ADT7473中文资料远程热监控器和风扇控制器数据手册ONSEMI规格书

描述 Description

The ADT7473/ADT7473-1 controller is a thermal monitor and multiple PWM fan controller for noise sensitive or power sensitive applications requiring active system cooling.The ADT7473/ADT7473-1 can drive a fan using either a low or high frequency drive signal, monitor the temperature of up to two remote sensor diodes plus its own internal temperature, and measure and control the speed of up to four fans so they operate at the lowest possible speed for minimum acoustic noise.

特性 Features

• Controls and monitors up to 4 fans
• 1 on-chip and 2 remote temperature sensors
• Extended temp measurement range, up to 191°C
• Automatic fan speed control mode controls system cooling based on measured temperature
• Thermal protection feature via THERM output
• 3-wire and 4-wire fan speed measurement

应用 Application

• Thermal Management
• Servers
• Game Consoles
• RFID Readers
