概览

ADT7460 是一款温度监控器和多重 PWM 风扇控制器，适用于需要主动式系统冷却的噪声敏感型应用。它可监控最多两个远程传感器二极管的温度及其自身内部温度。它可以测量和控制最多四个风扇的速度，让这些风扇以可能的最低速度运行，实现最低噪声。自动风扇速度控制回路可在既定温度下优化风扇速度。独特的动态 Tmin 控制模式可实现对系统温度/声音的智能管理。使用 THERM 输入，可监控系统散热方案的有效性。ADT7460 还通过将双向 THERM 引脚用作输出，为系统提供重要的高温保护，以防系统或组件过热。

  • Thermal Management

  • Personal Computers

  • Controls and monitors up to 4 fan speeds
  • 1 on-chip and 2 remote temperature sensors
  • Dynamic Tmin control mode optimizes system acoustics intelligently
  • Automatic fan speed control mode controls system cooling based on measured temperature
  • Enhanced acoustic mode dramatically reduces user perception of changing fan speeds
  • Thermal protection via the THERM output
  • Processor thermal control circuit via THERM input
  • 2-wire and 3-wire fan speed measurement
  • Limit comparison of all monitored values

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
