Description and Introduction

±1°C/±3°C Accurate Remote Diode Digital Temperature Sensor with Integrated Fan Control The LM63DIMA is a digital temperature sensor with an integrated fan controller, manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Supply Voltage:** 3.0V to 3.6V  
- **Temperature Measurement Range:** -40°C to +125°C  
- **Accuracy:** ±1°C (max) from +60°C to +100°C  
- **Resolution:** 0.125°C  
- **Interface:** SMBus/I²C compatible  
- **Programmable Fan Control:** Supports PWM or linear fan speed control  
- **Programmable Alert Function:** Thermal interrupt output  
- **Package:** 8-pin SOIC  

### **Descriptions and Features:**  
- **Digital Temperature Sensing:** Monitors remote diode temperature (e.g., CPU diode) and local temperature.  
- **Fan Speed Control:** Adjusts fan speed based on temperature readings to optimize cooling.  
- **Programmable Hysteresis:** Helps reduce fan noise by preventing rapid speed changes.  
- **SMBus/I²C Interface:** Allows communication with a host controller.  
- **Thermal Alert:** Provides an interrupt signal if temperature exceeds a set threshold.  
- **Low Power Consumption:** Suitable for battery-powered or energy-efficient applications.  

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