Alternator Regulator with LIN

The 80310 is an integrated circuit intended to regulate the output

voltage of an automotive alternator.

The IC 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 80310 also provides a load response control mechanism

(LRC), and has an interface for the industry standard LIN protocol

(Revision 1.3) 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.

It can be programmed for most functions using OTP (Non-volatile

Memory) and fit a large number of alternators and applications.

Features

• High side field driver

• Internal freewheeling diode

•Up to 8.0 A rotor current (excitation coil)

• Load response control (LRC)

• Thermal protection

• Thermal compensation

• LIN interface

• Set point voltage selectable from 10.6 to 16 V

• Rotor control and die temperature monitoring via LIN
