LTC2911CTS8-1#TRPBF

Supervisors Overview

The LTC2911CTS8-1#TRPBF is a low-power, high-accuracy triple supply monitor manufactured by Analog Devices Inc. It integrates three independent voltage supervisors and a power-fail comparator within an 8-pin TSOT-23 package. The device monitors fixed thresholds of 3.086V and 4.675V, alongside one adjustable channel. It features a push-pull/totem pole reset output with active-low logic and selectable reset timeout durations via an external capacitor. Operating from -40°C to +85°C, it draws only 10µA of quiescent current.

Supervisors Feature Summary

• Integrates three precision voltage monitoring channels with dedicated power-fail comparison capabilities
• Provides configurable reset timeout intervals through external capacitor selection
• Delivers active-low reset signals using a push-pull or totem pole output stage

Supervisors Applications

• Multi-rail power supply supervision in embedded systems
• Processor and FPGA board-level voltage monitoring
• Industrial control units requiring redundant power validation

Supervisors Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm pinout compatibility and electrical characteristics. Ensure the selected variant matches the required threshold voltages and output drive configuration for the target application design.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple voltage rails is required within a compact footprint. Consider the adjustable threshold capability for custom voltage levels and verify that the 10µA quiescent current aligns with system power budget constraints.

Supervisors Part Context

This part belongs to the LTC2911 series of supervisory circuits designed for portable and battery-operated equipment. The family offers various threshold combinations and package options to support diverse multi-voltage system architectures while maintaining high accuracy and low power consumption standards.

Supervisors Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any alternative maintains identical threshold values, output polarity, and package dimensions to guarantee mechanical and electrical compatibility without redesigning the PCB layout.
