Description and Introduction

Advanced Lithium-Ion Battery-Pack Protector The MAX1666XEEP+ is a temperature sensor and fan controller manufactured by Maxim Integrated. Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage Range:** 3V to 5.5V  
- **Temperature Measurement Range:** -55°C to +125°C  
- **Temperature Accuracy:** ±1°C (typical) from +60°C to +100°C  
- **Fan Control Output:** PWM (Pulse-Width Modulation)  
- **Number of Temperature Channels:** 2 (remote and local diode sensors)  
- **Interface:** SMBus/I²C-compatible  
- **Package:** 20-pin QSOP (Exposed Pad)  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
The MAX1666XEEP+ is a high-precision temperature sensor and fan controller designed for monitoring processor and system temperatures. It supports both remote diode sensing (for CPU/GPU) and local temperature measurement. The device provides PWM fan speed control based on temperature readings, ensuring efficient thermal management.  

### **Features:**  
- **Dual Temperature Monitoring:** Measures remote (CPU) and local (ambient) temperatures.  
- **Programmable Fan Control:** Adjusts fan speed via PWM output based on temperature thresholds.  
- **SMBus/I²C Interface:** Allows communication with a host microcontroller.  
- **High Accuracy:** ±1°C typical accuracy in critical ranges.  
- **Low Power Consumption:** Optimized for energy-efficient systems.  
- **Fault Detection:** Includes open/short-circuit detection for remote diode sensors.  
- **Programmable Alert Output:** Issues interrupts for overtemperature conditions.  

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