AR6000 Alternator regulator with LIN Rev. 5.2 17 June 2019 Product data sheet 1 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. 2 Simplified application diagram 1.5F/2.2F Master ECU B+A Stator Diagnose PH + - LIN EXC Battery Control AR6000 220pF GND Rotor Alternator Figure 1.Simplified application diagram (LIN Mode) 1.5F/2.2F B+A Stator PH + - LIN EXC Battery AR6000 GND Rotor Alternator Figure 2.Simplified application diagram (standalone, self-start mode)NXP Semiconductors AR6000 Alternator regulator with LIN 3 Features and benefits High-side field driver Internal freewheeling diode Up to 12.0 A rotor current (excitation coil) Load response control (LRC) and return LRC Current limitation and overcurrent protection Thermal protection Thermal compensation LIN 2.1 physical layer Set point voltage selectable from 10.6 V to 16 V Accurate rotor current measurement, die temperature, alternator speed, and battery voltage reported by LIN 4 Applications Automotive alternators 5 Orderable parts Table 1.Orderable part variations Part number Temperature (T ) Package A 1 MC33AR6000BGWS 40 C to +150 C die 1 MC33AR6000BGT 40 C to +125 C TO220 1 The AR6000 devices are configurable with one time programmable (OTP) options described in Table 58.
