Infineon Technologies OptiMOS™5 40 V MOSFETs sTOLL power MOS package

The TLE8881-2, latest addition to the Infineon LIN alternator regulator IC family, is a monolithic full-featured regulator specifically designed for the closed-loop voltage control of 12 V automotive multi-phase alternators with a rotating field winding. The TLE8881-2 is AEC-Q100 qualified and tailored to withstand the harsh conditions of the automotive environment. The regulator is able to communicate with engine management or energy management ECU through a standard LIN interface (LIN 1.3 / LIN 2.1 / LIN 2.2). 

Key features

• Full digital and fast PI regulation
• High-Side DMOS with RDSON of 60mΩ
