TLE8251VSJXUMA1 - 2Mbps CAN Transceiver | Infineon
料号： TLE8251VSJXUMA1 ✓ 量产中TLE8251VSJXUMA1 概述
A CAN transceiver is a physical-layer interface within a controller-area network. It converts logic-level TXD and RXD signals into the differential CAN bus levels used by connected nodes and receives those bus levels back as a logic signal for the CAN protocol controller. In the OSI hierarchy, the TLE8251VSJXUMA1 occupies the physical layer, while the CAN controller handles frames, arbitration, error management, and higher-layer communication.
The headline capabilities are a maximum CAN data rate of 2 Mbps, a single-channel transceiver arrangement, integrated bus wake-up support, and an 8-pin PG-DSO-8 surface-mount package. These features suit compact automotive electronic control units, industrial automation equipment, and distributed control systems that require a dependable connection between a CAN controller and a twisted-pair network. The automotive-grade temperature capability supports use in demanding vehicle electronics environments.
The transceiver isolates the CAN controller's digital interface from the physical bus while adding the electrical behavior needed for robust communication. Bus wake-up reduces the need for the host controller to remain fully active when communication is intermittent. Its 2 Mbps capability also provides useful bandwidth compared with slower CAN nodes, while remaining compatible with the HS CAN network architecture described in the manufacturer documentation.
Typical applications include body-control modules, powertrain-related controllers, sensor gateways, industrial motor controllers, factory automation nodes, and industrial Ethernet-to-CAN gateways. The device is especially relevant when a controller exposes a CAN host interface and the PCB has a PG-DSO-8 land pattern compatible with the device's pin configuration.
For layout, place the transceiver close to the CAN connector and maintain a short, direct CANH and CANL path. Keep the bus-side return path continuous, provide the interface and biasing components recommended by the manufacturer, and verify that the controller voltage levels match the transceiver's digital interface.
This page consolidates the operating speed, bus-wake-up function, automotive temperature capability, package details, sourcing guidance, and practical integration considerations into one engineering-focused reference for evaluating TLE8251VSJXUMA1.

典型应用
TLE8251VSJXUMA1 适用于 6 应用s: Automotive Body Control Modules, Industrial CAN Sensor Gateway, Vehicle Network Interface, Motor Control and Automation Nodes, Distributed Control Systems, CAN-to-Ethernet Gateway.
Automotive Body Control Modules
The TLE8251VSJXUMA1 fits body-control modules that connect a CAN controller to door, lighting, climate, or seat modules. Its 2 Mbps maximum data rate accommodates high-speed CAN traffic, while the automotive-grade designation and 150 °C maximum operating temperature support demanding vehicle environments. Place the transceiver near the CAN connector, route CANH and CANL as a tightly coupled pair, and use the manufacturer application circuit for biasing and protection components.
推荐
Industrial CAN Sensor Gateway
The TLE8251VSJXUMA1 is useful in an industrial gateway that translates between a host processor and distributed CAN sensors. A 2 Mbps physical layer supports higher-volume traffic than 1 Mbps CAN links, and bus wake-up can reduce controller activity when the network is quiet. Validate propagation delay and bit timing at the maximum network length, provide proper termination, and include surge or common-mode protection based on the installation environment.
推荐
Vehicle Network Interface
In a vehicle network interface, the TLE8251VSJXUMA1 provides the physical-layer path between a CAN protocol controller and the vehicle's twisted-pair bus. The 1 TX and 1 RX channel arrangement supports a compact single-CAN node, while the 150 °C maximum operating temperature supports demanding locations. Keep the CAN bus traces short and away from clocks, switching regulators, and high-current motor paths to minimize electromagnetic coupling.
推荐
Motor Control and Automation Nodes
The TLE8251VSJXUMA1 supports CAN-connected motor-control and automation nodes that exchange commands and diagnostic information with a central controller. Its 2 Mbps capability allows the physical layer to serve high-speed CAN traffic while preserving the CAN controller's familiar host interface. The transceiver should be positioned near the bus connector, while logic and power routing remain separated from CANH and CANL to reduce susceptibility to industrial EMI.
推荐
Distributed Control Systems
The TLE8251VSJXUMA1 can serve as the CAN physical-layer interface in distributed industrial control systems where remote nodes must exchange process data with a supervisory controller. The 2 Mbps maximum rate provides useful bandwidth for synchronized control traffic, and bus wake-up helps manage intermittent communication. Engineers should calculate bit timing from the actual oscillator tolerance, network length, and transceiver delay, then test the system across startup and bus-fault conditions.
推荐
CAN-to-Ethernet Gateway
The TLE8251VSJXUMA1 fits the CAN side of a gateway connecting legacy CAN equipment to an Ethernet backbone. The 2 Mbps CAN rate supports efficient transfer of process and diagnostic data, while bus wake-up can help recover network nodes after an idle period. Use a controller with a proven CAN peripheral, isolate Ethernet routing from the bus side, and verify EMC performance with the enclosure, cable, connector, and protective network installed.

设计说明
Place the TLE8251VSJXUMA1 close to the CAN connector and route CANH and CANL as a short, tightly coupled differential pair. Keep the CAN-side ground return continuous and avoid sharing high-current return paths with the pair. Increase the separation from clocks, switching nodes, inductors, and display or motor-drive circuitry to reduce radiated emissions and susceptibility to conducted noise.
Do not assume that an 8-pin CAN transceiver is interchangeable solely because its package matches. Verify TXD and RXD pin positions, logic thresholds, supply range, standby current, wake-up timing, bus-bias behavior, data rate, and ESD rating. After substitution, recalculate the controller's bit timing for the transceiver's propagation delay and test dominant-to-recessive transitions with the final cable, termination, and network topology.
Separate the transceiver's supply routing from sensitive logic paths and place local bypass capacitance at the device's supply and ground pins. Use the manufacturer application circuit to select the biasing, termination, and protection components. Check startup sequencing, bus fault behavior, and supply tolerance because a robust CAN physical layer still depends on clean local power and correct component placement.
Treat CANH and CANL as a single high-frequency differential pair rather than independent nets. Avoid stubs, test pads, and unnecessary copper changes that create impedance discontinuities. Use the recommended termination strategy at the physical ends of the bus, and evaluate emissions and immunity in the finished enclosure because cable routing and protective components materially affect EMC performance.
