Description and Introduction

Dual Remote/Local Temperature Sensors and Four-Channel Voltage Monitors The MAX6655MEE+ is a temperature sensor and fan-speed controller manufactured by Maxim Integrated.  

### **Specifications:**  
- **Supply Voltage Range:** 3V to 5.5V  
- **Temperature Measurement Range:** -55°C to +125°C  
- **Accuracy:** ±1°C (0°C to +85°C)  
- **Fan Control:** Supports PWM and TACH monitoring  
- **Interface:** I²C/SMBus-compatible  
- **Resolution:** 0.125°C (digital temperature reading)  
- **Package:** 16-pin QSOP  

### **Descriptions:**  
The MAX6655MEE+ integrates a temperature sensor and fan controller, allowing precise thermal management in electronic systems. It measures its own temperature as well as an external diode-connected transistor (e.g., CPU diode). It supports automatic or software-controlled fan-speed adjustment based on temperature readings.  

### **Features:**  
- **Dual Temperature Monitoring:** Measures internal and external diode temperatures.  
- **Programmable Fan Control:** Adjusts fan speed via PWM or voltage control.  
- **Tachometer Input:** Monitors fan speed for fault detection.  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **Alarm Outputs:** Signals overtemperature conditions.  
- **I²C/SMBus Interface:** Allows communication with a microcontroller.  

This device is commonly used in PCs, servers, and embedded systems for thermal regulation.
