Description and Introduction

#.3V Multiprotocol Software-Selectable Cable Terminators and Transceivers The MAX3172CAI is a precision, dual-output temperature sensor and fan-speed controller manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX3172CAI  
- **Package:** 28-pin SSOP  
- **Operating Voltage Range:** 3V to 5.5V  
- **Temperature Measurement Range:** -40°C to +125°C  
- **Temperature Accuracy:** ±1°C (typical)  
- **Fan Control Outputs:** Two PWM outputs for fan speed control  
- **Communication Interface:** SMBus/I²C-compatible  
- **Resolution:** 11-bit for temperature, 7-bit for fan speed  
- **Supply Current:** 1mA (typical)  

### **Descriptions:**  
The MAX3172CAI is a high-accuracy temperature sensor with integrated fan-speed control. It monitors the temperature of two remote diode-connected transistors (or its own internal sensor) and adjusts fan speeds using PWM outputs. It is designed for thermal management in systems such as servers, telecom equipment, and industrial applications.  

### **Features:**  
- Dual PWM fan-speed control outputs  
- Supports both internal and external temperature sensing  
- Programmable temperature thresholds with hysteresis  
- Automatic fan-speed adjustment based on temperature  
- SMBus/I²C interface for communication  
- Low operating current for power efficiency  
- Fault detection for open/short sensor conditions  
- RoHS-compliant  

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