  • 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.

    主要特性

    • AEC-Q100 qualified
    • System in package smart power alternator regulator and 8-bit microcontroller (non-monolithic approach)
    • Protected high/low side field pre-driver for external MOS
    • Field short circuit protection
    • Regulated voltage driven by ECU (programmable protocol driven)
    • Regulated voltage thermally compensated (without protocol)
    • Lamp driver (wake up and warning detection)
    • Self start function
    • Load response control (LRC)
    • Field monitor (FM) output
    • Thermal shutdown
    • Package TQFP44EP (10 x 10 mm)
