TLE7268SKXUMA1 - Dual 20 kbps LIN Transceiver | Infineon
Infineon Technologies TLE7268SKXUMA1 is an automotive dual LIN 2.2 transceiver that integrates two independent single-wire LIN transceivers in one PG-DSO-14 package. Each channel supports transmission rates up to 20 kbps, and the device is compliant with ISO 17987-4, LIN Specification 2.2 A, and SAE J2602. Its integrated interfaces are designed for 3.3 V and 5 V digital I/O levels, allowing connection to automotive body controllers, gateways, and other LIN nodes. The TLE7268SKXUMA1 also provides very low Sleep-mode current consumption with wake-up capability and very low leakage on the BUSx pins.
A LIN transceiver, short for Local Interconnect Network transceiver, is an interface IC that connects a microcontroller or body-control module to a LIN bus. LIN is a low-cost, single-wire automotive network derived from the CAN concept but optimized for slower communication, lower wiring complexity, and cost-sensitive vehicle subsystems. In the component hierarchy, the TLE7268SKXUMA1 is a LIN transceiver, then an automotive interface IC, then an interface semiconductor.
Key features include two independently usable LIN channels, operation to 20 kbps, compatibility with 3.3 V and 5 V digital logic, low Sleep-mode consumption, and wake-up capability. Compliance with ISO 17987-4, LIN Specification 2.2 A, and SAE J2602 supports integration into modern automotive communication systems. Very low BUSx leakage helps prevent unwanted bus loading and supports predictable behavior when connected LIN nodes enter low-power states.
The device provides the physical-layer interface between the host controller and each LIN bus. Its digital transmit and receive pins connect to a microcontroller, while BUS1 and BUS2 connect to the LIN network. The independent-channel architecture allows one transceiver package to serve two LIN networks, reducing component count and PCB area compared with two separate single-channel LIN transceivers. External implementation details, including bus termination, wake-up wiring, and logic pull-ups, must follow the manufacturer datasheet.
Typical uses include body-control modules, automotive gateways, seat and door modules, climate-control units, sensor nodes, and other ECUs connected by LIN sub-buses. Because the TLE7268SKXUMA1 supports two channels, it is especially useful where one ECU must interface with two separate LIN networks or where a gateway bridges multiple vehicle subsystems.
For PCB implementation, preserve the package-specific land pattern, place the transceiver close to the LIN connector or bus routing, and keep BUS traces away from sensitive high-speed signals. Decoupling and signal-integrity values are not specified in the supplied verified excerpts, so component selection and layout must be completed against the complete manufacturer datasheet.
This page consolidates verified manufacturer and distributor information, compliance statements, pricing status, and engineering guidance for the TLE7268SKXUMA1. It also distinguishes verified dual-LIN functionality from unavailable electrical details, preventing unsupported assumptions about pinout, thermal limits, or substitute compatibility.
