Technical content

Flexible LIN alternator regulator IC family The Infineon alternator control ICs are monolithic full featured regulators specifically de- signed for closed loop voltage control for 12 V automotive multi-phase alternators with a rotating field winding. They are qualified according to AEC-Q100 and tailored to withstand the harsh conditions of the automotive environment. The regulators are able to commu- nicate with an engine management or engery management ECU through a standard LIN interface (LIN 1.3/LIN 2.1/LIN 2.2 – see product table on page 2). The battery voltage is regulated at a precise value between 10.6 V and 16 V. By using free-adjustable parame- ters, the regulators are able to operate even without any communication interface. The family is compliant to various LIN alternator regulator specifications (see product table on page 2) and thus qualified and released by leading OEMs. The output driver stage consists of a high-side DMOS for up to 12 A excitation current to the field winding. The product family provides 8 kV ESD protection for all alternator lines. The EEPROM with adjustable parameters offers a customization of the alternator to the specific OEM or application needs. The TLE8881-2, latest addition to the Infineon LIN alternator regulator IC family, builds upon the success of the existing ICs (TLE8880, TLE8881, TLE8886) while also offering several advantages: › Easy switch from existing applications using MFC or LIN interface › Flexibility (LIN interface and enhanced EEPROM) › Enhanced regulation behavior.
