Description and Introduction

±1°C, SMBus-Compatible Remote/Local Temperature Sensor with Overtemperature Alarm The MAX6642ATT92+ is a 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:** MAX6642ATT92+  
- **Package:** 8-Pin TDFN (3mm x 3mm)  
- **Operating Voltage Range:** 3.0V to 5.5V  
- **Temperature Measurement Range:** -55°C to +125°C  
- **Accuracy:** ±1°C (from +60°C to +100°C)  
- **Interface:** SMBus/I²C-Compatible  
- **Fan Control:** PWM Output for Fan Speed Regulation  
- **Resolution:** 8-Bit (0.5°C per LSB)  
- **Shutdown Current:** <1µA  

### **Descriptions:**  
The MAX6642ATT92+ is a high-accuracy temperature sensor with an integrated fan-speed controller. It monitors the temperature of a remote thermal diode (e.g., CPU) and adjusts fan speed via PWM output to maintain optimal cooling. It communicates over an SMBus/I²C interface and includes features like overtemperature alarms.

### **Features:**  
- **Dual Temperature Monitoring:** Measures both local (on-chip) and remote (external diode) temperatures.  
- **Programmable Fan Control:** Adjusts fan speed based on temperature readings.  
- **Overtemperature Alarm:** Triggers an alert when temperatures exceed user-defined thresholds.  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **Small Form Factor:** Compact 8-pin TDFN package for space-constrained designs.  
- **Wide Operating Range:** Supports industrial and consumer applications.
