Description and Introduction

2-Channel Temperature Monitor with Dual Automatic PWM Fan-Speed Controller The MAX6640AEE+ is a temperature sensor and fan controller manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Package:** 16-QSOP  
- **Operating Voltage Range:** 3V to 5.5V  
- **Temperature Measurement Range:** -40°C to +125°C  
- **Accuracy:** ±1°C (typical) from +60°C to +100°C  
- **Interface:** SMBus/I²C-compatible  
- **Fan Control Output:** PWM (Pulse Width Modulation)  
- **Resolution:** 0.125°C (temperature measurement)  
- **Supply Current:** 350µA (typical)  

### **Descriptions:**  
The MAX6640AEE+ is a high-accuracy temperature sensor and fan controller designed for monitoring and managing system temperatures in electronic devices. It integrates a remote temperature sensor (for external diode sensing) and an on-chip temperature sensor. The device communicates via an SMBus/I²C interface and provides PWM fan control based on temperature readings.  

### **Features:**  
- **Dual Temperature Sensing:** Measures both local (on-chip) and remote (external diode) temperatures.  
- **Programmable Fan Control:** Adjusts fan speed via PWM output based on temperature thresholds.  
- **SMBus/I²C Interface:** Allows communication with a host controller.  
- **High Accuracy:** ±1°C typical accuracy in critical temperature ranges.  
- **Low Power Consumption:** Operates with minimal supply current.  
- **Wide Operating Range:** Supports temperatures from -40°C to +125°C.  
- **Small Form Factor:** Available in a 16-QSOP package for space-constrained applications.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
