LTC2911ITS8-2

Supervisors Overview

The LTC2911ITS8-2#TRMPBF is a multi-voltage supervisory circuit manufactured by Analog Devices Inc. It monitors three independent voltage inputs within a TSOT-23-8 package. The device features adjustable thresholds, with specific configurations including 3.086V and 4.675V fixed options alongside an adjustable channel. It provides a push-pull/totem pole output for reset signaling and supports selectable or adjustable reset timeout durations. Operating across a temperature range of -40°C to +85°C, it is designed for surface-mount installation.

Supervisors Feature Summary

• Monitors up to three independent voltage rails simultaneously
• Provides push-pull or totem pole reset output signal
• Features selectable or adjustable reset timeout duration
• Supports configurable threshold voltages including fixed and adjustable options

Supervisors Applications

• Multi-rail power supply supervision in embedded systems
• Voltage monitoring for portable electronic devices
• Industrial control system power integrity verification

Supervisors Procurement Notes

Verify the exact suffix configuration when ordering, as the LTS2911 series utilizes specific alphanumeric codes to denote threshold settings and package variations. Confirm availability status directly with authorized distributors, as stock levels fluctuate. Ensure the selected variant matches the required threshold voltages and output type for the target application design.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple voltage lines is required in a compact footprint. The push-pull output capability allows direct interfacing with various logic families without additional pull-up components. Consider the adjustable timeout feature if precise reset delay synchronization is necessary for the system startup sequence.

Supervisors Part Context

This part belongs to the LTC2911 family of supervisory circuits from Analog Devices. The family offers various pinout and threshold combinations to accommodate different multi-voltage monitoring requirements. The ITS8-2 designation specifically indicates the industrial temperature grade and the particular threshold configuration associated with the SOT-23-8 thin package variant.

Supervisors Replacement Considerations

Direct replacements must match the TSOT-23-8 package and support three-channel monitoring. Verify that alternative parts offer compatible push-pull outputs and similar threshold accuracy. Cross-reference datasheets to ensure equivalent reset timeout functionality and operating voltage ranges.
