L9484 Datasheet PDF - STMicroelectronics

Description
The L9484 is a monolithic multifunction alternator voltage regulator intended for use in automotive charging applications.
L9484 regulates the output of an automotive generator by controlling the field winding current by means of a variable frequency PWM high side driver.
