Alternator Regulator with LIN
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.
- Keeps the battery at its nominal charge and delivers current to electrical devices within the vehicle.
- Interface for the standard LIN protocol (1.3 or 2.1) to allow an ECU to control the regulated voltage and the LRC rate among other parameters.
- The ECU also can read back information about the status of the regulator and the alternator via LIN.
- Can be programmed for most functions using OTP (Fuses) and fits a large number of alternators and applications
The AR6000 devices are configurable with One Time Programmable (OTP) options described in Table 55. For easy design-in, contact your local NXP sales representative to receive limited engineering samples in the TO-220 package configured to your system requirements.
