L9474N:Alternator Voltage Regulator with rvc interface

The L9474N is a monolithic multifunction generator voltage regulator intended for use in automotive applications.

This device regulates the output of an automotive generator by controlling the field winding current by means of a variable frequency PWM high side driver.

The setpoint voltage reference is selected by the ENGINE CONTROL UNIT via RVC protocol.
