The IK8006 is a monolithic alternator voltage regulator IC intended for use in
automotive application. It includes the control section, the field power stage and the
protection against short circuits. IC regulates the output voltage of an automotive
generator in close loop by control the field winding current with a Pulse-Width Modulation
(PWM) high side driver at fixed frequency. The alternator voltage regulator IC has the
standby mode with small current consumption when no activity pin Lamp and pin PH.
After the ignition is switched ON, the Lamp-terminal is connected to the battery via
the lamp. This voltage at Lamp terminal is wake-up signal for regulator. In case of missing
signal at Lamp terminal, the regulator will be activated after detection of a phase signal
induced by remanence of the rotor.
