Description

The ADT7476 controller is a thermal monitor and multiple PWM fan controller for noise-sensitive or power-sensitive applications requiring active system cooling. The ADT7476 can drive a fan using either a low or high frequency drive signal and can monitor the temperature of up to two remote sensor diodes plus its own internal temperature. The part also measures and controls the speed of up to four fans, so the fans operate at the lowest possible speed for minimum acoustic noise.
Features
• Monitors Up to Five Voltages
• Controls and Monitors Up to Four Fans
• High and Low Frequency Fan Drive Signal
• One On-Chip and Two Remote Temperature Sensors
• Extended Temperature Measurement Range Up to 191°C
• 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
• Monitors Performance Impact of Intel® Pentium® 4 Processor
• Thermal Control Circuit via THERM Input
• 3-wire and 4-wire Fan Speed Measurement
• Limit Comparison of All Monitored Values
• Meets SMBus 2.0 Electrical Specifications
• This Device is Pb-Free, Halogen Free and is RoHS Compliant
