The IK8001 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 set-point voltage reference selected by the
Engine Control Unit (ECU) via L-terminal protocol is temperature flat. The alternator
voltage regulator IC has the standby mode with small current consumption.
