Product brief
TLE888x
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.
Key features TLE888x family
Full digital and fast PI regulation
High-side DMOS with RDS(on) of 60 mΩ
LIN 1.3, LIN 2.1, LIN2.2
Very low stand-by current of 60 µA typ.

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:
Key benefits TLE8881-2TN
