Description and Introduction

±1°C, SMBus-Compatible Remote/Local Temperature Sensor with Overtemperature Alarm The MAX6642ATT98-T is a temperature sensor and fan-speed controller manufactured by Maxim Integrated.  

### **Specifications:**  
- **Temperature Range:** -40°C to +125°C  
- **Accuracy:** ±1°C (max) from +60°C to +100°C  
- **Supply Voltage Range:** 3V to 5.5V  
- **Current Consumption:** 200µA (typical)  
- **Output Type:** Digital (SMBus/I²C interface)  
- **Package:** 6-Pin TDFN (2mm x 2mm)  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
The MAX6642ATT98-T monitors the temperature of a remote thermal diode (e.g., CPU) and its own internal temperature. It provides fan-speed control based on the measured temperature, optimizing cooling efficiency while minimizing noise.  

### **Features:**  
- Dual temperature monitoring (remote and local)  
- Programmable fan-speed control  
- SMBus/I²C-compatible interface  
- High accuracy (±1°C max at critical ranges)  
- Low power consumption  
- Small footprint (TDFN package)  
- Automatic fan-speed adjustment for thermal management  

This device is commonly used in PCs, servers, and other systems requiring precise thermal monitoring and fan control.
