Description	Quad Linear Fan-Speed Controller
Datasheet	MAX6620_MaximIntegratedProducts.pdf

The MAX6620 controls the speeds of up to four fans using four independent linear voltage outputs.

The drive voltages 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.
