TLE7259G 概述
A LIN transceiver is an interface IC that connects a microcontroller UART to a LIN bus. LIN, or Local Interconnect Network, is a low-cost, single-wire vehicle network commonly used for sensors, actuators, body electronics, and comfort systems. The transceiver translates logic-level signals between the host controller and the LIN physical bus, while wake-up and protection functions support reliable operation in electrically harsh environments. Its 20 kBaud maximum rate matches the source description for in-vehicle LIN networks.
The key verified characteristics are the 2.4 kBaud-to-20 kBaud data-rate range, 3.5 V-to-5.5 V supply range, integrated wake-up, integrated protection, and 8-pin SOIC construction. These features make the device applicable to distributed vehicle nodes where a host MCU requires a standardized LIN physical layer. The source does not provide verified values for transceiver mode, sleep current, bus thresholds, propagation delay, ESD rating, or absolute maximum ratings, so those parameters are not inferred here.
TLE7259G is most relevant to body and comfort modules, sensor interfaces, actuator controllers, door and window modules, climate-control systems, and other LIN subnets. The host microcontroller handles LIN frame generation and protocol timing; the transceiver supplies the physical-layer connection. Designers must confirm the complete LIN electrical specification, pinout, external components, supply sequencing, and protection requirements against the manufacturer datasheet before production release.
For PCB implementation, place the transceiver close to the LIN bus connection and route the single-wire bus away from sensitive analog and high-speed digital signals. The LIN bus requires an appropriate pull-up arrangement and protection strategy; exact resistor and protection values should follow the verified datasheet and system-level EMC requirements. Keep the supply and ground return paths short, and verify the device's wake-up behavior in the intended low-power architecture.
This page combines the verified TLE7259G source descriptions, pricing references, package information, and cross-reference findings with engineering selection context. The supplied data does not establish enough verified information to populate every electrical specification, complete pinout, lifecycle classification, or qualified drop-in alternative without risking an inaccurate replacement recommendation.

典型应用
TLE7259G 适用于 6 应用s: Automotive Sensor Node, Body Control Module, Door and Window Module, Climate-Control Subnetwork, Seat and Comfort Electronics, Actuator Controller.
Automotive Sensor Node
The TLE7259G fits an automotive sensor node because the verified device is designed for in-vehicle LIN networks and supports data rates from 2.4 kBaud to 20 kBaud. A microcontroller can handle sensor acquisition and LIN frame timing while the transceiver connects the node to the single-wire bus. Its integrated wake-up feature is useful for distributed nodes that must participate after a low-power state, while integrated protection supports the electrical environment of vehicle wiring. Exact temperature, ESD, thresholds, and bus-loading requirements must be verified in the datasheet.
推荐
Body Control Module
The TLE7259G is applicable to a body control module that connects switches, lamps, locks, or seat electronics to a LIN subnet. Its 20 kBaud maximum data rate matches the verified in-vehicle LIN use case, and the 3.5 V-to-5.5 V operating supply range supports regulated low-voltage nodes. The MCU should implement the LIN protocol and diagnostics while the transceiver handles the physical bus interface. Wake-up and protection integration can simplify a distributed architecture, but system EMC and vehicle qualification must be confirmed separately.
推荐
Door and Window Module
A door or window module can use the TLE7259G when the local actuator network is based on LIN. The transceiver provides the physical-layer connection for switch and motor-control nodes, while the host MCU manages state, diagnostics, debouncing, and actuator timing. The verified 2.4 kBaud-to-20 kBaud range covers low-speed vehicle control communication, and integrated wake-up supports modules that sleep between events. The final design must confirm whether the package, wake-up polarity, and protection requirements match the selected module architecture.
推荐
Climate-Control Subnetwork
The TLE7259G can be used in a climate-control LIN subnetwork for temperature sensors, fan commands, actuators, and panel interfaces. Its verified in-vehicle positioning and 20 kBaud capability are appropriate for distributed low-speed control nodes, while wake-up allows remote modules to respond after the vehicle network is energized. The MCU must handle the LIN protocol and local control logic. Before release, verify operating temperature, supply tolerance, bus protection, sleep behavior, and the exact external bus network requirements against the manufacturer documentation.
推荐
Seat and Comfort Electronics
Seat and comfort systems often distribute functions such as position sensing, motor control, occupancy indication, and switch status across vehicle subnets. The TLE7259G's verified LIN operation from 2.4 kBaud to 20 kBaud supports such low-bandwidth in-vehicle communication, while integrated wake-up and protection help fit a low-power distributed node. A suitable MCU performs application logic and diagnostics. Because the supplied source does not specify all timing, current, or environmental limits, validate the complete electrical interface and qualification requirements before production use.
推荐
Actuator Controller
The TLE7259G can serve as the bus interface in an actuator controller that receives commands from a vehicle LIN master. The host MCU owns command interpretation, safety checks, motor or relay timing, and diagnostic reporting, while the transceiver handles the physical LIN connection. The verified 20 kBaud capability is appropriate for low-speed actuator networks, and integrated wake-up supports event-driven operation. The design must still verify bus pull-up configuration, external protection, operating temperature, fault behavior, and the manufacturer's recommended application circuit.

设计说明
Place the TLE7259G and its external LIN-network components close to the bus connector and chassis-entry protection structure. Keep the single-wire LIN route short, controlled, and away from high-current switching nodes and sensitive analog traces. The supplied data confirms an 8-pin SOIC package and LIN operation, but it does not provide the complete reference layout or external component values; follow the manufacturer application guidance and validate the final PCB against the vehicle EMC requirements.
Design the node's supply path around the verified 3.5 V to 5.5 V operating range and ensure the MCU and transceiver share a stable low-impedance ground reference. The supplied data does not specify decoupling values, current limits, or startup sequencing, so those details must be taken from the manufacturer datasheet. Check the worst-case vehicle supply transients and the external protection network before treating the device as production-ready.
Do not select a replacement from function alone. A LIN transceiver substitute must match the package footprint, pin assignments, supply range, bus thresholds, timing, wake-up behavior, sleep behavior, protection method, and automotive qualification. The verified cross-reference data names TLE7259-2GE, NCV7361AD, and SN65HVD230, but it does not prove drop-in compatibility for TLE7259G. Confirm every interface parameter before substitution.
Treat the supplied search snippets as leads rather than complete electrical specifications. The 23-page AllDataSheet result and the Mouser PDF establish that a TLE7259G datasheet exists, but the prompt does not provide the pin table, timing curves, thresholds, absolute maximum ratings, thermal data, or qualification declarations. Download and review the manufacturer document before layout, firmware integration, or safety-related release.
合规信息
The supplied verified web data describes the TLE7259G as an automotive LIN transceiver but does not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. These fields remain unknown rather than assumed.
