Product Summary
The ADT7473ARQZ-REEL is a thermal monitor and multiple PWM fan controller for noise sensitive or power sensitive applications requiring active system cooling. The ADT7473ARQZ-REEL 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 they operate at the lowest possible speed for minimum acoustic noise.
Parametrics
ADT7473ARQZ-REEL absolute maximum ratings: (1)Positive Supply Voltage (VCC): 3.6 V; (2)Voltage on Any Input or Output Pin: -0.3 V to +3.6 V; (3)Input Current at Any Pin: ±5 mA; (4)Package Input Current: ±20 mA; (5)Maximum Junction Temperature (TJ max): 150℃; (6)Storage Temperature Range: -65 to +150℃; (7)Lead Temperature, Soldering IR Reflow Peak Temperature: 260℃; Lead Temperature (Soldering, 10 sec): 300℃; (8)ESD Rating: 1500 V.
Features
ADT7473ARQZ-REEL features: (1)Controls and monitors up to 4 fans; (2)High and low frequency fan drive signal; (3)1 on-chip and 2 remote temperature sensors; (4)Series resistance cancellation on the remote channel; (5)Extended temperature measurement range, up to 191℃; (6)Dynamic TMIN control mode optimizes system acoustics intelligently; (7)Automatic fan speed control mode controls system cooling based on measured temperature; (8)Enhanced acoustic mode dramatically reduces user perception of changing fan speeds; (9)Thermal protection feature via THERM output; (10)Monitors performance impact of Intel Pentium4 processor; (11)Thermal control circuit via THERM input; (12)3-wire and 4-wire fan speed measurement; (13)Limit comparison of all monitored values; (14)Meets SMBus 2.0 electrical specifications (fully SMBus 1.1 compliant); (15)Fully ROHS compliant.
