Thermal Management datasheet and documents for LM81CIMT-3/NOPB

LM81CIMT-3/NOPB

Thermal Management Overview

The LM81CIMT-3/NOPB is a serial interface ACPI-compatible microprocessor system hardware monitor manufactured by Texas Instruments. It integrates a digital temperature sensor with 9 or 12-bit resolution, a six-channel 8-bit ADC, and an 8-bit DAC for fan speed control. The device operates within a supply voltage range of 2.8 V to 3.8 V and supports temperatures from -40°C to +125°C. It utilizes a 24-TSSOP package and communicates via a two-wire SMBus interface.

Thermal Management Feature Summary

Integrates internal and external temperature sensing capabilities with specified accuracy.
Provides hardware monitoring through multiple analog-to-digital conversion channels.
Supports active fan speed regulation using integrated digital-to-analog output.
Enables system management communication through standard serial bus protocols.

Thermal Management Applications

Thermal Management Procurement Notes

Verify the specific suffix and packaging configuration against current manufacturer documentation, as component availability and lifecycle status may vary. Confirm that the selected variant matches the required interface and pinout specifications for your design. Check for any recent updates to the datasheet regarding electrical characteristics or recommended operating conditions before finalizing procurement plans.

Thermal Management Selection Notes

Select this component when designing systems requiring integrated thermal and voltage supervision with serial connectivity. Ensure the application environment stays within the specified -40°C to +125°C operating range. Verify that the host controller supports the required SMBus protocol for proper data exchange. Consider the 24-TSSOP package constraints during PCB layout planning to ensure adequate thermal dissipation and signal integrity.

Thermal Management Part Context

This part belongs to the LM81 series of hardware monitors designed for complex digital systems. It serves as a centralized monitoring solution for critical system parameters. The device consolidates multiple sensing functions into a single integrated circuit, reducing component count and board space requirements compared to discrete solutions.

Thermal Management Replacement Considerations

Public confirmed substitute part numbers are not available in the provided reference material. Consult official Texas Instruments documentation for potential cross-reference options or newer generation replacements if this component is no longer recommended for new designs.
