Product Summary
The max6620ati+t is a Quad Linear Fan-Speed Controller. The max6620ati+t voltage for the fans are controlled directly over the I2C interface. Each output drives the base of an external bipolar transistor or the gate of a FET in highside drive configuration. Voltage feedback at the fans power-supply terminal is used to force the correct output voltage.
