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 R_DS(on)of 60 mΩ

LIN 1.3, LIN 2.1, LIN2.2

Very low stand-by current of 60 µA typ.

Reverse battery protected up to -2.5 V

High ESD resistivity of 8 kV

Duty cycle-range from

›

The family is compliant to various LIN alternator regulator specifications (see product

table on page 2) and thus qualified and released by leading OEMs.

0 to 100 percent

Load Response Control (LRC)

Temperature range -40°C to 175°C

Digital temperature compensation

Available in TO-220-5-12 with

straight leads

›

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:
