Description and Introduction

2C Accurate Remote/Local Temperature Sensor with SMBus Serial Interface The MAX6690MEE is a temperature sensor and voltage monitor manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Part Number:** MAX6690MEE  
- **Package:** 16-QSOP (QSOP-16)  
- **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  
- **ADC Resolution:** 7-bit for remote temperature, 8-bit for local temperature  
- **Interface:** SMBus/I²C-compatible  
- **Number of Temperature Channels:** 2 (1 remote diode, 1 local)  
- **Voltage Monitoring Channels:** 5  
- **Alarm Output:** Programmable overtemperature/undervoltage alarm  

### **Descriptions:**
The MAX6690MEE is a high-accuracy temperature sensor and voltage monitor designed for system monitoring applications. It measures the temperature of a remote diode-connected transistor (e.g., CPU diode) and its own local temperature. It also monitors up to five system voltages, providing overtemperature and undervoltage alerts via an interrupt output.

### **Features:**
- **Dual Temperature Monitoring:**  
  - Remote diode temperature sensing (±1°C accuracy)  
  - Local temperature sensing  
- **Voltage Monitoring:**  
  - Tracks five system voltages (scaled via external resistors)  
- **Programmable Alarms:**  
  - Overtemperature and undervoltage thresholds  
  - Interrupt output for fault conditions  
- **Digital Interface:**  
  - SMBus/I²C-compatible (up to 400kHz)  
- **Low Power Consumption:**  
  - Typically 300µA operating current  
- **Wide Supply Range:**  
  - 3V to 5.5V operation  
- **Compact Package:**  
  - 16-pin QSOP for space-constrained applications  

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