LTC2911CTS8-4#TRMPBF

Supervisors Overview

The LTC2911CTS8-4#TRMPBF is a precision triple supply monitor manufactured by Analog Devices Inc. It features three independent voltage monitoring channels with thresholds of 3.086V, 4.675V, and an adjustable setting. The device includes a power-fail comparator and operates within a temperature range of -40°C to 85°C. It consumes 10 µA of operating supply current and utilizes a TSOT-23-8 surface-mount package.

Supervisors Feature Summary

• Provides precise monitoring for three distinct supply voltages simultaneously
• Integrates a dedicated power-fail comparator for system status indication
• Offers selectable reset timeout functionality via external capacitor

Supervisors Applications

• Multi-rail embedded systems requiring simultaneous voltage supervision
• Industrial control units with mixed voltage logic levels
• Communication equipment needing reliable power-fail signaling

Supervisors Procurement Notes

Verify the specific suffix 'CTS8-4' against official Analog Devices documentation to confirm threshold values and package type. Ensure compatibility with existing PCB footprints for the TSOT-23-8 form factor. Cross-reference datasheet revision dates to validate electrical characteristics before integration into final designs.

Supervisors Selection Notes

Select this component when three-channel supervision is required in a compact footprint. The fixed thresholds suit applications with standard voltage rails, while the adjustable channel allows flexibility. Consider the 10 µA quiescent current for battery-sensitive designs. Verify that the push-pull output drive capability meets downstream load requirements.

Supervisors Part Context

This part belongs to the LTC2911 series of low-power, high-accuracy triple supply monitors. It is designed for applications requiring multiple voltage rails to be monitored concurrently. The series emphasizes precision and low power consumption, making it suitable for portable and industrial electronics where space and energy efficiency are critical constraints.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the Analog Devices portfolio that match the TSOT-23-8 package. Verify if other series members offer similar threshold configurations or if external resistor networks can replicate the fixed settings of the CTS8-4 variant.
