LTC2911IDDB-4#TRPBF

Supervisors Overview

The LTC2911IDDB-4#TRPBF is a precision triple power supply monitor manufactured by Analog Devices Inc. It features three independent voltage monitoring channels housed in an 8-pin DFN package. The device monitors two fixed thresholds at 3.086V and 1.122V, alongside one adjustable threshold channel. It operates with a low quiescent current of 10µA and supports a wide input voltage range. The component provides open-drain reset outputs and includes a programmable timeout function for reliable system supervision.

Supervisors Feature Summary

• Triple-channel voltage monitoring capability with two fixed thresholds and one adjustable threshold
• Low power consumption with 10µA typical operating current
• Open-drain reset output configuration for flexible logic interfacing
• Programmable reset timeout to prevent false triggering during power transitions

Supervisors Applications

• Portable equipment requiring multi-voltage supervision
• Battery-powered systems needing efficient power management
• Industrial control units with multiple power rails
• Communication infrastructure monitoring critical voltage levels

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the -I grade temperature range matches your operational environment requirements. Ensure the DFN-8 footprint aligns with your PCB layout constraints. Cross-reference the exact part number with manufacturer documentation to confirm availability status as distribution may vary.

Supervisors Selection Notes

Select this component when simultaneous monitoring of three distinct voltage rails is required. The fixed thresholds suit standard logic and battery levels, while the adjustable channel offers flexibility for custom references. Consider the open-drain output if level shifting or wired-OR configurations are necessary within the target circuit design.

Supervisors Part Context

This part belongs to the LTC2911 series of precision power supply supervisors. It is designed for applications requiring high accuracy and low power usage. The series typically includes variants with different fixed thresholds and packages, allowing designers to choose the optimal solution for specific voltage monitoring needs without compromising system reliability.

Supervisors Replacement Considerations

Direct substitutes include other parts from the LTC2911 family with compatible pinouts and similar threshold specifications. Verify that any replacement maintains the same open-drain output type and quiescent current characteristics to ensure circuit compatibility.
