产品概述

描述

The L9912 is a controlled multifunctional alternator regulator intended to be used in cars, commercial and agricultural vehicles. It supports 12 V system. The control can be achieved through different communication protocols: RCV, PCM, C_term. 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.
