L9907 Automotive FET driver

L9907 is a gate driver unit controlling 6 N-channel FETs for brushless DC motors in automotive applications. Each pre-driver channel can be controlled independently allowing the implementation of all kinds of electric motor control strategy. The base gate output current is set via an external resistor, while via SPI it is possible to select among 4 gate outp.
