Introducing the LM95231BIMMX: Precision Dual Remote Diode Temperature Sensor

The LM95231BIMMX is a highly accurate, dual remote diode temperature sensor designed by Texas Instruments to meet the needs of complex thermal management systems. This precision sensor is particularly suitable for applications in the computer, industrial, and telecommunications sectors where reliable temperature monitoring is critical for system performance and safety.

With its ability to measure the temperature of two remote diode-connected transistors as well as its own die temperature, the LM95231BIMMX offers versatility and high performance. The remote diode temperature can be that of a CPU, GPU, or any other semiconductor device with a diode junction. The precision of this sensor ensures that temperature readings are accurate to within ±1°C, providing the data necessary for maintaining optimal operating conditions and protecting sensitive components from overheating.

The LM95231BIMMX supports a wide range of diode bias currents and has programmable digital filter options for remote temperature channels, allowing users to customize the sensor to their specific needs. The digital output of temperature readings is provided via an I²C/SMBus compatible interface, which supports the System Management Bus (SMBus) Time-out protocol for enhanced safety and reliability.

Key features of the LM95231BIMMX include:

• High accuracy and resolution: ±1°C accuracy for external diode temperatures and ±3°C for internal diode.
• Support for two remote temperature diodes and one local temperature diode.
• Programmable temperature conversion rate for dynamic thermal management.
• TruTherm™ technology, enabling accurate temperature measurements of modern, high-performance integrated circuits with beta compensation.
• Low supply current, ideal for power-sensitive applications.
• Small form factor: Provided in an 8-pin VSSOP package.

This sensor is available in a surface-mount package, the VSSOP-8, under the part number LM95231BIMMX, which is convenient for automated assembly processes and suitable for space-constrained applications. Texas Instruments' dedication to quality and performance makes the LM95231BIMMX a reliable choice for advanced temperature monitoring solutions.

Whether you're designing a sophisticated server, a high-performance gaming system, or a temperature-sensitive industrial application, the LM95231BIMMX from Texas Instruments stands as a top-tier choice for your temperature sensing needs.
