and reset logic polarity.
