TLE88812TNAKSA1 Overview

The alternator control IC TLE8881-2TN 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 communication interface. The TLE8881-2TN is fully compliant to various LIN Alternator Regulator specifications (VDA, RSA-Nissan and HKMC).
