TLE7251VLEXUMA1 - 2Mbps Automotive CAN Transceiver | Infineon
料号： TLE7251VLEXUMA1 ✓ 量产中TLE7251VLEXUMA1 概述
A CAN transceiver is an interface IC that connects a host controller or microcontroller to a Controller Area Network bus. It converts logic-level TXD and RXD signals into the differential CANH and CANL bus waveform and receives the bus state back to the controller. This makes the device part of the broader hierarchy of CAN interface ICs, bus transceivers, wired network interface semiconductors, and automotive communication electronics.
The TLE7251VLEXUMA1 is identified as an automotive-grade, 2 Mbps CAN transceiver with low electromagnetic emissions. It is intended for high-speed CAN networks in passenger vehicles and related embedded systems where deterministic communication, compact PCB area, and automotive qualification are important. The 1/1 channel arrangement allows the device to service one CAN bus channel while keeping the external interface compact.
The 8-pin PG-TSON-8-1 construction provides a small PCB footprint and an exposed thermal pad that supports heat transfer to the board. The exact exposed-pad dimensions, absolute maximum ratings, loop-delay limits, bus-fault behavior, and recommended external-component values should be confirmed against the Infineon manufacturer datasheet before schematic release or production qualification.
Typical uses include body-control modules, powertrain interfaces, comfort systems, automotive gateways, sensor nodes, and electronic control units. In these systems, the transceiver translates controller logic into CAN bus signals and returns the received bus state, allowing distributed vehicle functions to exchange data reliably over a shared differential network.
When laying out the PCB, place the transceiver close to the CAN bus connector and route CANH and CANL as a compact differential pair with continuous reference-plane support. Keep the CAN bus path away from clocks, switching power converters, and high-current motor or relay paths. Confirm the device's bus termination, common-mode, ground, and decoupling requirements using the manufacturer datasheet and the CAN transceiver reference circuit.
This product page organizes the device's automotive CAN interface characteristics, package information, design considerations, application guidance, and drop-in replacement assessment for faster engineering evaluation and BOM review.

典型应用
TLE7251VLEXUMA1 适用于 6 应用s: Automotive Body Control Module, Vehicle Sensor Node, Powertrain and Chassis ECU, Automotive Gateway, Industrial CAN Test Equipment, Battery-Powered Automotive Telemetry Unit.
Automotive Body Control Module
The TLE7251VLEXUMA1 fits an automotive body-control module that needs one high-speed CAN channel for exchanging switch, lighting, door, and sensor status. Its 2 Mbit/s capability accommodates a high-speed CAN network, while the 3.3 V or 5 V supply compatibility supports both common automotive logic environments. Place the 8-pin PG-TSON-8-1 device beside the CAN connector and route CANH and CANL as a controlled differential pair. The exposed pad supports board-level heat transfer, although thermal performance depends on the PCB copper area and the transceiver's operating duty cycle. Final qualification should verify temperature range, transient immunity, bus-fault behavior, and EMC performance for the target vehicle.
推荐
Vehicle Sensor Node
The TLE7251VLEXUMA1 can connect a distributed vehicle sensor node to an ISO 11898-2 high-speed CAN backbone. A node may acquire pressure, temperature, or position data locally and transmit it through the vehicle network, while receiving configuration or diagnostic commands. The single-channel 1/1 architecture minimizes board area, and the 2 Mbit/s bus rate supports efficient communication among multiple ECUs. Because the sensor node may be remote from the central harness, place the transceiver near the connector and provide the protection required by the vehicle network architecture. Review sleep current, wakeup behavior, standby current, and bus fault tolerance in the manufacturer documentation before choosing it for a low-energy node.
推荐
Powertrain and Chassis ECU
The TLE7251VLEXUMA1 is suitable for a powertrain or chassis electronic control unit that participates in a high-speed CAN network carrying torque, brake, steering, or transmission data. Its 2 Mbit/s support meets the stated operating class for the CAN physical layer, while AEC-Q100 identification supports automotive qualification workflows. The small 8-pin PG-TSON-8-1 package preserves board area in compact control modules. Thermal and EMC design remain critical because these modules operate near power-conversion hardware and electrically noisy harnesses. Use a short differential bus route, maintain a continuous ground reference, and follow the manufacturer reference circuit for decoupling and connector protection. Validate all transient, temperature, and fault requirements on the target platform.
推荐
Automotive Gateway
The TLE7251VLEXUMA1 can serve as one physical-layer interface within an automotive gateway that bridges vehicle network domains and exchanges diagnostic data. Its 1/1 transceiver arrangement allows a gateway channel to be assigned to a dedicated CAN network without introducing a multi-channel package. The 2 Mbit/s speed and ISO 11898-2 positioning align it with high-speed CAN segments rather than low-speed body networks. In a multi-channel gateway, repeat the recommended bus-routing and decoupling practices for each channel and maintain clear separation between CAN routing and high-speed processor or power-conversion circuitry. The device's automotive qualification and compact exposed-pad package are valuable when the gateway must satisfy space and reliability constraints, but system EMC validation remains required.
推荐
Industrial CAN Test Equipment
The TLE7251VLEXUMA1 can be used in industrial CAN test equipment or diagnostic hardware that must connect to a 3.3 V or 5 V controller and exchange messages on an ISO 11898-2 network. Its 2 Mbit/s capability provides useful bandwidth for traffic generation, bus monitoring, and firmware update routines. The 8-pin surface-mount package also supports compact multi-channel test hardware when several instrument boards are assembled. Designers should keep the CAN differential pair short, provide stable reference ground, and isolate test-harness transients with the protection network specified for the application. Although the device is automotive qualified, industrial use still requires verification of temperature, ESD, EMC, and bus-loading requirements against the intended test environment.
推荐
Battery-Powered Automotive Telemetry Unit
The TLE7251VLEXUMA1 can fit a battery-powered automotive telemetry unit that reports vehicle operating information over a high-speed CAN network. A single 1/1 transceiver channel provides the physical interface while the 3.3 V or 5 V supply option aligns with common automotive electronics. Its compact PG-TSON-8-1 footprint supports space-constrained installations, and the exposed pad can dissipate heat into the PCB when the copper area is designed correctly. For low-power operation, use the transceiver's power-down capability where supported by the complete operating profile and confirm wakeup timing in the manufacturer documentation. Care must be taken to prevent conducted noise from entering the CAN lines and to avoid excessive quiescent current in long-duration parking modes.

设计说明
Place the TLE7251VLEXUMA1 close to the CAN connector or termination network, and route CANH and CANL as a short differential pair over a continuous ground plane. Avoid stubs, layer changes, and splits beneath the pair. Keep the bus path separated from switching-regulator outputs, crystal clocks, relay contacts, and high-current motor wiring because these sources can couple displacement current into the sensitive differential thresholds.
Do not assume that a device marked CAN can replace a CAN FD transceiver. The TLE7251VLEXUMA1 is specified for the high-speed classical CAN application up to 2 Mbit/s. Also avoid adding termination at every CAN node: two 120-ohm terminators are normally placed at the physical ends of the bus. Confirm termination values, stub length, common-mode choke selection, and protection components against the Infineon reference circuit.
The PG-TSON-8-1 package includes an exposed pad for heat transfer into the PCB. Follow the manufacturer land-pattern and thermal-land guidance, maintain solder coverage compatible with assembly requirements, and connect the pad to the appropriate ground reference. Thermal performance depends on copper area, adjacent heat sources, airflow, and board construction, so validate the final ECU enclosure and operating temperature rather than relying on package type alone.
Use the manufacturer-recommended input and output capacitors at the device pins, with short ground returns and placed to minimize loop area. Size the supply network for normal communication, dominant-bus states, transient events, and any power-down or wake-up sequence. The device supports 3.3 V or 5 V operation, but the selected supply must remain within the complete electrical limits stated in the manufacturer datasheet.
