The LM95221CIMMX is a precision, dual remote diode temperature sensor designed by Texas Instruments to offer extensive monitoring capabilities for complex systems. This high-performance component is suitable for a wide range of applications, including desktop and notebook computers, industrial and medical equipment, and embedded systems. It is engineered to provide accurate temperature readings by measuring the temperature of two remote diode-connected transistors while also measuring its own die temperature.

Key Features

• High Accuracy: The LM95221CIMMX offers ±1°C accuracy for external diode temperatures and ±2°C for its own temperature reading, ensuring precise thermal management.
• Dual Remote Diode Inputs: It can monitor two temperature zones, allowing for simultaneous tracking of multiple critical points in a system.
• Programmable Offset: Users can program an offset for each diode input, providing flexibility to correct for any diode non-idealities.
• Digital Output: Temperature readings are provided via a two-wire SMBus (System Management Bus) interface that supports the I²C protocol for easy integration into existing systems.
• Wide Temperature Range: The sensor operates over a temperature range of -40°C to +125°C, covering the needs of most environmental conditions.
• Supply Voltage: It is powered by a supply voltage in the range of 3.0V to 3.6V, making it compatible with most system power rails.
