Description and Introduction

8V CMOS Switched-Capacitor Voltage Converter The MAX665CPA is a temperature sensor and fan controller manufactured by Maxim Integrated (now part of Analog Devices). Below are its factual specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Operating Voltage:** 3V to 5.5V  
- **Temperature Measurement Range:** -55°C to +125°C  
- **Accuracy:** ±1°C (at +25°C)  
- **Temperature Resolution:** 1°C  
- **Fan Speed Control:** PWM (Pulse Width Modulation) output  
- **Fan Speed Monitoring:** Tachometer input for RPM measurement  
- **Interface:** I²C/SMBus compatible  
- **Operating Current:** 1mA (typical)  

### **Descriptions:**
The MAX665CPA is a precision temperature sensor with an integrated fan controller. It monitors system temperature and adjusts fan speed via PWM to maintain optimal cooling while minimizing noise. It also provides fan speed monitoring through a tachometer input. The device communicates via I²C/SMBus, making it suitable for embedded thermal management applications.

### **Features:**
- Integrated temperature sensor and fan controller  
- Supports PWM fan speed control  
- Fan speed monitoring via tachometer input  
- I²C/SMBus interface for communication  
- Wide operating voltage range (3V to 5.5V)  
- High accuracy (±1°C at +25°C)  
- Extended temperature measurement range (-55°C to +125°C)  
- Low power consumption (1mA typical)  

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