Infineon Technologies AG Special Purpose Regulators TLE8880TN2AKSA1

The TLE8880TN2AKSA1 is a monolithic automotive alternator regulator IC designed for 12 V multi-phase alternators with a rotating field winding. It features a closed-loop voltage control system that maintains battery voltage between 10.6 V and 16 V, and it is compliant with AEC-Q100 standards, making it suitable for harsh automotive environments. The IC supports communication with engine management systems via a LIN interface (LIN 1.3, LIN 2.1, LIN 2.2) and can operate without a communication interface through adjustable parameters. This regulator includes a high-side DMOS output driver capable of delivering up to 12 A excitation current, and it offers 8 kV ESD protection for all alternator lines. The device operates with a low standby current of 60 µA and is reverse battery protected up to -2.5 V. It is available in a TO-220-5 package with straight leads and is designed to function effectively across a temperature range of -40°C to 175°C. The TLE8880TN2AKSA1 is suitable for various applications, including automotive, truck, aftermarket alternators, and industrial generators.
