TLE7259GT 概要
A LIN transceiver is an interface IC that connects a host microcontroller to a low-cost, single-wire automotive communication bus. LIN belongs to the broader CAN and automotive-network hierarchy: a CAN bus is a high-speed, multi-node network, while LIN uses a slower serial protocol optimized for cost-sensitive distributed vehicle subsystems. The TLE7259GT converts logic-level requests from a controller into LIN-bus signals and converts received bus levels into logic signals for the controller.
The TLE7259GT supports transmission rates through 20 kBaud and includes LIN specification compatibility for versions 1.3, 2.0, and 2.1. Its 7 V to 27 V operating supply range accommodates vehicle battery environments. Additional cited features include K-line support under ISO 9141, very high ESD robustness, and very low electromagnetic emission. These characteristics make the device relevant to LIN nodes requiring protocol compatibility and strong protection against conducted or capacitive bus disturbances.
Technically, the device combines a bus-side transmitter and receiver with the interface needed for an embedded host. A microcontroller can control bus dominance, monitor received frames, detect communication errors, and implement LIN scheduling. Because LIN commonly operates from a vehicle supply, the 27 V maximum operating voltage provides additional margin relative to 5 V transceiver packages, although the final design must still account for load dump and transient requirements at the wiring interface.
Typical applications include body-control modules, door and seat controllers, climate-control panels, lighting controllers, automotive gateways, and other distributed electrical subsystems. The K-line function broadens its utility in diagnostic or legacy vehicle interfaces, while the 20 kBaud rate matches common LIN physical-layer implementations.
Designers should verify bus termination, supply decoupling, transceiver sleep behavior, and protection requirements against the manufacturer datasheet before layout release. The LIN bus wiring is sensitive to ground offsets, capacitance, reflections, and ESD events, so PCB placement and vehicle harness design remain as important as the nominal IC specification.
This product page consolidates verified specifications, sourcing context, application guidance, and strict drop-in replacement criteria. Where the supplied web evidence does not establish a complete pin map, pricing schedule, or lifecycle designation, those details remain explicitly unverified rather than being inferred.

主な用途
TLE7259GT の用途: 6 件s: Automotive Body-Control Module, Door and Seat Control Module, Climate-Control Panel, Automotive Lighting Controller, Automotive Gateway and Diagnostic Interface, Industrial LIN-Capable Sensor Node.
Automotive Body-Control Module
The TLE7259GT fits a LIN-connected body-control module because it operates from 7 V to 27 V and supports communication through 20 kBaud. Its verified LIN specification compatibility with versions 1.3, 2.0, and 2.1 allows a host microcontroller to manage distributed door, lighting, or switch inputs without implementing the physical layer itself. The 8-pin PG-DSO-8 surface-mount package supports compact controller-board layouts. During implementation, verify the selected LIN frame schedule, wake-up and sleep behavior, and timing margins in the manufacturer documentation. Very low electromagnetic emission is beneficial when the module is installed near sensitive passenger-compartment electronics, while very high ESD robustness supports use in electrically exposed vehicle environments.
おすすめ
Door and Seat Control Module
The TLE7259GT is appropriate for a door or seat controller where a low-cost LIN subnet connects switches, motors, sensors, and indicators to a central body controller. Its 20 kBaud maximum rate matches typical LIN physical-layer communication, and the 7 V to 27 V supply range matches vehicle electrical environments. The K-line capability under ISO 9141 can add value in mixed diagnostic or legacy interfaces. Because the supplied data does not provide a complete pin map or external component values, the engineer must confirm wake-up, sleep, fault reporting, and bus termination requirements from the manufacturer datasheet before release.
おすすめ
Climate-Control Panel
A climate-control user panel can use the TLE7259GT as the LIN physical-layer interface between its host controller and a distributed HVAC node. The transceiver supports LIN specifications 1.3, 2.0, and 2.1 at rates through 20 kBaud, which covers conventional LIN subnet communication used for buttons, encoders, displays, and temperature-related commands. Its very low electromagnetic emission is useful in a passenger compartment containing sensitive control and display electronics. Layout should keep the transceiver close to the connector and provide clean return paths to reduce susceptibility to harness transients. Exact wake-up timing, sleep current, and diagnostic behavior remain datasheet-dependent and are not supplied in the verified excerpts.
おすすめ
Automotive Lighting Controller
The TLE7259GT can connect a lighting controller to a LIN-controlled lamp or switch module. Its 7 V to 27 V operating range provides compatibility with vehicle supply conditions, while the 20 kBaud LIN rate is sufficient for typical command and status traffic. The surface-mount PG-DSO-8 package simplifies automated PCB assembly alongside the controller MCU. Designers should use the verified very high ESD robustness as one part of the protection strategy, not as a replacement for connector or harness protection. Validate conducted immunity, radiated emissions, and sleep behavior in the final vehicle module because the supplied web data does not quantify those application-level test results.
おすすめ
Automotive Gateway and Diagnostic Interface
The TLE7259GT is suitable for a gateway or diagnostic interface that bridges an MCU-based control domain to a LIN subnet while retaining ISO 9141 K-line support. Combining LIN versions 1.3 through 2.1 with K-line capability can simplify mixed-platform vehicle architectures, although firmware must implement the relevant protocol behavior. The 8-pin surface-mount package allows placement near the harness connector, but cable routing and return-path design remain critical in a gateway enclosure. The verified low electromagnetic-emission characteristic supports systems containing multiple communication domains. Before schematic approval, confirm whether the K-line and LIN functions can operate concurrently and confirm all mode-transition timing from the manufacturer documentation.
おすすめ
Industrial LIN-Capable Sensor Node
The TLE7259GT can serve as the physical interface in a non-automotive LIN-capable sensor or actuator node when its 7 V to 27 V supply environment is appropriate. The 20 kBaud rate and LIN 1.3 through 2.1 support are compatible with conventional LIN networks used in distributed industrial controls. Its surface-mount PG-DSO-8 package reduces board area, and the cited very low electromagnetic emission is helpful around sensitive analog measurement circuits. Industrial implementations still need local transient suppression, grounding, and cable-length analysis because the verified data does not specify external protection networks or maximum bus topology. Firmware designers should also avoid assuming that automotive qualification data applies to an industrial deployment without additional review.

設計ノート
Place the TLE7259GT close to the LIN connector and route the bus as a short, controlled single-wire trace. Keep the device ground connected to a low-impedance vehicle ground or chassis reference, and verify that the PCB return path follows the connector shield or reference conductor. Exact external resistor, capacitor, and protection values are not present in the supplied evidence; obtain them from the manufacturer datasheet and reference design before finalizing the layout.
The verified features cite very low electromagnetic emission and very high ESD robustness, but these characteristics still require system-level validation. Keep the LIN trace away from clocks, switching regulators, display interfaces, and high-current motor or relay paths. Use a continuous ground reference, minimize loop area, and test the assembled module for conducted and radiated emissions in its final enclosure. Connector protection should be selected from the datasheet because its exact component values are not supplied.
Do not assume that a shared package name proves drop-in compatibility. Before substituting TLE7259-2GE or TLE72592GEXUMA4 for TLE7259GT, compare every pin, supply threshold, LIN timing parameter, wake-up and sleep mode, K-line behavior, and qualification record. The supplied cross-reference evidence identifies package, RoHS, and REACH differences but does not provide a complete electrical comparison, so a schematic-level review is mandatory.
コンプライアンス情報
The supplied TLE7259GT excerpts do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. A comparison page mentions RoHS and REACH differences between TLE7259-2GE and TLE72592GEXUMA4 but does not provide the exact target-part values.
