Description

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 output current levels even

when the application is running.

L9907 is equipped with 2 current sense amplifiers

with configurable mode, gain and offset to

guarantee maximum flexibility for phase or

ground current sense strategy.

Full diagnostic is available through SPI.
