TLE7257SJXUMA1 - 20 kbps LIN Transceiver | Infineon Technologies
Référence : TLE7257SJXUMA1 ✓ ActifTLE7257SJXUMA1 Présentation
A LIN transceiver is an interface integrated circuit that connects a host microcontroller or cluster controller to a single-wire Local Interconnect Network bus. The LIN bus belongs to the vehicle-network interface hierarchy, where physical-layer transceivers translate logic-level controller signals into bus-level signals and recover received data for the host processor.
Key features include support for data transmission rates up to 20 kbps, integrated wake-up, protection features, and an integrated voltage regulator. The PG-DSO-8 package matches the verified 8-SOIC, 3.90 mm-wide package designation. Its operating temperature range extends from -40 °C to 150 °C, making it appropriate for harsh automotive environments when the complete device qualification and system requirements are satisfied.
The TLE7257SJXUMA1 is listed for automotive AEC-Q100 applications and operates in a vehicle-network IC role. Its integrated regulator can support implementation of a protected transceiver supply, while the wake-up and protection functions reduce the external circuitry needed for a robust LIN node. Exact regulator output, supply limits, thresholds, and electrical timing values are not included in the supplied verified data and should be confirmed in the manufacturer datasheet.
Typical applications include LIN slave nodes in body-control modules, door and seat modules, climate-control equipment, lighting controllers, sensors, and other low-speed vehicle subsystems. Its 20 kbps capability matches LIN networks commonly used for distributed automotive body electronics, where deterministic communication and robust fault handling are more important than high-bandwidth performance.
When designing a PCB around the TLE7257SJXUMA1, use the manufacturer reference layout and verify bus termination, pull-up implementation, supply decoupling, and exposed-pad or thermal requirements for the exact PG-DSO-8 land pattern. Because the supplied data does not include a verified pin table, engineers should obtain the official pinout before routing the transceiver pins.
This page consolidates verified manufacturer and distributor information, automotive-interface specifications, application guidance, and replacement considerations. It also clearly separates confirmed characteristics from parameters that require confirmation from the official datasheet, helping engineers evaluate the LIN transceiver without relying on unverified generic part data.

Applications typiques
TLE7257SJXUMA1 convient pour 6 applications: Automotive Body-Control Module LIN Node, Door and Seat Control Module, Climate-Control and HVAC Module, Automotive Lighting Controller, Automotive Sensor and Actuator Hub, Low-Speed Vehicle Network Gateway.
Automotive Body-Control Module LIN Node
The TLE7257SJXUMA1 is appropriate for a body-control module that connects switches, lamps, locks, or seat mechanisms through a LIN subnetwork. Its confirmed support for communication rates up to 20 kbps matches the data rates used by distributed vehicle-body electronics. The integrated voltage regulator, wake-up function, and protection features can reduce the support circuitry required around the LIN physical layer. The device is also listed for automotive AEC-Q100 use and operates from -40 °C to +150 °C. Before routing the PCB, confirm the exact regulator behavior, bus thresholds, wake-up source, and pin assignments in the official datasheet.
Recommandé
Door and Seat Control Module
The TLE7257SJXUMA1 suits a door or seat controller that must communicate with a remote LIN slave over a cost-sensitive single-wire network. A maximum rate of 20 kbps is sufficient for switch states, motor commands, sensor values, and diagnostic information commonly assigned to LIN. Its wake-up functionality supports low-power vehicle modules, while integrated protection improves robustness against faults encountered on in-vehicle wiring. The PG-DSO-8 package also provides a compact surface-mount footprint for electronic door-lock, window, seat-position, and occupant-comfort assemblies. Exact input thresholds, current limits, and fault-recovery behavior must be verified against the manufacturer datasheet before production release.
Recommandé
Climate-Control and HVAC Module
The TLE7257SJXUMA1 can serve as the LIN physical-layer interface in an HVAC control module that distributes commands to temperature, fan, flap, and sensor nodes. The verified 20 kbps capability accommodates the modest payload rates associated with environmental control and diagnostic messaging, while the integrated regulator, wake-up support, and bus protection simplify implementation in a harsh vehicle environment. The device's listed AEC-Q100 status and -40 °C to +150 °C operating range are useful attributes for automotive assessment. Because LIN timing, dominant-state behavior, sleep currents, and supply boundaries are not present in the supplied verified data, engineers should verify them directly before selecting external passives or software timing.
Recommandé
Automotive Lighting Controller
The TLE7257SJXUMA1 is applicable in an automotive lighting controller that uses LIN-connected lamp drivers or external switch modules. Its 20 kbps LIN rate is adequate for switching commands, status feedback, and fault information rather than high-bandwidth payload transfer. The integrated regulator and protection features can help organize the transceiver supply, while wake-up capability supports systems that must remain responsive without maintaining a continuously active node. The compact PG-DSO-8 package is appropriate for dense electronic lighting modules. Before layout release, confirm the device's pin-level LIN implementation, regulator output, supply limits, and wake-up configuration against the official Infineon documentation.
Recommandé
Automotive Sensor and Actuator Hub
The TLE7257SJXUMA1 works as the bus interface for a small sensor or actuator hub that exchanges measurements and commands over a LIN branch. Its confirmed 20 kbps maximum rate is well suited to temperature, position, pressure, and switch-state information, and the integrated wake-up function can support low-power nodes. Bus protection is especially relevant where long harness branches may expose the transceiver to electrical transients or wiring faults. The device is listed for AEC-Q100 automotive applications and specifies an operating range of -40 °C to +150 °C. Exact transceiver input levels, output-current limits, and sleep behavior must still be confirmed from the manufacturer datasheet before the node is released for production.
Recommandé
Low-Speed Vehicle Network Gateway
The TLE7257SJXUMA1 can be used in a vehicle-network gateway or LIN-to-other-bus bridge when a controller must terminate a LIN segment and exchange messages with a higher-level network. The 20 kbps rate reflects the intended role of LIN as a low-cost complement to CAN and other vehicle buses rather than a replacement for them. The transceiver's integrated regulator, wake-up support, and protection features help implement a robust branch interface, while PG-DSO-8 packaging simplifies compact gateway boards. A gateway design must additionally handle LIN timing and fault recovery at the software layer. The supplied data does not specify detailed thresholds or current consumption, so those parameters must be checked before calculating termination, filtering, or power budgets.

Notes de conception
Route the LIN bus, supply, ground, and transceiver-control pins using the Infineon reference layout for PG-DSO-8. Keep the bus connection and its protection path compact, and place required input, output, and bypass capacitors directly at the associated pins. Confirm the exposed-pad connection and copper area from the official package drawing because the supplied verified results do not include a complete land pattern or pin table.
Separate the battery-side supply path from transceiver signaling and validate the regulator configuration against the official TLE7257SJ datasheet. The verified data confirms an integrated voltage regulator but does not state its output voltage or input limits. Do not calculate external component values or maximum dissipation until those specifications, the LIN transceiver output current, and the selected MCU supply requirements have been confirmed.
Do not treat ISO 17987-4 compliance, 20 kbps operation, and PG-DSO-8 packaging as sufficient proof of interchangeability. A replacement must also match wake-up polarity, sleep behavior, bus thresholds, receiver hysteresis, dominant-state timing, regulator output, and fault handling. Compare the official datasheets and qualify any substituted automotive device at the module level.
Keep sensitive communication and supply-return paths away from noisy switching nodes, motor drivers, relays, and inductive loads. Use a continuous ground reference beneath the transceiver and route the LIN connection away from high-current switching paths. Since the supplied information does not specify external pull-up values or protection-component requirements, use the manufacturer application guidance rather than generic LIN values.
Informations de conformité
AEC-Q100 automotive qualification is explicitly stated in the verified Arrow listing. RoHS, REACH, lead-free, halogen-free, and conflict-minerals status were not included in the supplied verified data.
