About

Automotive LIN transceivers for reliable in-vehicle networking

LIN transceivers connect a microcontroller to the single-wire Local Interconnect Network used in automotive electronic control units. Infineon's portfolio supports communication rates up to 20 kbit/s and offers basic, high-end, and dual-channel LIN options. The scalable family helps designers match communication, wake-up, low-power, and channel requirements while keeping the interface compact. Devices support worldwide automotive applications and follow current LIN standards and certification requirements.

Choose the right LIN transceiver family for your ECU

Infineon's automotive LIN portfolio provides a clear path from basic communication to greater performance and multi-channel integration. TLE7257x and TLE7258x cover basic single-channel LIN. TLE7259-3x adds high-end functionality for demanding designs, while TLE7268x combines two independent LIN channels in one device. Across the portfolio, designers can select sleep or standby behavior, wake-up functions, timeout options, and the package that best fits the ECU.

Basic LIN transceivers with ultra-low power consumption

TLE7257SJ/LE and TLE7258SJ/LE are basic LIN transceivers for commander and responder nodes. They support data rates up to 20 kbit/s and are available in PG-DSO-8 and PG-TSON-8 packages. Depending on the device, the ECU can power up in sleep or standby mode. Low BUS-pin leakage supports partially supplied networks, while ultralow sleep current helps reduce standby power. Pin-to-pin compatibility with established competitor devices can reduce development effort when migrating designs.

High-end LIN transceivers with fast programming support

The TLE7259-3GE/LE high-end LIN transceiver combines low-power modes with enhanced communication performance. Standby, sleep and flash modes support accelerated microcontroller programming, with flash-mode transmission up to 100 kbit/s. Improved receiver performance reduces propagation delay and increases delay symmetry. Digital I/O levels are compatible with 3.3 V and 5 V microcontrollers, and the devices are offered in PG-DSO-8 and PG-TSON-8 packages. Pin-to-pin compatibility helps shorten redesign and qualification work.

Dual LIN transceivers for compact multi-channel designs

TLE7268SK and TLE7268LC integrate two independent LIN transceivers in one package. This dual-channel approach reduces layout effort and offers flexible placement options for ECUs that require more than one LIN connection. The family supports up to 20 kbit/s and provides wake-up capability while minimizing current consumption in low-power operation. Compatibility with single-LIN portfolio pinouts supports modular ECU concepts. Package options include PG-DSO-14 and PG-TSON-14 for conventional and compact board designs.

LIN transceiver features that simplify automotive design

Infineon LIN transceivers are designed to make platform development and migration easier. The portfolio offers different package solutions, backward pin-to-pin compatibility with previous product versions and compatibility options for established competitor devices. These choices can reduce layout effort and support transitions between product families. Low-power operating states, low BUS-pin leakage and wake-up functions address energy-sensitive ECUs. High ESD robustness, strong EMC performance and worldwide OEM release support use across a broad range of automotive applications.

LIN transceiver packages, standards and applications

The LIN portfolio supports body and comfort functions including rain and light sensors, parking assistance, seat functions, pumps, fans and vehicle lighting. Single and high-end LIN products are available in PG-DSO-8 and PG-TSON-8, while dual LIN devices use PG-DSO-14 and PG-TSON-14. The leadless TSON-8 option supports automated optical inspection. Portfolio devices support communication up to 20 kbit/s and include products compliant with ISO 17987-4, LIN specification 2.2A and SAE J2602.
