TLE7268SKXUMA1 - Dual 20 kbps LIN Transceiver | Infineon
Référence : TLE7268SKXUMA1 ✓ ActifTLE7268SKXUMA1 Présentation
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.

Applications typiques
TLE7268SKXUMA1 convient pour 6 applications: Automotive Body Control Module, Vehicle Gateway and LIN Network Bridge, Climate Control and Seat Module, Automotive Sensor and Actuator Node, Automotive Lighting Control Module, Automotive Access and Door Electronics.
Automotive Body Control Module
The TLE7268SKXUMA1 fits an automotive body-control module that must connect separate LIN sub-networks for doors, seats, lighting, or climate equipment. Its two independent LIN channels support communication rates up to 20 kbps while reducing the number of physical transceiver packages compared with a two-device implementation. The 3.3 V and 5 V digital I/O compatibility supports common automotive controller interfaces, while Sleep-mode wake-up capability and low BUSx leakage help the module control standby behavior without unnecessarily loading inactive buses. Layout should preserve the manufacturer PG-DSO-14 footprint and route each LIN line away from sensitive high-speed signals.
Recommandé
Vehicle Gateway and LIN Network Bridge
The TLE7268SKXUMA1 is appropriate for a vehicle gateway that interfaces two LIN domains while coordinating data exchange with higher-speed vehicle networks. Each LIN channel can operate up to 20 kbps, and the device is compliant with ISO 17987-4, LIN Specification 2.2 A, and SAE J2602, helping standardize physical-layer behavior across the sub-network. Its dual-channel construction saves board area, but the gateway designer must still implement the protocol stack, bus termination, wake-up routing, and fault recovery in the host controller. The low Sleep-mode consumption is particularly useful for parked-vehicle power-management strategies.
Recommandé
Climate Control and Seat Module
A climate-control or seat-adjustment ECU can use the TLE7268SKXUMA1 when it serves multiple low-speed LIN peripherals, such as a blower controller, door module, or sensor cluster. The two independent transceivers provide a compact way to attach the ECU to separate buses at rates up to 20 kbps. Compatibility with 3.3 V and 5 V digital I/O levels lets the host processor interface directly when its logic levels meet the device requirements. Because LIN is a single-wire network, PCB layout should minimize stubs, maintain the specified bus termination arrangement, and keep radio-frequency or high-speed digital traces spatially separated from BUS1 and BUS2.
Recommandé
Automotive Sensor and Actuator Node
The TLE7268SKXUMA1 can support compact sensor or actuator nodes that need access to one or two LIN networks. At a maximum 20 kbps, the interface targets low-bandwidth automotive functions rather than multimedia or high-speed sensor streaming. The device’s low Sleep-mode current and wake-up capability help nodes remain responsive without holding the vehicle network in an active state, while low BUSx leakage reduces unintended loading on shared conductors. For a single-purpose node, one channel may be unused; for a dual-function module, both channels can operate independently. Final validation should include bus timing, wake-up behavior, and fault-state recovery from the manufacturer data sheet.
Recommandé
Automotive Lighting Control Module
The TLE7268SKXUMA1 is suitable for lighting-related body modules that receive commands over LIN while coordinating lamps, switches, or ambient-light sensors on another LIN domain. Two independent channels support up to 20 kbps, which matches typical command-and-status traffic associated with vehicle lighting subsystems. Its 3.3 V and 5 V digital I/O compatibility broadens controller options, and its low-power sleep behavior is useful when the vehicle is parked. Because lighting modules can sit near motors and relays, the implementation should keep BUS routing away from switching nodes and use the manufacturer’s recommended grounding and decoupling arrangement to preserve communication reliability.
Recommandé
Automotive Access and Door Electronics
Door locks, window switches, seat controls, and access modules commonly use LIN for distributed vehicle electronics. The TLE7268SKXUMA1 fits an access ECU that must communicate with peripherals on two separate buses, providing rates up to 20 kbps in a PG-DSO-14 surface-mount package. Low BUSx leakage is beneficial on shared single-wire networks, particularly when multiple nodes enter sleep or partially powered states. Wake-up capability allows the module to respond after low-current parking. The host controller must still handle LIN scheduling and diagnostics, and the board must follow the exact PG-DSO-14 land pattern and bus-routing recommendations from the official manufacturer data sheet.

Notes de conception
Use the exact PG-DSO-14 land pattern and pin assignment published in the Infineon TLE7268 data sheet. The supplied verified excerpts do not include the individual pin names or complete footprint drawing, so do not infer the bus, logic, enable, or supply connections from a generic LIN-transceiver symbol. Keep BUS1 and BUS2 routes short, preserve the recommended termination implementation, and place protection or common-mode components directly along the physical path from the connector or harness to the device.
Design the sleep and wake-up behavior as part of the vehicle power architecture rather than treating it as an isolated transceiver feature. The verified data sheet confirms very low Sleep-mode current consumption, wake-up capability, and low BUSx leakage, but it does not provide numeric current or supply limits in the supplied excerpts. Confirm those values in the complete data sheet and verify that the host controller can initiate or detect wake-up events without continuously powering the LIN bus.
Route the two LIN bus traces as single-wire communication lines with minimal branch stubs, compatible characteristic impedance, and the termination arrangement required by the LIN network design. Keep the LIN traces away from switching power nodes, motor outputs, relay contacts, and high-speed clocks or data lines. Because both channels are physically independent, preserve separation between BUS1 and BUS2 routing, and verify each network’s remote wake-up and dominant-state behavior in a multi-node bench test.
