LTC2911CTS8-2

Supervisors Overview

The LTC2911CTS8-2 is a low-power, high-accuracy triple supply monitor manufactured by Analog Devices Inc. It features a power-fail comparator and supports reset timeout selection via an external capacitor. The device operates within a maximum supply voltage of 6.5 V and provides open-drain outputs. It monitors three input channels with threshold voltages including 2.5 V, 3.3 V, and adjustable levels. The component includes a fixed reset delay time of 200 ms and is housed in an SOT-23-8 surface-mount package.

Supervisors Feature Summary

• Triple supply monitoring capability for multiple voltage rails
• Integrated power-fail comparator function
• Configurable reset timeout using external capacitance
• Open-drain output configuration

Supervisors Applications

• Multi-rail power system supervision
• Embedded systems requiring voltage integrity checks
• Industrial control units with multiple power domains

Supervisors Procurement Notes

Verify availability status as the part may be subject to limited supply or factory special order conditions. Confirm RoHS compliance details and specific manufacturing lot dates during acquisition. Ensure compatibility with existing PCB footprint designs utilizing the SOT-23-8 package before finalizing procurement plans.

Supervisors Selection Notes

Select this component when simultaneous monitoring of three distinct voltage levels is required alongside power-fail signaling. The adjustable threshold options allow flexibility for various standard voltage rails. Consider the 200 ms fixed reset delay and open-drain output characteristics when designing downstream logic interfaces.

Supervisors Part Context

This part belongs to the LTC2911 series of supervisory circuits designed for precision voltage monitoring. It serves as a specialized PMIC solution for ensuring system stability by detecting under-voltage and over-voltage conditions across multiple power lines in compact electronic assemblies.

Supervisors Replacement Considerations

Consult official Analog Devices documentation for verified substitute part numbers. Cross-referencing with similar triple-supervisor ICs requires careful evaluation of pinout compatibility and electrical parameter alignment.
