LTC2911IDDB-3#TRMPBF

Supervisors Overview

The LTC2911IDDB-3#TRMPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring multiple voltage rails in embedded systems. It features three independent voltage monitor channels housed in an 8-lead DFN package. The device provides open-drain reset outputs with a fixed 200 ms reset delay time to ensure system stability during power transitions. It operates within a supply voltage range of up to 6.5 V and supports threshold voltages of 2.5 V, 3.3 V, and adjustable levels. The component functions reliably across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides simultaneous supervision of three distinct input voltage rails
• Generates active-low reset signals via open-drain output configuration
• Ensures stable power-up sequencing through a fixed 200 ms reset delay timer

Supervisors Applications

• Multi-rail power management in industrial control systems
• Voltage supervision for microprocessor and FPGA boards
• Embedded system protection in automotive electronics

Supervisors Procurement Notes

Verify the specific suffix 'IDDB-3' against official Analog Devices documentation to confirm the exact threshold configurations and package type. Ensure compatibility with your board's thermal requirements and voltage levels before integration. Confirm RoHS compliance status directly from the manufacturer datasheet.

Supervisors Selection Notes

Select this component when a design requires monitoring three separate voltage lines using a single integrated supervisor. The open-drain output allows flexible interfacing with various logic families. Consider the fixed 200 ms delay as a constraint for fast-power-cycle applications where shorter delays are required.

Supervisors Part Context

This part belongs to the LTC2911 family of multi-channel voltage supervisors. It shares functional similarities with other members like the LTC2911ITS8 variants but differs in package style and specific threshold settings. The DFN package offers a compact footprint suitable for space-constrained PCB layouts compared to larger SOIC options.

Supervisors Replacement Considerations

Direct substitutes include other LTC2911 variants such as LTC2911HTS8-2#TRMPBF or LTC2911ITS8-1#TRMPBF, provided the pinout and threshold specifications match the original design requirements.
