Infineon´s flexible portfolio of automotive qualified LIN alternator regulator ICs complies with various LIN specifications (incl. VDA) and helps to simplify design.
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:
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.
In automobiles alternators regulators are used in to charge the battery and to power the electrical system when its engine is running.
The Infineon alternator control ICs are monolithic full featured regulators specifically designed for closed loop voltage control for 12 V automotive multi-phase alternators with a rotating field winding. This regulator is able to communicate with an engine-management or energy-management ECU via a standard LIN1.3 (datalink layer) interface. By using freely adjustable parameters, the regulator is able to operate even without any communication interface. They are qualified according to AEC-Q100 and tailored to withstand the harsh conditions of the automotive environment.
They are qualified according to AEC-Q100 and tailored to withstand the harsh conditions of the automotive environment. The regulators are able to communicate with an engine management or engery management ECU through a standard LIN interface. The battery voltage is regulated at a precise value between 10.6 V and 16 V. 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 and thus qualified and released by leading OEMs.
