TLE7259-2GU Présentation
A LIN transceiver is the physical-layer interface between a microcontroller or LIN protocol controller and the vehicle's LIN bus. The TLE7259-2GU converts controller-side serial signals into LIN bus levels, receives bus signals for the controller, and provides the electrical characteristics required by an in-vehicle network. It belongs to the broader hierarchy of interface IC, transceiver, communications transceiver, and automotive network interface.
The TLE7259-2GU is a follow-up product to the TLE7259-2GE and provides the same functions and pin compatibility. Verified data identifies it as a full-duplex, single-transceiver device with a 10.4 kBaud listed data rate in distributor listings, while the manufacturer datasheet describes operation from 2.4 kBaud to 10.4 kBaud according to SAE J2602. The distinction matters because the TLE7259-2GU is specifically positioned for the stated LIN network range rather than a general-purpose CAN interface.
The device is intended for automotive electronic control units, body modules, door modules, seat modules, lighting controllers, sensor interfaces, and other low-speed vehicle-network nodes. Its 8-pin SOIC package supports conventional surface-mount assembly, while the 7 V to 27 V supply range matches the verified component specification. The operating temperature range is listed as -40 C to 150 C in the verified GlobalSpecs data, making it relevant to automotive temperature environments.
For PCB design, preserve the verified pin compatibility with the TLE7259-2GE and place the transceiver close to the LIN bus connection. The LIN bus requires an appropriate transceiver-level bus interface, protection strategy, and decoupling arrangement defined by the surrounding vehicle-network design. The TLE7259-2GU is a surface-mount SMD device in cut-reel packaging according to the verified source data. Use the manufacturer datasheet for exact pin names, application circuitry, electrical limits, and external-component recommendations before releasing a design.
This product page combines verified specifications, source links, package information, and application context for engineers evaluating the TLE7259-2GU. It also distinguishes the TLE7259-2GU from merely functional interface alternatives and highlights the importance of confirming pin compatibility, supply range, protocol, and automotive requirements during substitution.

Applications typiques
TLE7259-2GU convient pour 6 applications: Automotive Body Control Module LIN Interface, Vehicle Door and Seat Module Communication, Automotive Lighting Control Node, Automotive Sensor Interface Module, In-Vehicle Network Gateway Interface, Low-Speed Vehicle Network Diagnostic Interface.
Automotive Body Control Module LIN Interface
The TLE7259-2GU fits a body-control or door-module LIN node because it is a dedicated 1-transceiver physical-layer interface for in-vehicle networks. Its verified 7 V to 27 V supply range and -40 C to 150 C operating-temperature listing match an automotive control-unit environment more closely than a generic logic interface. Place it between the MCU or LIN controller and the LIN wiring, then use the manufacturer-defined bus and supply protection. The key design constraint is protocol-specific implementation: the device is for LIN, not CAN, and the 2.4 kBaud to 10.4 kBaud SAE J2602 range must be checked against the network timing budget.
Recommandé
Vehicle Door and Seat Module Communication
A door or seat module commonly uses a LIN subnetwork to connect switches, sensors, and actuators with a central controller. The TLE7259-2GU provides the physical transceiver layer while the microcontroller handles frame generation, diagnostics, and higher-level control. Its single-driver, single-receiver arrangement is appropriate for a point-to-point node on the LIN bus. The verified 300 mV receiver hysteresis provides a specified input-level distinction, while the package is an 8-pin SOIC suitable for conventional surface-mount assembly. Exact pin names, bus termination strategy, and protection components must be taken from the manufacturer datasheet rather than inferred.
Recommandé
Automotive Lighting Control Node
The TLE7259-2GU can serve as the LIN physical interface for an automotive lighting controller or a distributed lamp module. Its LIN-specific protocol support avoids using a generic transceiver whose signal levels and timing are intended for another bus. The verified 7 V to 27 V supply specification aligns with vehicle-powered electronics, while the -40 C to 150 C operating-temperature listing supports harsh internal vehicle conditions. Design the PCB so that the transceiver and bus connection are placed according to the manufacturer's layout guidance, and check whether the vehicle environment requires external transient, ESD, or load-dump protection beyond the device specifications supplied here.
Recommandé
Automotive Sensor Interface Module
A LIN-connected sensor module can use the TLE7259-2GU to interface the sensor or conditioning electronics with the vehicle network. The transceiver handles the physical signaling between the local protocol controller and the LIN bus, while the controller performs measurement interpretation and diagnostic messaging. The device's one-driver, one-receiver topology fits a single LIN node, and its listed data-rate range must be compatible with the module's message timing. Because the supplied data does not include the complete electrical limit table or exact package pinout, consult the manufacturer datasheet for bus capacitance, pull-up or termination requirements, supply decoupling, and transient protection.
Recommandé
In-Vehicle Network Gateway Interface
The TLE7259-2GU is suitable for a LIN-facing interface within a vehicle network gateway or distributed control unit. It is intended to operate between a protocol controller and the physical bus, supporting the verified 2.4 kBaud to 10.4 kBaud range according to SAE J2602. This makes it relevant where a node must participate in a LIN subnetwork without relying on a higher-speed CAN or Ethernet physical layer. The design should account for the vehicle supply environment, low-current operating behavior if required by the system, and the external network protection specified by the manufacturer. The exact lifecycle and automotive-qualification status are not supplied and must be confirmed before production release.
Recommandé
Low-Speed Vehicle Network Diagnostic Interface
A diagnostic or service node connected to a LIN subnetwork can use the TLE7259-2GU as the physical-layer transceiver. The device's dedicated LIN function and verified single-driver, single-receiver arrangement make it more appropriate than a generic transceiver whose protocol and thresholds differ. Its operating-temperature listing of -40 C to 150 C is useful for modules mounted in harsh vehicle locations, but the actual diagnostic strategy remains the responsibility of the LIN controller and application software. Confirm the bus topology, wake-up behavior, fault handling, and electrical protection from the complete manufacturer datasheet before integrating the part into a service gateway.

Principaux différenciateurs
- Dedicated LIN physical-layer function (vs Generic CAN or RS-485 interface candidates)
- Verified same-family replacement path (vs TLE7259-2GE)
- Automotive-oriented supply and temperature specifications (vs TLE7259-2GE)
Notes de conception
Use the manufacturer datasheet package drawing as the authority for the PG-DSO-8 pinout because the supplied web snippets do not include the individual pin names or numbering. Place the transceiver close to the LIN connector or bus-routing point, keep the bus trace away from sensitive high-impedance analog paths, and route the supply return with a low-impedance path. Confirm the required external components before PCB release.
Do not treat a generic CAN or RS-485 transceiver as a substitute for the TLE7259-2GU. LIN uses a different physical-layer protocol and signal system, so protocol compatibility, bus topology, thresholds, timing, and protection requirements must all be checked. The only verified replacement candidate in the supplied data is the Infineon TLE7259-2GE, which the manufacturer describes as having the same functions and pin compatibility.
Design the vehicle supply path for the verified 7 V to 27 V operating range and verify transient, undervoltage, and overvoltage behavior against the complete manufacturer electrical-limit table. Because the supplied data does not include load-dump, reverse-battery, or short-circuit ratings, do not infer protection capability from the supply range alone. Coordinate fuse, clamp, filtering, and LIN-bus protection with the vehicle-level power architecture.
Informations de conformité
The supplied web results identify SAE J2602 as the LIN network standard, but do not provide verified RoHS, REACH, lead-free, halogen-free, conflict-minerals, or AEC-Q100 status for TLE7259-2GU.
