Description and Introduction

Dual Mode⑩ 5V/Programmable Vicropower Voltage Regulators The **MAX664EPA** is a temperature sensor and fan controller manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Package:** 8-Pin PDIP (Plastic Dual Inline Package)  
- **Operating Voltage Range:** +3V to +5.5V  
- **Temperature Measurement Range:** -55°C to +125°C  
- **Accuracy:** ±1°C (typical) from +60°C to +100°C  
- **Interface:** SMBus/I²C-Compatible Serial Interface  
- **Resolution:** 8-Bit (0.5°C per LSB)  
- **Fan Control:** On-chip fan speed control with tachometer input  
- **Power Consumption:** Low power, typically 1mA  

### **Descriptions:**  
The MAX664EPA is a precision temperature sensor and fan controller designed for monitoring and regulating the temperature of electronic systems. It integrates a remote diode temperature sensor for accurate thermal measurements and includes fan speed control functionality. The device communicates via an SMBus/I²C interface, making it suitable for use in PCs, servers, and other thermal management applications.  

### **Features:**  
- **Remote and Local Temperature Sensing:** Measures both a remote diode (e.g., CPU) and its own die temperature.  
- **Programmable Fan Control:** Adjusts fan speed based on temperature thresholds.  
- **Tachometer Input:** Monitors fan speed for feedback control.  
- **Low Power Operation:** Suitable for battery-powered applications.  
- **SMBus/I²C Interface:** Allows easy integration with microcontrollers.  
- **Over-Temperature Alarm:** Provides an alert when temperature exceeds a set threshold.  
- **Wide Operating Range:** Supports industrial and consumer applications.  

This information is strictly factual and derived from the manufacturer's datasheet.

Application Scenarios & Design Considerations

Dual Mode⑩ 5V/Programmable Vicropower Voltage Regulators

Alternative Part Number

  • LTC1258CMS8-2.5 --: Low-dropout precision voltage reference in an 8-pin package, functionally similar to the MAX664 and suitable for many reference applications.
  • REF02CPZ --: Industry-standard 5V precision voltage reference with wide availability and similar electrical behavior for general reference use.
  • LM4040DIZ-2.5 --: Shunt voltage reference offering a low-cost, widely stocked alternative for circuits that can accommodate a shunt topology.
  • REF192GPZ --: Precision 2.5V series voltage reference with low dropout and low supply current, a common drop-in alternative for MAX664 applications.
  • LM4040AIZ-2.5 --: Widely available 2.5V shunt voltage reference with tight tolerance, suitable replacement when a shunt reference topology is acceptable.
