Description and Introduction

?2?C Remote and Local Temperature Sensor with TruTherm Technology and SMBus Interface 8-VSSOP -40 to 125 The LM95245CIMM is a digital temperature sensor manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Manufacturer:** National Semiconductor (NS)  
- **Part Number:** LM95245CIMM  
- **Package:** 8-pin VSSOP (Mini Small Outline Package)  
- **Interface Type:** SMBus (System Management Bus) compatible  
- **Temperature Range:**  
  - Local Sensor: -40°C to +125°C  
  - Remote Sensor (Diode): -64°C to +191°C  
- **Accuracy:**  
  - ±1°C (Local Sensor)  
  - ±1°C (Remote Diode Sensor, 60°C to 100°C)  
- **Resolution:** 0.125°C (9-bit for local, 11-bit for remote)  
- **Supply Voltage:** 3.0V to 3.6V  
- **Current Consumption:** 1.1mA (typical)  

### **Descriptions and Features:**  
- Monitors **local** (on-chip) and **remote** (external diode-connected transistor) temperatures.  
- Supports **two remote temperature channels** (ideal for multi-processor systems).  
- Programmable **temperature alert thresholds** with interrupt functionality.  
- **Auto-shutdown** mode for reduced power consumption.  
- **SMBus 2.0-compatible** interface with timeout feature.  
- **Beta compensation** for accurate remote diode temperature readings.  
- **Programmable conversion rate** (0.0625 Hz to 8 Hz).  
- **Thermal watchdog** function for system protection.  

This sensor is commonly used in **PCs, servers, and embedded systems** for thermal management.
