TLE7259-3LE Overview
A LIN transceiver, also called a Local Interconnect Network physical-layer interface, connects a vehicle’s protocol controller to the physical LIN bus. It combines a bus driver, receiver, wake-up logic, and protection functions into one device. In the vehicle electronics hierarchy, the TLE7259-3LE belongs to the interface-IC family and connects low-rate serial-control networks to modules such as door controls, seat controls, lighting modules, and body-control systems.
The verified TLE7259-3 features include a 20 kbps maximum data rate, an 8 μA sleep current, and high EMC performance for LIN networks. Its integrated wake-up and protection features support low-power body-network operation and robust communication in electrically demanding vehicle environments. The 5.5 V to 27 V operating supply range allows use in conventional automotive electrical systems where transient and EMI conditions must be considered.
The device provides a physical bus-driver interface between the LIN protocol controller and the LIN bus. At the protocol level, the host controller handles framing, addressing, and higher-layer messaging, while the transceiver translates digital controller signals into LIN bus levels and returns received bus information through RXD. The integrated protection and wake-up functions reduce the need for separate interface circuitry, although external network protection and layout practices still matter in production designs.
Typical uses include LIN door modules, central locking, window and seat controls, ambient-lighting controllers, climate-control peripherals, body-control units, and other low-cost automotive subnetworks. The TLE7259-3LE is most appropriate when the design needs LIN communication between a low-rate embedded controller and distributed vehicle peripherals.
For PCB implementation, place the transceiver near the LIN connector or bus routing point, keep the LIN trace short and isolated from sensitive analog and high-speed digital signals, and provide the external pull-up and bus capacitance required by the application. Verify sleep-current behavior, bus timing, wake-up polarity, EMC performance, and supply decoupling against the manufacturer datasheet.
This page combines verified manufacturer specifications, sourcing context, application guidance, and drop-in-replacement analysis. It is intended to help engineers evaluate the TLE7259-3LE for automotive LIN designs while clearly separating verified values from information that still requires design-specific verification.

Typical Applications
TLE7259-3LE is suitable for 6 applications: Automotive Door Control Module, Central Locking and Body Electronics, Seat and Window Control, Ambient Lighting Controller, Climate-Control Peripheral Network, In-Vehicle Sensor and Actuator Network.
Automotive Door Control Module
The TLE7259-3LE fits a LIN door-control subsystem that distributes lock, window, mirror, or switch commands between an in-vehicle controller and peripheral modules. Its verified 2.4 kbps to 20 kbps LIN range covers common low-rate body-network communication, while the 8 μA sleep current helps limit standby demand when the module is parked. The transceiver’s integrated wake-up and protection features support a compact physical-layer implementation. In the ECU, it connects the LIN controller to the bus wiring, while external connector protection, bus pull-up selection, and PCB isolation still require application-level validation.
Recommended
Central Locking and Body Electronics
Use the TLE7259-3LE where a body-control unit communicates with a distributed locking or convenience subsystem over a LIN network. The 20 kbps maximum rate is appropriate for low-bandwidth command and diagnostic traffic, and the integrated wake-up function can support modules that must respond after a low-power interval. The device’s high-EMC positioning is relevant because vehicle wiring can couple external noise into the bus. Place the transceiver near the connector or protected bus entry, keep the LIN route away from high-current switching paths, and verify wake-up polarity and sleep current in the complete ECU.
Recommended
Seat and Window Control
The TLE7259-3LE can connect a seat, window, or switch-control module to an in-vehicle LIN subnet when the required baud rate is within 2.4 kbps to 20 kbps. Its 8 μA sleep current is useful for parked-vehicle modules, while integrated protection helps the interface operate in a harsh automotive electrical environment. The LIN controller manages message scheduling and diagnostics; the transceiver supplies the physical bus-driver and receive path. Confirm the exact pinout, pull-up value, bus capacitance, and wake-up configuration in the official Infineon datasheet before releasing the PCB.
Recommended
Ambient Lighting Controller
A LIN-connected ambient-lighting controller is a practical application for the TLE7259-3LE because vehicle lighting modules typically exchange short commands rather than high-bandwidth data. The transceiver supports 2.4 kbps to 20 kbps communication, allowing the controller to coordinate lighting commands over an existing body network. Its sleep current of 8 μA helps manage standby consumption, and the integrated wake-up and protection functions simplify the interface around the bus. The lighting module still needs suitable driver transistors or LED-control circuitry, and the LIN bus must be protected from connector transients and ESD events.
Recommended
Climate-Control Peripheral Network
The TLE7259-3LE can serve as the physical interface for a climate-control peripheral connected to a vehicle LIN subnet. Fan, flap, temperature, and control commands generally fit the device’s verified 2.4 kbps to 20 kbps range, while the low 8 μA sleep current supports energy-conscious parked operation. Integrated wake-up and protection features help the module respond after a low-power interval and tolerate the electrical conditions associated with vehicle wiring. The controller must still configure LIN timing and diagnostics, and the final design should validate conducted immunity, bus capacitance, and wake-up behavior under the vehicle’s operating conditions.
Recommended
In-Vehicle Sensor and Actuator Network
The TLE7259-3LE is appropriate for a small in-vehicle LIN network that connects a controller to distributed sensors or actuators. LIN’s single-wire bus architecture and the transceiver’s 2.4 kbps to 20 kbps range suit low-data-rate status, command, and diagnostic links. The device provides the physical interface between the protocol controller and bus, while its 8 μA sleep current helps limit standby load. Designers should account for the bus pull-up, total network capacitance, termination strategy, ESD protection, and the separation between LIN routing and noisy power or motor-switching paths.

Key Differentiators

- Integrated automotive network functions (vs TLE7259-3GE)
Design Notes
Place the TLE7259-3LE close to the LIN connector or protected bus entry and keep the LIN route short. Route the single-wire LIN bus away from switching nodes, high-current motor paths, crystal clocks, and sensitive analog inputs. Provide the external bus pull-up and protection components at the point where the harness enters the PCB, and verify the final network capacitance against the 2.4 kbps to 20 kbps operating range.
Decouple the transceiver supply locally and confirm that the 5.5 V to 27 V operating range has adequate transient margin for the vehicle electrical environment. The verified 8 μA sleep current should be measured in the complete module because the LIN pull-up, wake-up circuit, regulator, and connected peripherals contribute additional consumption. Review reverse-battery, load-dump, and ESD requirements against the manufacturer protection guidance before production.
Keep the LIN trace geometry controlled and avoid long parallel runs with noisy power or motor traces. Use a continuous ground reference beneath the interface where the package and PCB stackup allow, and place ESD or transient-protection devices close to the connector. Confirm the exposed-pad or thermal requirements of the exact PG-TSON-8 package from the Infineon datasheet rather than inferring them from the package name.
A LIN transceiver is not interchangeable solely with another part labeled LIN transceiver. Check pin names and functions, supply range, wake-up polarity, sleep behavior, bus timing, protection, and package footprint before substitution. In particular, a listing that names PG-DSO-8-16 rather than PG-TSON-8 requires careful footprint review and must not be treated as drop-in without manufacturer confirmation.
Compliance Information
The provided manufacturer and distributor search results identify the part as an automotive LIN transceiver but do not explicitly state RoHS, REACH, lead-free, halogen-free, conflict-minerals, or AEC-Q100 status. Compliance fields remain unknown rather than inferred.
