Description and Introduction

±1°C, SMBus-Compatible Remote/Local Temperature Sensors with Overtemperature Alarms The MAX6657MSA+ is a temperature sensor and fan-speed controller manufactured by Maxim Integrated.  

### **Specifications:**  
- **Supply Voltage:** 3V to 5.5V  
- **Temperature Measurement Range:** -55°C to +125°C  
- **Accuracy:** ±1°C (from +60°C to +100°C)  
- **Fan Control:** Supports up to 4 fans with PWM or linear control  
- **Interface:** I²C/SMBus-compatible  
- **Resolution:** 0.125°C (temperature), 0.5% (fan speed)  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
The MAX6657MSA+ integrates a temperature sensor and fan controller, enabling precise thermal management in systems such as servers, PCs, and industrial equipment. It monitors temperature and adjusts fan speed to optimize cooling while minimizing noise.  

### **Features:**  
- **Automatic Fan Speed Control:** Adjusts fan speed based on temperature readings.  
- **Programmable Temperature Thresholds:** Allows user-defined limits for fan control.  
- **Multiple Fan Support:** Controls up to four fans.  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **Fault Detection:** Monitors fan operation for faults (e.g., stalled fan).  
- **I²C/SMBus Interface:** Enables communication with a host microcontroller.
