Description and Introduction

Dual Remote and Local Temperature Sensor with TruTherm Technology and SMBus, I2C Interface 8-VSSOP 0 to 85 The LM95221CIMM/NOPB is a digital temperature sensor with an integrated fan controller, manufactured by National Semiconductor (NSC).  

### **Specifications:**  
- **Manufacturer:** National Semiconductor (NSC)  
- **Package:** 8-Pin VSSOP (MSOP)  
- **Operating Voltage:** 3.0V to 3.6V  
- **Temperature Range:**  
  - Local Sensor: -40°C to +125°C  
  - Remote Sensor: -64°C to +191°C  
- **Accuracy:**  
  - Local Sensor: ±1.5°C (max) at +25°C  
  - Remote Sensor: ±1°C (max) at +70°C  
- **Resolution:** 0.125°C (local and remote)  
- **Interface:** SMBus 2.0 compliant  
- **Fan Control:** PWM output with programmable speed control  
- **Features:**  
  - Monitors two temperature zones (local and remote diode)  
  - Programmable temperature thresholds with ALERT output  
  - Supports automatic fan speed control  
  - Low power consumption  

### **Descriptions and Features:**  
- The LM95221CIMM/NOPB is designed for accurate temperature monitoring and fan control in computing and industrial applications.  
- It includes an on-chip local temperature sensor and supports an external thermal diode (e.g., CPU diode).  
- The device provides high-resolution temperature readings and programmable fan speed control via PWM.  
- It is compatible with SMBus communication for easy integration into digital systems.  
- The ALERT function allows for interrupt-based temperature monitoring.  
- Suitable for applications requiring precise thermal management, such as servers, desktops, and embedded systems.  

This information is strictly based on the manufacturer's datasheet.
