DESCRIPTION
It includes the control section, fault diagnostic circuit which drives a warning lamp, and the protection against short circuits. This device regulates in closed loop the output of an automotive generator by controlling the field winding current by means of a Pulse-Width Modulation (PWM) of an external high side or low side driver at fixed frequency.
