LM63CIMA/NOPB

Thermal Management Overview

The LM63CIMA/NOPB is a board-mount temperature sensor manufactured by Texas Instruments. It features digital output via a 2-Wire SMBus interface and supports both local and remote sensing configurations. The device operates within a supply voltage range of 3 V to 3.6 V. It provides an accuracy of +/- 1 C across a temperature range of 0 C to +125 C. The component utilizes an 8-SOIC package and offers 10-bit resolution without a shutdown function.

Thermal Management Feature Summary

• Supports simultaneous local and remote temperature monitoring using internal and external sensors
• Provides digital data output through a standard 2-Wire SMBus compatible interface
• Integrates fan control capabilities alongside temperature monitoring functions

Thermal Management Applications

• Fan control systems requiring precise thermal management
• Temperature monitoring in electronic equipment
• Systems utilizing SMBus communication protocols for sensor data acquisition

Thermal Management Procurement Notes

Verify the specific suffix NOPB indicates lead-free compliance and RoHS status. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Ensure the SMBbus interface voltage levels are compatible with your system logic. Check for obsolescence notices as some variants may be marked not recommended for new designs.

Thermal Management Selection Notes

Select this component when dual-zone temperature sensing is required on a single chip. The integrated remote diode capability allows for accurate measurement at distant points. The SMBus interface simplifies connectivity compared to parallel or analog outputs. Verify that the 10-bit resolution meets your application's precision needs.

Thermal Management Part Context

This part belongs to the LM63 series of temperature sensors from Texas Instruments. The series includes variants with different accuracies and packaging options. The LM63CIMAX/NOPB is a tape-and-reel version of this component. Both parts share identical electrical specifications and functionality.

Thermal Management Replacement Considerations

LM63DIMA/NOPB is listed as a parameter equivalent alternative. LM63CIMA is the non-NOPB predecessor, though it may be obsolete. ADM1032ARZ-REEL is cited as a substitute option.
