Description and Introduction

1C / SMBus-Compatible Remote/Local Temperature Sensors with Overtemperature Alarms The MAX6659MEE is a temperature sensor and fan-speed controller manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Package:** 16-QSOP (0.154", 3.90mm Width)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Supply Voltage:** 3V to 5.5V  
- **Temperature Accuracy:** ±1°C (typical) from +60°C to +100°C  
- **Fan Control:** PWM (Pulse Width Modulation) output  
- **Interface:** SMBus/I²C-compatible  
- **Resolution:** 11-bit ADC for temperature sensing  
- **Fan Speed Monitoring:** Tachometer input for RPM measurement  

### **Descriptions:**  
The MAX6659MEE is a high-precision temperature sensor and fan controller designed for monitoring and regulating fan speeds in electronic systems. It integrates temperature sensing and fan-speed control in a single chip, making it suitable for applications requiring thermal management, such as computers, servers, and industrial equipment.  

### **Features:**  
- **Dual Temperature Monitoring:** Measures its own die temperature and an external diode (e.g., CPU diode).  
- **Programmable Fan Control:** Adjusts fan speed based on temperature thresholds.  
- **Automatic Fan Speed Control:** Uses PWM to optimize cooling while minimizing noise.  
- **SMBus/I²C Interface:** Allows communication with a host microcontroller.  
- **Alarm Output:** Provides overtemperature alerts.  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **Flexible Configuration:** User-programmable temperature thresholds and fan-speed curves.
