Alternator Regulator

Infineon’s monolithic alternator control ICs are designed for the voltage control of 12V automotive multi-phase alternators. The regulators are AEC-Q100 qualified and tailored to withstand the harsh conditions of the automotive environment. Their standard LIN interface enables a communication with an Engine-Management or Energy-Management ECU (LIN 1.3 / LIN 2.1 / LIN 2.2). By using free-adjustable parameters, the regulators are able to operate even without any communication interface.

The family is compliant to various LIN alternator regulator specifications (incl. VDA) and thus qualified and released by many OEMs.
The output driver stage consists of a High-Side DMOS for up to 12A excitation current. All products provide 8kV ESD protection. 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
• Flexibility
• Enhanced regulation behavior

Infineon’s monolithic alternator control ICs can be used in the  following 12V target applications: 12V automotive alternators with LIN interface, 12V truck alternators with LIN interface, 12V aftermarket alternators and 12V industrial generators.
