Description and Introduction

7-Channel Precision Temperature Monitor The MAX6636UP9A+T is a temperature sensor and fan-speed controller manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Part Number:** MAX6636UP9A+T  
- **Package:** 16-pin TSSOP (UP9A)  
- **Operating Voltage Range:** 3.0V to 5.5V  
- **Temperature Measurement Range:** -40°C to +125°C  
- **Accuracy:** ±1°C (from +60°C to +100°C)  
- **Resolution:** 0.125°C  
- **Interface:** SMBus/I²C-compatible  
- **Fan Control Output:** PWM (Pulse-Width Modulation)  
- **Number of Temperature Channels:** 2 (local + 1 remote diode)  
- **Remote Diode Support:** Yes (for CPU/GPU diode)  

### **Descriptions:**
- The MAX6636UP9A+T is a high-accuracy temperature sensor and fan controller designed for monitoring and regulating system temperatures in computing and industrial applications.  
- It supports both local and remote temperature sensing (via an external diode-connected transistor).  
- The device provides PWM-based fan-speed control to optimize cooling efficiency while minimizing noise.  
- It communicates via an SMBus/I²C interface for configuration and temperature reporting.  

### **Features:**
- **Dual Temperature Monitoring:** Measures local and remote diode temperatures.  
- **Programmable Fan Control:** Adjusts fan speed based on temperature thresholds.  
- **High Accuracy:** ±1°C accuracy in critical ranges.  
- **Low Power Consumption:** Optimized for energy-efficient systems.  
- **Flexible Configuration:** User-programmable temperature limits and hysteresis.  
- **Fault Detection:** Includes overtemperature alarms and fan-fault detection.  
- **Wide Operating Range:** Supports industrial and computing environments (-40°C to +125°C).  

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

Application Scenarios & Design Considerations

7-Channel Precision Temperature Monitor

Alternative Part Number

  • ADT7476AARQZ-REEL --: Multi-channel temperature monitor and fan controller with similar SMBus interface and remote diode sensing, suitable functional replacement.
  • LM95235CIMM/NOPB --: Remote diode temperature sensor with SMBus interface and local/remote channels, comparable accuracy and monitoring function.
  • EMC2305-1-AP-TR --: Fan controller with temperature monitoring and SMBus interface, offers similar system thermal management capability.
  • ADM1032ARZ-REEL7 --: Remote/local temperature sensor with SMBus interface, functionally similar to the MAX6636 and widely available from a different series.
  • EMC1403-A-AIZL-TR --: Multi-channel temperature sensor with SMBus interface, suitable as a functional substitute with a clearly different part series.
