TLE7258SJXUMA1 - 20 kbps LIN Transceiver | Infineon
MPN: TLE7258SJXUMA1 ✓ ActiveTLE7258SJXUMA1 Overview
A LIN transceiver is an interface IC that connects a microcontroller's serial data and control signals to the physical wiring of a Local Interconnect Network. Within the vehicle-network hierarchy, LIN is a low-cost, single-wire bus commonly used for non-critical body and comfort functions. The TLE7258SJXUMA1 forms the physical-layer boundary between the protocol controller and the LIN bus.
Key features include operation up to 20 kbps, compatibility with LIN versions 1.2 through 2.2A, and a selectable 3.3 V or 5.0 V regulated output for the associated controller. The device supports low-power operating modes and enters standby after power-up until the microcontroller asserts the EN input. These characteristics suit distributed automotive modules that need reliable communication without a high-bandwidth network connection.
The integrated voltage regulator reduces the external power-supply design required around the LIN transceiver. Wake-up and protection functions add system-level robustness for connected vehicle wiring, where transient energy and diagnostic bus activity must be handled close to the external connector. ISO 17987-4 compliance places the physical layer in a standardized automotive LIN framework, while SAE J2602-2 supports its use in the United States automotive market.
Typical applications include door and window modules, HVAC controls, ambient lighting, seat controls, dashboard accessories, and body-control nodes. The device is particularly appropriate where a LIN subnet connects a low-cost microcontroller to switches, sensors, or actuators over a single vehicle wire.
PCB design should preserve the transceiver's pin assignments, provide the required bus and supply decoupling specified by the manufacturer datasheet, and route the LIN connection to the protected connector. Confirm EMC, fault-tolerance, and wake-up behavior for the complete vehicle network rather than evaluating only nominal communication performance.
This page combines manufacturer specifications, sourcing guidance, package details, and application-oriented engineering guidance to support LIN bus design, component selection, PCB implementation, and supply-chain planning.

Typical Applications
TLE7258SJXUMA1 is suitable for 6 applications: Vehicle Body-Control Nodes, Door and Window Control Modules, HVAC Control Networks, Automotive Lighting Modules, Seat and Comfort-Control Modules, Automotive Sensor and Actuator Hubs.
Vehicle Body-Control Nodes
The TLE7258SJXUMA1 fits distributed body-control modules that communicate over a LIN subnet at up to 20 kbps. Its integrated 3.3 V or 5.0 V regulator can supply the associated microcontroller, while the 8-pin PG-DSO-8 package simplifies compact PCB placement. LIN 2.2A, ISO 17987-4, and SAE J2602-2 support make the interface appropriate for standardized vehicle-network functions. The design should verify wake-up behavior, bus fault recovery, and regulator current margin against the attached controller and actuator loads.
Recommended
Door and Window Control Modules
Door, window, mirror, and switch modules benefit from the TLE7258SJXUMA1 because LIN provides a cost-effective single-wire connection for distributed body functions. The transceiver supports 20 kbps communication and includes wake-up and standby behavior, allowing a sleeping controller to remain connected to the vehicle network. Its integrated regulator reduces the number of local supply components. Designers should check pull-up and bus-line implementation requirements, protected-connector behavior, and diagnostic wake-up patterns in the complete module.
Recommended
HVAC Control Networks
The TLE7258SJXUMA1 is suitable for HVAC controls where blower, temperature, and flap-control nodes can share a low-cost LIN bus. A 20 kbps physical-layer link is appropriate for these relatively low-bandwidth commands and status signals. The integrated 3.3 V or 5.0 V output supports controller supply integration, while low-power modes support vehicles that shut down body electronics. The bus transceiver must still be validated for motor-generated electrical noise, ground offsets, wake-up timing, and fault behavior across temperature extremes.
Recommended
Automotive Lighting Modules
Ambient-lighting, status-light, and exterior-lamp controllers can use the TLE7258SJXUMA1 where commands and diagnostics require a robust low-speed vehicle network rather than a high-bandwidth bus. The 20 kbps LIN interface, integrated regulator, and wake-up support simplify a distributed lighting node. Because LED drivers can introduce switching transients and ground disturbance, the implementation should separate sensitive transceiver supply paths from noisy actuator stages. EMC behavior and LIN waveform integrity should be checked with the final load and vehicle harness.
Recommended
Seat and Comfort-Control Modules
Seat-position, lumbar, heating, and occupant-comfort modules are representative LIN applications for the TLE7258SJXUMA1. The device links a microcontroller to switches, motors, or position sensors through a single vehicle-network wire at rates up to 20 kbps. Its standby and wake-up features support power-conscious body modules, and the integrated 3.3 V or 5.0 V regulator simplifies supply planning. Mechanical motor loads and actuator wiring remain important fault sources, so protection and wake-up behavior must be verified in the final harness.
Recommended
Automotive Sensor and Actuator Hubs
The TLE7258SJXUMA1 can terminate a LIN subnet used for simple sensors, switches, and actuators near a vehicle controller. Its integrated receiver and transmitter operate at up to 20 kbps, while the regulated output can power compatible local electronics. Wake-up functionality supports network-managed low-power operation, and the standardized LIN compliance supports interoperability across vehicle modules. Final validation should include bus-line capacitance, pull-up selection, sleep-current budget, diagnostic behavior, and protection under transient or short-circuit conditions.

Design Notes
The TLE7258SJXUMA1 accepts a 5.5 V to 18 V supply and provides a selectable 3.3 V or 5.0 V regulated output. Verify the regulator configuration, output-load limit, startup behavior, and local decoupling against the Infineon manufacturer datasheet. Place the input and output capacitors at the specified pins with short return paths, and account for automotive transient energy and ground offsets at the connector before the PCB is released.
Use the 8-pin PG-DSO-8 footprint from the manufacturer package drawing and preserve the recommended copper, solder-mask, paste, and exposed-pad geometry. Keep the LIN bus route away from switching nodes and motor-drive return currents. The bus connection should use the specified external network components, and the protected connector path should be routed to minimize coupling from unrelated vehicle electrical loads.
Do not assume that a shared family name guarantees an interchangeable part. Before replacing the TLE7258SJXUMA1, compare pin names, regulator output selection, LIN fault behavior, wake-up thresholds, current limits, temperature range, and ordering suffixes in each candidate's datasheet. Also confirm that the EN pull-down arrangement and post-power-up standby sequence match the external microcontroller design.
The LIN interface shares vehicle wiring with actuators and other modules, so protection and EMC performance depend on the complete bus implementation. Follow the manufacturer recommendations for bus-line components and layout, provide a controlled return path, and validate waveform symmetry and radiated emissions with the production harness. Avoid long unprotected branches or sharp routing that can increase coupling and bus-imbalance risk.
