TLE8880
Alternator Regulator with LIN Interface
The alternator control IC TLE8880 is a monolithic full featured regulator specifically
designed for closed loop voltage control. It can be used in 12V automotive multi phase
alternators with a rotating field winding. This regulator is able to communicate with
an Engine-Management or Energy-Management ECU through a standard LIN interface.
The battery voltage is regulated at a precise value between 10.6V and 16V. By using
free-adjustable parameters, the regulator is able to operate even without any commu-
nication interface.
The TLE8880 is compliant to the VDA LIN Alternator Regulator specification.
The output driver stage consists of a High-Side DMOS with a typical R
DS(on)
of 60mΩ for
up to 12A excitation current to the field winding. The chip has 8kV ESD protection for
alternator lines. The chip contains an EEPROM with adjustable parameters that can be
programmed in order to customize the alternator for the specific OEM or application
needs.
Applications
12V automotive alternators with LIN interface
12V truck alternators with LIN interface
