Description and Introduction

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

### **Specifications:**  
- **Temperature Range:** -55°C to +125°C  
- **Accuracy:** ±1°C (from +60°C to +100°C)  
- **Supply Voltage:** 3.0V to 5.5V  
- **Current Consumption:** 200µA (typical)  
- **Output:** PWM fan-speed control  
- **Package:** 8-pin TDFN (3mm x 3mm)  
- **Interface:** SMBus/I²C-compatible  

### **Descriptions and Features:**  
- Monitors the temperature of a remote thermal diode (e.g., CPU diode) and its own internal temperature.  
- Provides automatic fan-speed control based on temperature readings.  
- Programmable temperature thresholds with hysteresis.  
- Supports SMBus alert function for overtemperature conditions.  
- Includes a 2-wire serial interface for configuration and data readback.  
- Low-power operation suitable for battery-powered applications.  
- Integrated fault detection for open/short conditions in the remote sensor.  

This device is commonly used in computing and industrial applications for thermal management.
