LTC2911HDDB-2#TRPBF

Supervisors Overview

The LTC2911HDDB-2#TRPBF is a multi-supply voltage monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.7V to 5.5V and features three independent monitoring channels with fixed thresholds at 4.386V, 2.940V, and 2.625V. The device provides an active-low reset output with a selectable timeout period of 140ms or 1.4s. It consumes a maximum quiescent current of 10µA and functions reliably across an industrial temperature range of -40°C to +125°C. The component is housed in an 8-pin DFN package.

Supervisors Feature Summary

• Provides simultaneous supervision of three distinct power rails using fixed internal threshold comparators
• Features a configurable reset delay allowing selection between fast and slow assertion times
• Delivers an active-low push-pull reset signal for direct microprocessor interface compatibility

Supervisors Applications

• Portable instrumentation requiring multiple voltage domains
• Industrial automation control systems
• Embedded computing platforms needing reliable power sequencing

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the manufacturer designation matches Analog Devices Inc. to ensure authenticity. Check RoHS compliance status against current regulatory requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when precise monitoring of three specific voltage levels is required without external resistor dividers. The fixed thresholds eliminate calibration needs compared to adjustable monitors. Ensure the operating supply voltage remains within the specified 1.7V to 5.5V range during all operational states.

Supervisors Part Context

This part belongs to the LTC2911 series of precision multi-supply voltage monitors. It shares functional similarities with other members like the LTC2912 but differs in channel count and threshold configurations. The series is designed for applications demanding high accuracy and low power consumption in compact surface-mount packages.

Supervisors Replacement Considerations

LTC2911HDDB-1#TRPBF offers identical functionality but with different fixed voltage thresholds. Verify that the alternative thresholds align with the target system's power rail specifications before substitution.
