TLE7250LEXUMA1 - 1 Mbps Automotive CAN Transceiver | Infineon
N.º de pieza: TLE7250LEXUMA1 ✓ ActivoTLE7250LEXUMA1 Descripción general
A CAN transceiver, also called a CAN interface IC or physical-layer transceiver, connects a CAN protocol controller to the differential CAN bus. It converts controller logic signals into CAN bus levels, receives bus signals, and provides the interface between the digital controller domain and the physical vehicle or industrial network. The TLE7250LE family is designed for automotive and industrial HS CAN networks and supports ISO 11898-2 operation.
The TLE7250LEXUMA1 provides one transceiver channel and is identified as a 1/1 transceiver in the product listing. Its principal operating specifications include a 5 V supply and a 1 Mbit/s classical CAN data rate. Infineon identifies the device as an automotive CAN transceiver with AEC-Q100 qualification, while the family documentation describes CAN FD support up to 2 Mbit/s and low electromagnetic emission and immunity characteristics.
The device is intended to be placed between a CAN protocol controller and the physical CAN_H and CAN_L bus conductors. Its bus interface protects the controller from interference generated within the network, while its receive path presents the bus state to the controller. Because it is a physical-layer device rather than a complete CAN controller, it requires a separate CAN protocol controller, an appropriate bus termination arrangement, and a correctly designed CAN bus harness.
Typical applications include automotive body-control modules, gateway units, comfort systems, engine-control electronics, industrial automation equipment, and other embedded CAN nodes. For 1 Mbit/s designs, the family data-rate rating and ISO 11898-2 compatibility are central selection criteria. Systems operating above the classical CAN limit should verify the complete CAN FD controller, bus timing, transceiver operating mode, and network topology.
A robust PCB layout should provide a short, symmetric route between the transceiver and CAN bus connector, maintain the bus differential impedance specified by the system, and minimize the loop area of CAN_H and CAN_L. Keep sensitive controller and reference circuitry away from the bus traces, provide the required bypass capacitance at the device, and use the exposed-pad land pattern for effective thermal dissipation.
This page consolidates the verified product identity, package information, automotive qualification, CAN capability, application guidance, and drop-in assessment into one engineering-focused view. It also distinguishes confirmed characteristics from parameters that require consultation of the current Infineon datasheet before layout release or production qualification.

Aplicaciones típicas
TLE7250LEXUMA1 es adecuado para 6 aplicacións: Automotive Body Control Module, Automotive Gateway Controller, Engine Control Electronics, Industrial Automation Controller, Vehicle Comfort System ECU, Embedded CAN Sensor Node.
Automotive Body Control Module
The TLE7250LEXUMA1 fits an automotive body-control module that connects a CAN protocol controller to a vehicle network. Its 5 V supply, ISO 11898-2 physical-layer support, and 1 Mbit/s maximum classical CAN rate align with conventional automotive CAN links, while CAN FD capability up to 2 Mbit/s provides additional design headroom. The interface converts controller signals to differential bus levels and receives bus activity for the controller. Place the device close to the connector or harness branch, follow the exposed-pad thermal land pattern, and verify temperature grade, ESD behavior, and fault-mode requirements for the vehicle platform before production release.
Recomendado
Automotive Gateway Controller
A gateway controller commonly connects separate CAN domains, making transceiver signal integrity and interface protection important. The TLE7250LEXUMA1 provides one half-duplex physical-layer channel with a 1 Mbit/s classical CAN rating, CAN FD operation up to 2 Mbit/s, and a 5 V supply that supports integration with automotive controller electronics. The transceiver operates between the CAN protocol controller and differential CAN_H and CAN_L conductors, helping protect the controller from network-generated interference. For a gateway PCB, minimize the differential trace separation from the transceiver to the bus connector, provide clean ground return, and confirm timing and fault behavior in the complete network configuration.
Recomendado
Engine Control Electronics
The TLE7250LEXUMA1 is suitable for engine-control electronics requiring an Infineon automotive CAN interface. Its 1 Mbit/s maximum classical CAN data rate supports established vehicle networks, while the documented CAN FD capability of up to 2 Mbit/s can assist future designs that use higher-rate CAN FD traffic. The device operates from 5 V and provides the physical bus interface expected by a separate CAN protocol controller. Use an exposed-pad layout that minimizes thermal resistance, keep switching and high-current paths away from the CAN interface area, and validate the exact temperature range, transient response, common-mode limits, and diagnostic behavior on the target power architecture.
Recomendado
Industrial Automation Controller
The TLE7250LEXUMA1 can interface industrial automation equipment using an ISO 11898-2 high-speed CAN network. Its 5 V supply, one-channel half-duplex architecture, and 1 Mbit/s classical CAN rate fit compact PLCs, machine controllers, and factory communication modules. The CAN FD capability up to 2 Mbit/s is useful only when the controller, bus timing, cable characteristics, and all connected nodes support the higher rate. Keep the CAN_H and CAN_L route as a controlled differential pair, apply the termination scheme required by the bus topology, and use the exposed thermal pad and bypass layout specified by the manufacturer datasheet.
Recomendado
Vehicle Comfort System ECU
Body, climate, seating, and lighting comfort systems commonly use CAN links to exchange commands and sensor information. The TLE7250LEXUMA1 provides the differential physical-layer interface between such an electronic control unit and its CAN protocol controller. Its automotive AEC-Q100 designation supports the automotive context, while the 5 V supply and 1 Mbit/s classical CAN capability align with established in-vehicle networks. The half-duplex arrangement also helps reduce the component and wiring burden for one-channel nodes. Verify wake, standby, and sleep requirements if the ECU uses low-power operating modes, and follow the manufacturer pin and thermal-land instructions rather than relying on a generic TSON footprint.
Recomendado
Embedded CAN Sensor Node
The TLE7250LEXUMA1 can serve as the bus interface in an embedded sensor or actuator node that reports measurements to a CAN controller. Its one-channel, half-duplex configuration suits nodes with one physical CAN segment, and the 1 Mbit/s classical CAN rating accommodates common industrial and vehicle network speeds. The transceiver provides the physical-layer path while the separate controller handles arbitration, framing, error management, and diagnostics. Design the PCB with a short bus connection, controlled differential routing, solid ground continuity, and decoupling near the 5 V supply pins. Before deployment, verify the supported node count, bus common-mode range, ESD immunity, and behavior during bus faults against the operating environment.

- Compact exposed-pad implementation (frente a TLE7257SJXUMA1)
Notas de diseño
Route CAN_H and CAN_L as a controlled differential pair from the transceiver to the bus connector. Minimize branch stubs and keep the pair length balanced. Place termination only at locations defined by the network topology; incorrect termination can load the bus and impair communication at the device's 1 Mbit/s classical CAN capability.
Implement the exposed pad using the manufacturer's PG-TSON-8-1 land pattern and an adequate ground plane. The pad provides the primary thermal path from the device, so avoid cutting it away with isolated board-routing rules. Confirm actual junction temperature and copper area with the thermal information in the current Infineon datasheet before finalizing the board.
Do not treat the transceiver as a complete CAN controller. A compatible CAN protocol controller is required for arbitration, framing, acknowledgements, error handling, and diagnostics. Also verify that 5 V supply tolerances, transceiver mode settings, bus common-mode range, and the controller's CAN FD capability agree before enabling operation above 1 Mbit/s.
Keep the CAN interface physically separated from noisy power-conversion stages and high-speed digital clocks. Use a continuous ground reference and short supply-decoupling path. Infineon describes the TLE7250LE family as having low EME/EMI characteristics, but system-level electromagnetic performance still depends on PCB layout, harness construction, filtering, and the chosen bus topology.
