LM87CIMT

Thermal Management Overview

The LM87CIMT is a hardware monitor integrated circuit manufactured by Texas Instruments. It features an internal and external sensor configuration with a two-wire serial interface compatible with I2C and SMBus protocols. The device operates within a supply voltage range of 2.8V to 3.8V and supports a functional temperature range from -40°C to +125°C. It utilizes a 24-TSSOP package with a width of 4.40mm. Typical local accuracy is ±3°C, while maximum remote accuracy is ±4°C. The topology includes delta-sigma ADC, comparator, fan speed counter, and register groups.

Thermal Management Feature Summary

• Supports both internal and external temperature sensing for comprehensive thermal monitoring.
• Provides digital output via standard two-wire serial communication interfaces.
• Integrates fan speed counting capabilities alongside system supervision functions.

Thermal Management Applications

• Server and workstation hardware monitoring
• Industrial control system thermal management
• Communication equipment temperature supervision

Thermal Management Procurement Notes

Verify the specific suffix against the manufacturer's current documentation to ensure compatibility with required interface standards and packaging options. Confirm that the 24-TSSOP footprint matches the target PCB design constraints. Ensure the operating voltage requirements align with the system power rails before integration into the final assembly.

Thermal Management Selection Notes

Select this component when dual-zone temperature monitoring is required using a serial interface. The device is suitable for applications needing precise local measurement with acceptable remote sensor accuracy. Consider the 24-pin form factor for space-constrained designs requiring multiple monitoring channels without complex parallel bus architectures.

Thermal Management Part Context

This part belongs to the LM87 family of hardware monitors designed for supervising critical system parameters. It serves as a dedicated solution for tracking thermal conditions in high-reliability electronics. The series is widely utilized in environments where continuous operational stability and accurate fault detection are mandatory for system integrity.

Thermal Management Replacement Considerations

Consult official substitution lists for variants such as LM87CIMTX/NOPB which share similar functionality but differ in tape-and-reel packaging. Verify pinout compatibility and software register mapping before swapping components to avoid redesign efforts.
