Description and Introduction

±1°C, SMBus-Compatible Remote/Local Temperature Sensors with Overtemperature Alarms The MAX6657YMSA+ is a temperature sensor and fan-speed controller manufactured by Maxim Integrated. Below are the factual details from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX6657YMSA+  
- **Type:** Temperature Sensor and Fan-Speed Controller  
- **Package:** 8-pin SOIC (MSOP)  
- **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  
- **Fan Control:** PWM output for fan-speed regulation  
- **Interface:** I²C/SMBus-compatible  
- **Resolution:** 0.125°C per LSB  
- **Programmable Alert Function:** Overtemperature alarm  
- **Power Consumption:** Low power operation  

### **Descriptions:**
The MAX6657YMSA+ integrates a high-accuracy temperature sensor with a fan-speed controller. It monitors the temperature of a remote diode-connected transistor (e.g., CPU diode) and adjusts fan speed via PWM control to optimize cooling while minimizing noise. It communicates over I²C/SMBus for configuration and temperature readings.

### **Features:**
- **Remote and Local Temperature Sensing:** Supports external diode and internal sensor.  
- **Programmable Fan Control:** Adjusts fan speed based on temperature thresholds.  
- **Overtemperature Alarm:** Configurable alert output.  
- **Low Power Operation:** Suitable for battery-powered applications.  
- **Small Form Factor:** 8-pin MSOP package for space-constrained designs.  
- **Wide Temperature Range:** Suitable for industrial and computing applications.  

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