Description and Introduction

Fan Controller and Remote Temperature Sensor with SMBus Serial Interface The MAX1669 is a temperature sensor and fan-speed controller manufactured by Maxim Integrated.  

### **Specifications:**  
- **Temperature Sensing:** Monitors up to 5 remote diode-connected transistors (e.g., CPU, GPU) and its own internal temperature.  
- **Fan Control:** Supports up to 2 fans with PWM or linear voltage control.  
- **Accuracy:** ±1°C (local temperature), ±3°C (remote diodes).  
- **Voltage Range:** 3V to 5.5V supply.  
- **Communication Interface:** SMBus/I²C-compatible interface for configuration and monitoring.  
- **Resolution:** 1°C (temperature readings).  
- **Programmable Alerts:** Overtemperature and undertemperature thresholds with interrupt capability.  

### **Descriptions:**  
The MAX1669 is designed for thermal management in computers and other electronics. It provides accurate temperature readings from multiple sources and adjusts fan speeds dynamically to maintain optimal cooling while minimizing noise.  

### **Features:**  
- Monitors up to 5 remote temperature sensors (diode-connected transistors).  
- Controls 2 fans via PWM or DC voltage.  
- Programmable fan-speed curves based on temperature.  
- SMBus/I²C interface for system communication.  
- Overtemperature/undertemperature alarms.  
- Low power consumption.  

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