Description and Introduction

Digital Temperature Sensor and Thermal Watchdog with Two-Wire Interface The LM75CIM-3 is a digital temperature sensor and thermal watchdog manufactured by National Semiconductor (NS). Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** National Semiconductor (NS)  
- **Package:** SOIC-8  
- **Operating Voltage Range:** 2.8V to 5.5V  
- **Temperature Range:** -55°C to +125°C  
- **Accuracy:** ±2°C (from -25°C to +100°C)  
- **Resolution:** 9 to 12 bits (programmable)  
- **Interface:** I²C-compatible (up to 400kHz)  
- **Power Consumption:** Low power (typ. 250µA in operation, 3.5µA in shutdown)  
- **Output:** Overtemperature shutdown with programmable threshold and hysteresis  

### **Descriptions:**  
The LM75CIM-3 is a digital temperature sensor with an I²C interface, designed for system thermal management. It provides accurate temperature readings and includes an overtemperature alarm output (OS) that can be used as an interrupt or comparator.  

### **Features:**  
- **Digital Temperature Sensing:** Converts temperature to a digital value with 0.125°C resolution (12-bit mode).  
- **Programmable Threshold & Hysteresis:** Allows user-defined overtemperature limits.  
- **Thermal Alarm Output (OS):** Active-low output for overtemperature detection.  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **Small Form Factor:** SOIC-8 package for space-constrained designs.  
- **I²C Bus Interface:** Supports standard (100kHz) and fast (400kHz) modes.  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and application notes, refer to the official documentation.
