LTC2911HDDB-3#TRMPBF

Supervisors Overview

The LTC2911HDDB-3#TRMPBF is a precision triple voltage monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.7V to 6.5V and features three independent monitoring channels with thresholds of 2.5V, 3.3V, and an adjustable setting. The device utilizes an open-drain output configuration and provides a fixed reset delay time of 200ms. It is housed in an 8-pin DFN package designed for surface-mount applications.

Supervisors Feature Summary

• Provides simultaneous supervision of three distinct voltage rails using dedicated input pins
• Features an adjustable threshold channel allowing customization for specific system requirements
• Delivers a standardized reset signal via an open-drain output interface

Supervisors Applications

• Multi-rail power sequencing in embedded systems
• Voltage supervision for microprocessor and FPGA core supplies
• Industrial control board power integrity monitoring

Supervisors Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm pinout and threshold specifications. Confirm RoHS compliance status and lead times directly with authorized distributors as availability fluctuates. Ensure the selected package variant matches the PCB footprint design constraints.

Supervisors Selection Notes

Select this component when precise monitoring of three separate voltage domains is required without external comparator circuitry. The adjustable threshold offers flexibility for non-standard rail voltages. Verify that the open-drain output capability aligns with the downstream logic level requirements of the target processor or controller.

Supervisors Part Context

This part belongs to the LTC2911 family of precision supervisors. It shares functional similarities with other multi-channel monitors but is distinguished by its specific combination of fixed and adjustable thresholds. The DFN package offers a compact solution for space-constrained designs requiring high accuracy.
