Description

The L9914 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.

Features

 AEC-Q100 qualified

 High side field driver

The setpoint voltage reference is selected by the

engine control unit (ECU) via RVC protocol.
