  • The L9914 is a monolithic multifunction generator voltage regulator intended for use in automotive applications.

    This device regulates the output of an automotive generator by controlling the field winding current by means of a variable frequency PWM high side driver.
    The setpoint voltage reference is selected by the engine control unit (ECU) via RVC protocol.

    • AEC-Q100 qualified
    • High side field driver
    • Thermal protection
    • Field driver short circuit protection
    • RVC interface
    • Overvoltage protection
    • Complex diagnostics
    • Load response control
      • LRC rate 2.5 s (L9914A, L9914C)
      • LRC rate 5.0 s (L9914B)
