概览

ADM1027 控制器是一个完善的系统监控器和多 PWM 风扇控制器，用于需要主动系统冷却的噪声敏感型应用。它可以监控 12 V、5 V、2.5 V CPU 电源电压及其自身的电源电压。它可以监控最多两个远程传感器二极管的温度，加上自己的内部温度。它可以测量和控制最多四个风扇的速度，以便它们以最低可能速度运行，实现最低噪声。自动风扇速度控制环路可针对某个给定温度优化风扇速度。对控制环路参数进行编程之后，ADM1027 可以变化风扇速度而无需 CPU 干预。

  • Up to 8 Channel Voltage Input ADC
  • 3 Zone Temperature Sensor (2 Remote, 1 Local)
  • Up to 4 Fan Speed Counters
  • Up to 3 Pulse Width Modulation (PWM) Outputs for Fan Speed Control
  • SMBus Interface
  • Automatic Fan Speed Control Loop for Acoustic Reduction
  • Ability to Measure the Speed of a Fan with No Tachometer Output (i.e., a 2-Wire Fan)
  • Up to 5 General Purpose Input Pins
