General description
The AR6000 is an integrated circuit intended to regulate the output voltage of an
automotive alternator.
It supplies a current via a high-side MOSFET to the excitation coil of the alternator and
provides an internal freewheeling diode. It keeps the battery at its nominal charge and
delivers current to electrical devices within the vehicle.
The IC provides a load response control mechanism (LRC), and has an interface for the
industry standard LIN protocol (v 1.3 or 2.1) to allow an ECU to control the regulated
voltage and the LRC rate among other parameters. The ECU can also read back
information about the status of the regulator and the alternator via LIN.
It can be programmed for most functions using OTP (fuses) and fits a large number of
alternators and applications.
