Product Overview

The LM95245CIM/NOPB is a precision temperature sensor from Texas Instruments, designed to monitor the temperature of computer motherboards, communication equipment, and other embedded systems. This high-accuracy sensor is capable of measuring both its own temperature and the temperature of a remote diode, which can be a discrete transistor or a diode-connected transistor typically found in CPUs, GPUs, or other ICs.

Key Features

• Dual Temperature Sensing: The LM95245CIM/NOPB can measure both local and remote temperatures with high precision. The remote temperature channel has a range of -40°C to +125°C, while the local temperature channel has a range of 0°C to +85°C.
• Accuracy: It offers excellent accuracy, with ±1°C accuracy for remote diode temperatures and ±2°C for local temperatures over the entire temperature range.
• Interface: The device communicates over a 2-wire SMBus 2.0 compatible interface, which allows for easy integration into most system designs.
• Programmable Resolution: The LM95245CIM/NOPB's conversion resolution is programmable for both the local and remote channels, allowing for adjustments between 9 and 12 bits to balance between conversion speed and resolution.
• TruTherm Technology: Incorporating TruTherm technology, the sensor is capable of providing more accurate readings by compensating for non-idealities of the external diode.

Applications

This temperature sensor is ideal for a variety of applications that require precise temperature monitoring. It is particularly suited for:

• Desktop and Notebook Computers
• Servers
• Telecommunication Equipment
• Industrial and Medical Equipment
