Infineon TLE8881-2TN Alternator Regulator IC product picture

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
  • LIN 1.3, LIN 2.1, LIN2.2
  • Very low stand-by current of 60 µA

 

Additional features

  • Reverse battery protected up to -2.5 V
  • High ESD resistivity of 8 kV
  • Temperature range -40 °C to 175 °C
  • Digital temperature compensation
  • Available in TO-220-5-12 with straight leads

 

Additional Benefits:

  • Assisting functions to simplify design-in into existing applications with MFC interface
  • Compliant with various LIN generator regulator specifications (e.g. VDA, RSA-Nissan, HKMC)
  • Flexibility
  • Fully configurable LIN IDs and filters
  • Enhanced EEPROM for customer-specific adjustments
  • Speed-dependent current limitation
  • Speed and voltage-dependent regulation parameter settings
  • Adapting overvoltage protection at low speed (Low HEO)

 

Applications

  • 12 V automotive alternators with LIN interface
  • 12 V truck alternators with LIN interface
  • 12 V aftermarket alternators
  • 12 V industrial generators
