Product Overview: Texas Instruments LM95245CIMMX

The LM95245CIMMX is a precision temperature sensor from Texas Instruments, designed for advanced thermal management and protection in various electronic applications. This high-accuracy digital temperature sensor is capable of monitoring both its own temperature and the temperature of an external diode-connected transistor, which can be a thermal diode in a CPU, GPU, or other ASICs.

Key Features

• Dual Temperature Sensing: The LM95245CIMMX can measure its own die temperature and the temperature of a remote diode with great accuracy. This dual sensing capability is essential for systems that require temperature monitoring of multiple components.
• High Accuracy: This sensor provides ±1°C accuracy for the remote diode temperature and ±2°C for its own local temperature, ensuring precise thermal monitoring.
• Programmable Resolution: The device offers programmable resolution for the remote temperature sensor from 0.0625°C to 0.0078°C, allowing for fine-tuning based on the specific needs of the application.
• Flexible Bus Interface: It communicates through an SMBus 2.0-compatible, two-wire interface, which is widely used in modern electronic systems for easy integration.
• Low Power Consumption: Designed for efficient operation, the LM95245CIMMX has a quiescent current of just 0.5mA (typical), making it suitable for power-sensitive applications.
• Small Form Factor: The device comes in a compact, 8-pin VSSOP package, which is ideal for space-constrained applications.
