Description and Introduction

Digital Temperature Sensor and Thermal Watchdog with Two-Wire Interface The LM75BIM5 is a digital temperature sensor and thermal watchdog manufactured by NXP Semiconductors (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Temperature Range:** -55°C to +125°C  
- **Accuracy:** ±2°C (max) from -25°C to +100°C  
- **Resolution:** 0.125°C (9 to 12-bit selectable)  
- **Supply Voltage:** 2.8V to 5.5V  
- **Interface:** I²C-bus compatible (up to 400 kHz)  
- **Package:** SOT-23-5 (LM75BIM5)  
- **Shutdown Current:** < 3.5 µA  
- **Operating Current:** < 500 µA (typical)  
- **Programmable Hysteresis & Overtemperature Shutdown**  
- **Address Pins:** Three selectable addresses (up to 8 devices on the same bus)  

### **Descriptions:**  
The LM75BIM5 is a high-precision digital temperature sensor with an I²C interface. It provides temperature readings in a digital format, eliminating the need for external calibration. The sensor includes an overtemperature detection output (OS) that can function as an interrupt or comparator.  

### **Features:**  
- **Digital Output:** Eliminates external signal conditioning  
- **Programmable Threshold & Hysteresis:** Configurable via I²C  
- **Thermal Alarm Output (OS):** Can trigger system shutdown  
- **Low Power Consumption:** Suitable for battery-powered applications  
- **Small Form Factor:** SOT-23-5 package for space-constrained designs  
- **Wide Operating Voltage:** Compatible with 3.3V and 5V systems  

This sensor is commonly used in system thermal management, industrial controls, and consumer electronics.
