ON Semiconductor ADT7473ARQZ-REEL Temperature Sensor and Fan Controller

The ADT7473ARQZ-REEL from ON Semiconductor is a versatile and efficient solution for thermal management in a wide range of electronic applications. This integrated circuit (IC) is designed to monitor and control the temperature and fan speed within systems such as personal computers, servers, and other embedded systems to ensure optimal performance and prevent overheating.

Key Features:

• Temperature Monitoring: The ADT7473ARQZ-REEL is capable of monitoring the temperature of up to three remote sensor diodes and its own internal temperature. This allows for precise temperature measurements across different components within the system.
• Fan Speed Control: Equipped with two fan speed control channels, this IC can manage the speed of up to two fans based on the temperature data it collects. This ensures that fans are only running as fast as necessary, reducing noise and power consumption.
• Programmable PWM Outputs: The device features two programmable pulse-width modulation (PWM) outputs which allow for precise control over the fan speed.
• I²C-Compatible Interface: For easy integration into most systems, the ADT7473ARQZ-REEL communicates via an I²C-compatible serial bus, providing flexibility in system design and the ability to work with a variety of microcontrollers.
• Versatile Power Supply: It operates over a wide supply voltage range of 3.0V to 5.5V, making it suitable for various applications.

Applications:

• Desktop and notebook computers
• Servers and server farms
• Telecommunication equipment
• Embedded systems
