TLE7257LEXUMA1 - 20 kbps LIN Transceiver | Infineon
MPN: TLE7257LEXUMA1 ✓ সক্রিয়TLE7257LEXUMA1 সারাংশ
A LIN transceiver is the physical-layer interface between a LIN protocol controller and a vehicle's LIN wiring. LIN is a low-cost, single-wire serial network used for distributed automotive functions such as body electronics, comfort controls, lighting, seat controls, and sensor nodes. The TLE7257LE translates logic-level signals between the controller and the physical LIN bus while supporting a maximum specified data rate of 20 kbps.
The TLE7257LEXUMA1 provides one transmit channel and one receive channel for integration into a LIN node. Its integrated wake-up function supports low-power vehicle-network designs, while integrated protection features help the interface withstand the electrical conditions encountered in automotive wiring. The manufacturer identifies the device as ISO 17987-4 compliant, making it suitable for LIN physical-layer implementations requiring that interoperability specification.
The PG-TSON-8-1 package uses eight pins and is intended for surface-mount PCB assembly. Its compact form factor is useful for electronic control units where the LIN interface must be placed close to the controller, connector, or protection network. Automotive qualification, production status, detailed electrical limits, exposed-pad construction, and ordering-code-specific attributes should be confirmed against the manufacturer ordering information before a safety-related or high-volume design is released.
Typical applications include body-domain controllers, door and seat modules, climate-control equipment, lighting control modules, sensor interfaces, and other distributed automotive systems connected through a LIN bus. The transceiver can also be used in LIN gateways or diagnostic interfaces when the system controller requires a dedicated physical-layer transceiver.
Design the LIN bus connection with the supply, ground, transceiver, connector, and external protection network arranged to minimize loop area and maintain signal integrity. Confirm the device's exact pin assignment, recommended external components, bus capacitance, pull-up implementation, and electrical limits in the manufacturer datasheet before PCB release.

সাধারণ ব্যবহার
TLE7257LEXUMA1 এর জন্য উপযুক্ত 6 অ্যাপ্লিকেশনs: Automotive Body-Control Module, Door and Comfort-Control Node, Automotive Lighting Controller, Vehicle Sensor Interface, Climate-Control Module, LIN Gateway and Diagnostic Interface.
Automotive Body-Control Module
The TLE7257LEXUMA1 fits a LIN-connected body-control module that communicates with distributed door, lighting, seat, or climate functions. Its one-transmitter/one-receiver arrangement connects a LIN protocol controller to the physical vehicle bus at rates up to 20 kbps. Integrated wake-up allows the module to respond after a low-power state, while integrated protection supports an interface intended for in-vehicle wiring. Place the transceiver near the controller and bus protection components, and follow the manufacturer application circuit for external termination and supply decoupling.

Door and Comfort-Control Node
A door or comfort-control node can use the TLE7257LEXUMA1 as the physical-layer interface between a LIN controller and the vehicle's single-wire bus. A maximum LIN rate of 20 kbps is suitable for low-bandwidth commands and diagnostic data in distributed body systems. The integrated wake-up feature supports power-conscious modules that must detect network activity, and the compact 8-pin PG-TSON-8-1 package limits board area near the connector or controller. Verify the exact external pull-up, protection, and decoupling implementation before PCB approval.

Automotive Lighting Controller
The TLE7257LEXUMA1 can provide the LIN physical layer for a distributed lighting controller that receives commands from a central body network. The one-transmitter/one-receiver interface handles communication between the local protocol controller and the LIN wiring while supporting data rates up to 20 kbps. Its wake-up capability helps the module limit active-system consumption, and integrated protection is valuable in an automotive environment with electrically connected accessories. Keep the transceiver path short, follow the recommended bus network, and confirm grounding and connector-side protection in the vehicle design.

Vehicle Sensor Interface
A remote vehicle sensor node can employ the TLE7257LEXUMA1 to connect a local controller to a LIN subnet carrying sensor readings and configuration commands. LIN's supported communication bandwidth is sufficient for the device's documented maximum rate of 20 kbps, while the integrated wake-up function helps avoid continuous operation when the node is inactive. The 8-pin surface-mount package is practical for compact sensor electronics. Use the manufacturer's bus termination, common-mode protection, and grounding recommendations to maintain reliable communication over vehicle wiring.
সুপারিশকৃত
Climate-Control Module
The TLE7257LEXUMA1 is appropriate for a climate-control unit that participates in a LIN network alongside other distributed vehicle functions. Its 1/1 transceiver architecture separates the transmit and receive functions needed by the associated protocol controller, and its LIN interface supports operation up to 20 kbps. Wake-up support can reduce the energy required to remain responsive to bus activity, while integrated protection assists interface robustness. Place the device according to the manufacturer layout guidance and validate the external network components across all vehicle operating conditions.
সুপারিশকৃত
LIN Gateway and Diagnostic Interface
A gateway or diagnostic interface can use the TLE7257LEXUMA1 as the physical-layer transceiver on a LIN branch connected to a protocol controller. The one-transmitter/one-receiver configuration supports bidirectional bus signaling while the 20 kbps maximum matches the stated LIN use case. Wake-up and protection features help the branch operate predictably in a low-power automotive network. Follow the manufacturer recommendations for supply filtering, transceiver placement, external bus components, and protected connections to the wiring harness.

ডিজাইন নোট
Place the TLE7257LEXUMA1 close to the LIN protocol controller and the entry point of the wiring-harness protection network. Keep the transceiver, controller, supply decoupling, and connector-side protection on a controlled return path to minimize differential noise and common-mode disturbance. Follow the manufacturer layout drawing for pin routing and exposed-pad treatment rather than inferring thermal or electrical requirements from the generic TSON dimensions.
Implement the external LIN bus pull-up or termination exactly as specified by the Infineon application circuit. The target supports LIN communication up to 20 kbps, but correct bus loading, routing, grounding, and protection remain necessary to reach that rate reliably. Avoid long unprotected branches, maintain consistent reference grounding, and review connector and harness discontinuities before conducting signal-integrity testing.
Do not treat every TLE7257 ordering suffix as an automatic drop-in substitute. The candidate TLE7257SJXUMA1 belongs to the same 8-pin TSON family, but production qualification, temperature grade, supply limits, lifecycle status, and exact pin behavior must be checked for the installed design. Obtain the ordering table and datasheet for both suffixes, then compare every parameter affecting board operation, protection, and vehicle qualification.
Use the supply-decoupling and grounding arrangement specified by the manufacturer for the TLE7257LE. The integrated wake-up function can support low-power behavior, but wake thresholds, operating modes, and current consumption depend on the exact ordering code and surrounding circuitry. Validate the controller's interaction with wake-up, reset, and bus states in both powered and unpowered conditions before production testing.
কমপ্লায়েন্স তথ্য
RoHS-compliant and lead-free status are identified in the manufacturer-linked catalog information. AEC-Q100 qualification for the exact ordering suffix must be confirmed from the manufacturer ordering documentation.
