Description and Introduction

12-Bit Plus Sign Temperature Sensors with SMBus/I²C-Compatible Serial Interface The MAX6635MSA+ is a temperature sensor and fan-speed controller manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX6635MSA+  
- **Package:** 8-pin SOIC  
- **Operating Voltage Range:** 3V to 5.5V  
- **Temperature Measurement Range:** -55°C to +125°C  
- **Accuracy:** ±1°C (from +60°C to +100°C)  
- **Resolution:** 0.125°C  
- **Interface:** SMBus/I²C-compatible  
- **Fan Control Output:** PWM (Pulse-Width Modulation)  
- **Programmable Fan Speed Control:** Yes  
- **Alarm Output:** Overtemperature alert  

### **Descriptions:**  
- The MAX6635MSA+ is a precision temperature sensor with an integrated fan-speed controller.  
- It monitors the temperature of a remote diode-connected transistor (e.g., CPU diode) and an internal sensor.  
- It provides closed-loop fan control to optimize cooling while minimizing acoustic noise.  

### **Features:**  
- **Dual Temperature Monitoring:** Measures both remote and internal temperatures.  
- **Programmable Fan Speed:** Adjusts fan speed based on temperature thresholds.  
- **SMBus/I²C Interface:** Allows communication with a microcontroller or host system.  
- **High Accuracy:** ±1°C accuracy over a critical temperature range.  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **Overtemperature Alarm:** Provides alert if temperature exceeds set limits.  

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