Alternator Regulator

The alternator control IC TLE***0 is a monolithic full featured regulator specifically designed for closed loop voltage control. It can be used in *2V automotive multi-phase alternators with a rotating field winding. This regulator is able to communicate with an Engine-Management or Energy-Management ECU through a standard LIN interface. The battery voltage is regulated at a precise value between *0.6V and *6V. By using free-adjustable parameters, the regulator is able to operate even without any communication interface. The TLE***0 is compliant to the VDA LIN Alternator Regulator specification. The output driver stage consists of a High-Side DMOS with a typical RDS(on) of *0mΩ for up to *2A excitation current to the field winding. The chip has 8kV ESD protection for alternator lines. The chip contains an EEPROM with adjustable parameters that can be programmed in order to customize the alternator for the specific OEM or application needs.
