The ADT7475ARQZ-REEL from Analog Devices is a thermal monitor and multiple PWM fan controller designed for noise-sensitive or power-sensitive applications requiring active system cooling. This device can drive a fan using either a low or high frequency drive signal. It monitors the temperature of up to two remote sensor diodes plus its own internal temperature.
The ADT7475 controller measures and controls the speed of up to four fans, optimizing fan speed for minimum acoustic noise based on measured temperature. It offers an automatic fan speed control mode and an enhanced acoustic mode to reduce user perception of changing fan speeds. The device also provides critical thermal protection via a bidirectional THERM pin.
This component operates with a supply voltage range of 3V to 3.6V, typically 3.3V. The operating temperature range is from -40°C to 125°C. It features an extended temperature measurement range up to 191°C. The ADT7475ARQZ-REEL supports I2C, SMBus, and other serial interfaces, meeting SMBus 2.0 electrical specifications. It is available in a 16-QSOP surface mount package and comes on tape and reel with a standard package quantity of 2500.
Key features include control and monitoring of up to 4 fans, high and low frequency fan drive signals, and 1 on-chip plus 2 remote temperature sensors. It also supports 3-wire and 4-wire fan speed measurement and limit comparison of all monitored values.
