enly

ADT74701控制器是一个多通道温度传感器和PWM风扇控制器和风扇转速监控器需要主动冷却系统。它的目的是直接连接到一个I2C®总线。TheADT7470可以监控多达10个菊链式TMP05温度传感器。它还可以监视和控制的四个风扇，速度自动或手动控制回路。Feature：

       

• Monitors up to 10 remote temperature sensors       
  
• Monitors and controls speed of up to 4 fans independently       
  
• PWM outputs drive each fan under software control       
  
• FULL_SPEEDinput allows fans to be blasted to maximum  speedby externalhardware       
  
• SMBALERT interrupt signals failures to system controller       
  
• Three-state ADDR pin allows up to 3 devices on a single bus       
  
• Temperature decoderinterpretsTMP05 temperature sensors and communicates values over I2C bus       
  
• Limit comparison of all monitored values       
  
• Supports fast I2C standard (400 kHz max)       
  
• Meets SMBus 2.0 electrical specifications (fully SMBus 1.1-compliant)
