TLE8881-2 Data Sheet .infineon. Rev. 1.00 2019-05-29 Alternator Control IC with LIN Interface Description The device is based on Infineon’s power technology SPT which allows bipolar and CMOS control circuitry to be integrated with DMOS power devices on the same monolithic circuitry. The battery voltage is regulated at a precise value between 10.6 V and 16 V. In case of munication loss, the regulator is able to proceed with the voltage regulation by using adjustable default values. A fixed frequency PWM voltage is set at an output pin to excite the excitation coil of the alternator. The TLE8881-2 is equipped with special protection circuitry as well as circuitry to control the excitation voltage slew rate to reduce EMI. Therefore the device meets the specific ESD and...
