The LM95221CIMM is a highly accurate, low-power, dual remote diode temperature sensor designed by Texas Instruments. This precision sensor is ideal for monitoring the temperature of two remote diode-connected transistors, which can be found in CPUs, GPUs, or other heat-generating semiconductor devices.

Key Features:

• Accuracy: The LM95221CIMM offers exceptional accuracy, with ±1°C accuracy for external diode temperatures from -40°C to +125°C.
• Dual Remote Diode Inputs: It can measure temperature from two diode inputs, which are typically the transistors in a CPU or GPU, allowing for comprehensive thermal management.
• Programmable Offset: An adjustable offset for non-ideal diodes enables fine-tuning of temperature measurements to account for diode variations.
• Low-Power Consumption: This device is optimized for power-sensitive applications, ensuring minimal impact on overall system power.
• SMBus Interface: The sensor communicates with the host controller via the SMBus (System Management Bus), making it easy to integrate into existing systems.
• TruTherm™ Technology: Texas Instruments' proprietary TruTherm™ technology allows the sensor to make precise measurements even with non-ideal diodes.

Applications:

The LM95221CIMM is suitable for a wide range of applications, including:

• Personal computers and servers
• Office electronics
• Industrial and medical equipment
• Networking and telecommunications

Package and Availability:

The sensor is housed in a small 8-pin VSSOP package, making it easy to incorporate into space-constrained designs. It is available for order directly from Texas Instruments or through authorized distributors. Designers can take advantage of the LM95221CIMM's features to enhance system reliability and performance by implementing effective thermal management strategies.
