LTC2911ITS8-4

Supervisors Overview

The LTC2911ITS8-4 is a precision triple-input voltage monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.5V to 36V and features a low quiescent current of 850nA. The device provides three independent monitoring channels with fixed thresholds, including specific settings for the -4 suffix variant. It utilizes a TSOT-23-8 surface-mount package and supports an operating temperature range from -40°C to +85°C. The output configuration includes a push-pull/totem pole reset signal that is active low, ensuring reliable system supervision in compact designs.

Supervisors Feature Summary

• Provides precise monitoring across three independent input channels
• Features a push-pull output stage for robust drive capability
• Operates with ultra-low quiescent current consumption
• Supports extended industrial temperature ranges

Supervisors Applications

• Portable electronic devices requiring multi-rail supervision
• Industrial control systems with multiple voltage domains
• Communication equipment needing reliable power-fail detection
• Battery-powered instruments with strict power constraints

Supervisors Procurement Notes

Verify the exact suffix designation when ordering, as variants like ITS8-1 differ in threshold configurations. Confirm availability status directly with authorized distributors, as stock levels fluctuate. Ensure the selected package matches the PCB footprint requirements. Check RoHS compliance documentation for regulatory adherence. Validate the operating temperature range against the specific environmental conditions of the target application before finalizing procurement.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous supervision within a limited space. The TSOT-23-8 package offers a compact solution for dense layouts. Consider the fixed threshold options if programmable inputs are unnecessary. Evaluate the push-pull output requirement versus open-drain alternatives based on downstream logic compatibility. Ensure the supply voltage range covers all monitored rail variations during transient events.

Supervisors Part Context

This part belongs to the LTC2911 series of supervisory circuits designed for precision monitoring applications. The series includes various packages and threshold combinations to suit different design needs. Analog Devices integrates these monitors into broader power management portfolios, emphasizing low power consumption and high accuracy for modern embedded systems.

Supervisors Replacement Considerations

Direct substitutes include other LTC2911 variants such as LTC2911ITS8-1#TRMPBF or LTC2911HTS8-1#TRMPBF, depending on required threshold values. Cross-reference pinouts and electrical characteristics carefully. Verify package compatibility for seamless integration without PCB redesign.
