Description and Introduction

Dual Mode™ 5V Programmable Micropower Voltage Regulators The MAX663ESA+ is a temperature sensor and fan controller manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Category:** Temperature Sensor and Fan Controller  
- **Package:** 8-SOIC (0.154", 3.90mm Width)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Supply Voltage:** 3V to 5.5V  
- **Output Type:** Digital, PWM  
- **Accuracy:** ±3°C (from +60°C to +100°C)  
- **Resolution:** 1°C  
- **Interface:** I²C/SMBus-Compatible  
- **Fan Control:** Supports up to two fans  

### **Descriptions:**  
The MAX663ESA+ is a precision temperature sensor with an integrated fan controller. It monitors the temperature of a remote diode-connected transistor (e.g., CPU diode) and provides PWM fan speed control based on the measured temperature. It communicates via an I²C/SMBus interface for configuration and data reporting.  

### **Features:**  
- Monitors remote diode temperature (e.g., CPU or GPU)  
- Supports two fan speed control outputs (PWM)  
- Programmable temperature thresholds for fan control  
- Low power consumption  
- I²C/SMBus-compatible interface  
- Over-temperature alarm output  
- ±3°C accuracy (within +60°C to +100°C)  
- Small 8-pin SOIC package  

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

Application Scenarios & Design Considerations

Dual Mode™ 5V Programmable Micropower Voltage Regulators

Alternative Part Number

  • LTC1685CS8#PBF --: Pin-compatible dual comparator in SO-8 with similar supply range and speed, from the former Linear Technology line now under ADI.
  • TLV3201AIDBVR --: Low-power single comparator with rail-to-rail inputs, suitable replacement in SOT-23 or SO-8 adapters for general-purpose comparator applications.
  • LM393DR --: Industry-standard dual comparator in SO-8, widely available and cost-effective, though slightly slower than the original device.
