LTC2995IUD#PBF

Thermal Management Overview

The LTC2995IUD#PBF is a high-accuracy temperature sensor and dual voltage monitor featuring open-drain alert outputs. It converts the temperature of an external diode or its own die to an analog output voltage while rejecting noise and series resistance errors. The device monitors two supply voltages against upper and lower limits set by resistive dividers, triggering alerts when thresholds are exceeded. It operates on a 2.25V to 5.5V supply with a quiescent current of 220μA and provides a 1.8V reference output for threshold programming.

Thermal Management Feature Summary

• Provides accurate temperature measurement using commonly available NPN/PNP transistors or built-in digital device diodes.
• Monitors two system voltages for undervoltage and overvoltage conditions with adjustable thresholds.
• Features series resistance cancellation to maintain accuracy in remote sensing applications.
• Generates open-drain logic alerts for temperature and voltage violations.

Thermal Management Applications

• Network servers
• Core and I/O voltage monitors
• Desktop and notebook computers
• Environmental monitoring

Thermal Management Procurement Notes

Verify the specific suffix 'IUD' corresponds to the industrial temperature range (-40°C to 85°C) and QFN package. Confirm RoHS compliance status via the manufacturer's official documentation before procurement. Ensure the ordering part number matches the exact grade required for your application environment.

Thermal Management Selection Notes

Select this component when simultaneous monitoring of multiple supply rails and precise temperature tracking is required. The integrated 1.8V reference simplifies external resistor divider design for threshold setting. Consider the 3mm x 3mm QFN package constraints for PCB layout and thermal management during selection.

Thermal Management Part Context

This part belongs to the Analog Devices LTC2995 family of supervisory circuits. It integrates a temperature converter and dual voltage supervisor into a single compact solution. The 'IUD' designation indicates the industrial temperature grade and the 20-lead plastic QFN package format.
