Product brief TLE888x Flexible LIN alternator regulator IC family The Infineon alternator control ICs are monolithic full featured regulators specifically de- Key features TLE888x family signed for closed loop voltage control for 12 V automotive multi-phase alternators with a rotating field winding. They are qualified according to AEC-Q100 and tailored to withstand Full digital and fast PI regulation the harsh conditions of the automotive environment. The regulators are able to commu- High-side DMOS with R of 60 m DS(on) nicate with an engine management or engery management ECU through a standard LIN LIN 1.3, LIN 2.1, LIN2.2 interface (LIN 1.3/LIN 2.1/LIN 2.2 see product table on page 2). The battery voltage is Very low stand-by current of 60 A typ. regulated at a precise value between 10.6 V and 16 V. By using free-adjustable parame- Reverse battery protected up to -2.5 V ters, the regulators are able to operate even without any communication interface. High ESD resistivity of 8 kV Duty cycle-range from The family is compliant to various LIN alternator regulator specifications (see product 0 to 100 percent table on page 2) and thus qualified and released by leading OEMs. Load Response Control (LRC) Temperature range -40C to 175C The output driver stage consists of a high-side DMOS for up to 12 A excitation current to Digital temperature compensation the field winding. The product family provides 8 kV ESD protection for all alternator lines. Available in TO-220-5-12 with The EEPROM with adjustable parameters offers a customization of the alternator to the straight leads specific OEM or application needs. The TLE8881-2, latest addition to the Infineon LIN alternator regulator IC family, builds Key benefits TLE8881-2TN upon the success of the existing ICs (TLE8880, TLE8881, TLE8886) while also offering several advantages: Easy switch Easy switch from existing applications using MFC or LIN interface Assisting functions to simplify Flexibility (LIN interface and enhanced EEPROM) design-in into existing Enhanced regulation behavior. applications with MFC interface Compatible to existing Applications Infineon LIN alternator ICs 12 V automotive alternators with LIN interface Compliant to various LIN 12 V truck alternators with LIN interface generator regulator specifications 12 V aftermarket alternators Flexibility 12 V industrial generators LIN 1.3, LIN 2.1 & LIN 2.2 Fully configurable LIN IDs and filters Enhanced EEPROM for customer specific adjustments Enhanced regulation behavior Speed dependent current limitation Speed and voltage dependent regu- lation parameter settings Adapting overvoltage protection at low speed (Low HEO) www.infineon.com/alternatorProduct brief TLE888x Flexible LIN alternator regulator IC family Application support Block diagram Infineon also provides an interface board (ACIC Board) Regulation block VBA together with interface software VBA Battery measurement (Battery) Reliable and simple for fast design-ins Easy EEPROM programming Digital core EXC EXC PI regulator (Excitation) Strong customer support Filter, measurement units Low excitation on, high excitation o , phase signal boost, excitation current limitation regulation, load response control PEM signal generation + Failure detections Digital block LIN interface State machine GND LIN protocol + Registers (Ground) handler diagnosis Phase EEPROM LIN transceiver monitoring PH LIN (Alternator phase) Product family Product OPN Description LIN interface TLE8880TN TLE8880TNAKSA1 Compliant to LIN VDA specification LIN 1.3 (Datalink layer) LIN 2.1 (Physical layer) TLE8881TN TLE8881TNAKSA1 Compliant to LIN HKMC specification LIN 1.3 (Datalink layer) LIN 2.1 (Physical layer) TLE8886TN Variant 1 TLE8886TNAKSA1 Compliant to LIN Renault Nissan specification LIN 2.1 (Datalink layer) TLE8886TN Variant 2 TLE8886TNAKSA2 Compliant to LIN VDA specification LIN 2.1 (Datalink layer) TLE8881-2TN TLE88812TNAKSA1 Compliant to LIN VDA, Renault Nissan and HKMC specification LIN 1.3 (Datalink layer), LIN 2.1, LIN 2.2 (Datalink and Physical layer) ACIC BOARD ACICBOARDTOBO1 Interface board for Infineon LIN alternator control IC family Published by Please note Additional information Infineon Technologies AG THIS DOCUMENT IS FOR INFORMATION PURPOSES ONLY AND For further information on technologies, our products, the 81726 Munich, Germany ANY INFORMATION GIVEN HEREIN SHALL IN NO EVENT BE application of our products, delivery terms and conditions REGARDED AS A WARRANTY, GUARANTEE OR DESCRIPTION OF and/or prices, please contact your nearest Infineon Technologies 2019 Infineon Technologies AG.
