Description and Introduction

9-Bit/12-Bit Temperature Sensors with I The MAX6625 is a temperature sensor and fan-speed controller manufactured by Maxim Integrated. Below 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 (from +60°C to +100°C)  
- **Fan Control Output:** PWM (Pulse-Width Modulation)  
- **Communication Interface:** I²C/SMBus-compatible  
- **Operating Current:** 1mA (typical)  
- **Package Types:** 8-pin SO, 8-pin µMAX  

### **Descriptions:**  
The MAX6625 integrates a temperature sensor and fan-speed controller in a single chip. It measures the temperature of a remote diode-connected transistor (e.g., CPU diode) or its own internal sensor and adjusts fan speed via PWM output to maintain optimal cooling.  

### **Features:**  
- **Remote and Local Temperature Sensing:** Supports external diode (CPU) and internal sensor.  
- **Programmable Fan Control:** Adjusts fan speed based on temperature thresholds.  
- **Automatic Fan Speed Adjustment:** Uses PWM to regulate fan speed dynamically.  
- **User-Configurable Registers:** Allows setting temperature thresholds and hysteresis.  
- **I²C/SMBus Interface:** Enables communication with a host microcontroller.  
- **Over-Temperature Alert:** Provides an interrupt output for critical temperature conditions.  
- **Low Power Consumption:** Suitable for battery-powered or energy-efficient systems.  

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