The L9924L is a controlled multifunctional alternator regulator intended to be used in cars, commercial and agricultural vehicles, with support for 12 V and 24 V systems. The control can be achieved through different communication protocols: LIN, RCV, PCM, C_term, BSS. It is a System-In-Package solution with smart power alternator regulator IC coupled with a 8-bit microcontroller (non-monolithic approach). 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.
