ADT7467中文资料Remote Thermal Monitor and Fan Controller数据手册ONSEMI规格书

描述 Description

The ADT7467 controller is a thermal monitor and multiple PWM fan controller for noise-sensitive or power sensitive applications requiring active system cooling.The ADT7467 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 that they operate at the lowest possible speed for minimum acoustic noise.

特性 Features

Controls and monitors up to 4 fans
High and low frequency fan drive signal
1 on-chip and 2 remote temperature sensors
Series resistance cancellation on the remote channel
Extended temp measurement range, up to 191°C
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 feature via THERM output
Thermal control circuit via THERM input

应用 Application

Thermal Management
Notebook and Desktop ComputersGame ConsolesRFID Readers
