Description and Introduction

±1°C/±3°C Accurate Remote Diode Digital Temperature Sensor with Integrated Fan Control The LM63DIMAX is a digital temperature sensor with an integrated fan controller, manufactured by NS (National Semiconductor).  

### **Specifications:**  
- **Temperature Sensing Range:** -40°C to +125°C  
- **Accuracy:** ±1°C (typical) from +60°C to +100°C  
- **Resolution:** 1°C  
- **Supply Voltage:** 3.0V to 3.6V  
- **Interface:** SMBus (System Management Bus) compatible  
- **Programmable Fan Control:** Supports PWM (Pulse-Width Modulation) output for fan speed regulation  
- **Programmable Alert Function:** Overtemperature warning with interrupt capability  
- **Package Type:** 8-pin SOIC  

### **Descriptions and Features:**  
- Monitors the temperature of a remote diode-connected transistor (e.g., CPU diode)  
- Includes an on-chip diode for local temperature sensing  
- Fan speed control based on temperature readings  
- Supports automatic fan speed adjustment to minimize noise  
- Programmable hysteresis and fault detection  
- Low power consumption  

This device is commonly used in PC motherboards, servers, and other systems requiring thermal management.
