Description and Introduction

Dual Mode⑩ 5V/Programmable Vicropower Voltage Regulators The MAX663CSA is a precision temperature sensor and fan controller manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
Maxim Integrated  

### **Description:**  
The MAX663CSA is a monolithic temperature sensor and fan controller designed for monitoring and controlling the temperature of electronic systems. It provides accurate temperature readings and can drive a fan to maintain optimal thermal conditions.  

### **Key Features:**  
1. **Temperature Sensing:**  
   - Measures temperature with an accuracy of ±3°C (typical) over the operating range.  
   - Operates over a temperature range of **-20°C to +125°C**.  

2. **Fan Control:**  
   - Provides PWM (Pulse Width Modulation) output for fan speed control.  
   - Adjustable fan speed based on temperature thresholds.  

3. **Output Options:**  
   - Analog voltage output proportional to temperature (10mV/°C).  
   - Digital PWM output for fan speed regulation.  

4. **Power Supply:**  
   - Operates from a **+4.5V to +5.5V** supply voltage.  
   - Low power consumption (typical **1.5mA** operating current).  

5. **Package:**  
   - **8-pin SOIC (Small Outline Integrated Circuit)** package.  

6. **Additional Features:**  
   - Built-in hysteresis to prevent fan oscillation near setpoints.  
   - External resistor allows adjustment of temperature thresholds.  

### **Applications:**  
- PC and server thermal management.  
- Industrial temperature monitoring.  
- Embedded system cooling control.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics and application circuits, refer to the official MAX663CSA datasheet.
