L9915 Description
The device is a monolithic alternator voltage regulator intended for use in automotive application. It includes the control section, the field power stage, fault diagnostic circuit which drives a warning lamp, and the protection against short circuits. This device regulates in close loop the output of an automotive generator by controlling the field winding current by means of a pulse-width modulation (PWM) high...
