TLE7251VSJXUMA1 - 2Mbps CAN Transceiver | Infineon

Automotive Body Control Module

The TLE7251VSJXUMA1 fits an automotive body controller because it combines a 2 Mbit/s CAN data rate with operation from -40°C to +150°C and AEC-Q100 qualification. It connects the controller's CAN logic interface to the vehicle's differential CANH and CANL network, providing one transmitter and one receiver in an 8-pin PG-DSO-8 package. Low electromagnetic emissions and robust EMI and ESD protection are valuable in an environment containing many switching loads and interconnected ECUs. The exact-MPN supply range of 4.5 V to 5.5 V means the surrounding regulator must maintain a compliant 5 V rail. Board design should follow the manufacturer application circuit, preserve bus routing geometry, and include the required termination and common-mode interface components.

Vehicle Gateway Controller

A vehicle gateway can use the TLE7251VSJXUMA1 as the physical-layer interface between a CAN controller and an external CAN network segment. Its 2 Mbit/s capability supports high-speed CAN communication, while the single-transmitter and single-receiver arrangement provides one complete CAN node for a conventional controller channel. The PG-DSO-8 package supports compact PCB layouts, and the -40°C to +150°C range covers harsh vehicle temperature conditions. EMI performance is particularly important where the gateway links separate electrical domains and long harness runs. Place the transceiver near the connector or protected bus-entry region, keep CAN routing away from sensitive clock and sensor lines, and validate the completed module against the applicable automotive transient and EMC requirements.

Industrial CAN Sensor Node

The TLE7251VSJXUMA1 is suitable for an industrial sensor node that must communicate through a standard CAN bus. Its ISO 11898-2 compliance and 2 Mbit/s data rate provide a defined physical-layer interface, while the 4.5 V to 5.5 V supply range supports regulated 5 V sensor platforms. The wide -40°C to +150°C operating range also allows use in temperature-controlled cabinets, machinery, and industrial vehicles near heat-generating equipment. Because the device is not a CAN protocol controller, the host processor must handle frame construction, arbitration, error management, and bus-off recovery. The PCB should use a solid ground reference, controlled bus geometry, and the protection network recommended by the manufacturer for the target installation environment.

Infotainment CAN Interface

The TLE7251VSJXUMA1 can provide a high-speed physical interface for an infotainment or comfort-system controller operating on an automotive CAN network. Its 2 Mbit/s rate supports efficient communication with audio, climate, lighting, and vehicle-status nodes, while the small 8-pin DSO package helps satisfy compact board-space requirements. The transceiver's low electromagnetic emissions reduce coupling into nearby display, audio, and RF circuits, while EMI and ESD protection improve interface robustness. A system integrator must still account for the vehicle harness, bus topology, termination, and external protection devices. Maintain a continuous ground return near the CAN interface and route CANH and CANL as a tightly coupled differential pair to preserve signal quality in electrically noisy environments.

LED and Lighting Controller

The TLE7251VSJXUMA1 fits a CAN-linked lighting controller that receives commands and reports operating status over a vehicle network. The transceiver's 2 Mbit/s rate supports responsive communication, and its -40°C to +150°C rating is appropriate for electronics installed near lamps, relays, and other thermally variable locations. Robust EMI and ESD protection helps the controller interface withstand the electrical environment created by switched inductive loads. The 4.5 V to 5.5 V supply requirement should be met with a regulator capable of maintaining the specified range throughout vehicle transients. Place the interface close to the bus connector or harness entry point, use the manufacturer's recommended protection components, and keep switching-current paths separate from the CAN and logic grounds.

CAN Communication Test Module

A portable CAN test module can use the TLE7251VSJXUMA1 to provide a standardized physical-layer endpoint for diagnostics, bus monitoring, and firmware testing. ISO 11898-2 compliance and a 2 Mbit/s data rate support communication with common CAN systems, while the receiver's 90 mV hysteresis helps distinguish valid logic states. The PG-DSO-8 package is practical for compact measurement equipment, and the wide operating-temperature range supports industrial and automotive field use. The test module must pair the transceiver with a CAN controller capable of protocol and fault handling. Use a stable 5 V source, controlled termination for each test configuration, and shielded or protected external connectors. Validate the assembled tester against the target network because transceivers alone do not define termination or complete bus fault recovery.
