TLE8881-2-TN TLE8881-2-TN PG-TO-220-5-12 Straight Leads TLE8881-2 Data Sheet Rev. 1.00 www.infineon.com 1 2019-05-29 TLE8881-2 Alternator Control IC with LIN Interface Description The device is based on Infineons 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 communication 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 EMC requirement of the harsh automotive environment. The following main features are implemented: Closed loop voltage control By controlling the excitation PWM duty cycle of the excitation output stage, the TLE8881-2 regulates the output voltage to an internal default voltage setpoint or to a voltage setpoint controlled by the engine management or energy management ECU via the LIN interface. The regulation is processed in a full digital and fast PI regulator. Load Response Control (LRC) The load response control (LRC) prevents engine speed hunting and vibration due to electrical loads which cause abrupt torque loading of the engine at low speeds. Self start detection The TLE8881-2 automatically wakes up the state machine if the frequency and amplitude of the phase signal is above a specific threshold. This allows the alternator to function in spite of interrupted or broken LIN communication. Pre-excitation The excitation coil is pre-energized with a small fixed excitation PWM duty cycle coming from the excitation output stage of the TLE8881-2 to provide a stable phase voltage input signal. Phase Signal Boost (PSB) The phase signal boost system of the TLE8881-2 maintains a proper phase signal for rotor speed measurement. Low Voltage Excitation Switch On (LEO) At very low battery voltage loading is immediately induced by increasing the current in the excitation coil until a minimal defined voltage is achieved. High Voltage Excitation Switch Off (HEO) At very high boardnet voltage, the excitation is immediately switched off in order to stop generating power. Excitation current measurement The measurement of the excitation current inside the rotor is used by the ECU to calculate and monitor the torque on the engine. Data Sheet 2 Rev. 1.00 2019-05-29
