Description and Introduction

Dual Mode⑩ 5V/Programmable Vicropower Voltage Regulators The MAX664CSA is a temperature sensor and fan controller manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX664CSA  
- **Package:** 8-pin SOIC  
- **Operating Voltage Range:** 3V to 5.5V  
- **Temperature Measurement Range:** -40°C to +125°C  
- **Accuracy:** ±1°C (typical) from +60°C to +100°C  
- **Output Type:** Digital (SMBus/I²C-compatible interface)  
- **Fan Control:** Supports PWM (Pulse Width Modulation) fan speed control  
- **Resolution:** 0.125°C per LSB (Least Significant Bit)  
- **Supply Current:** 200µA (typical)  

### **Descriptions:**
- The MAX664CSA is a precision temperature sensor with an integrated fan controller.  
- It measures the temperature of a remote diode-connected transistor (e.g., CPU diode) and its own internal temperature.  
- It communicates via an SMBus/I²C interface for easy integration into digital systems.  
- The device includes programmable fan control to optimize cooling based on temperature readings.  

### **Features:**
- **Dual Temperature Monitoring:** Measures both remote and local temperatures.  
- **Programmable Fan Speed Control:** Adjusts fan speed via PWM output.  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **High Accuracy:** ±1°C accuracy in critical temperature ranges.  
- **Wide Operating Range:** Supports industrial and consumer applications.  
- **SMBus/I²C Interface:** Allows communication with microcontrollers.  
- **Thermal Alarm Output:** Provides overtemperature alerts.  

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

Application Scenarios & Design Considerations

Dual Mode⑩ 5V/Programmable Vicropower Voltage Regulators

Alternative Part Number

  • LTC1682CS8 --: Dual comparator in SO-8 with similar supply range and open-drain output, a common drop-in style replacement for MAX664 in many designs.
  • LM393M --: Industry-standard dual comparator in SO-8 with wide supply range and open-collector outputs, widely available and pin-compatible in most applications.
  • TLV3201AIDBVR --: Low-power push-pull comparator in SOT-23, suitable when a smaller package and lower current consumption are acceptable substitutes.
