MPN： TLE7251VSJXUMA1 ✗ 停產TLE7251VSJXUMA1 概覽
A CAN transceiver, also called a CAN interface controller or CAN physical-layer transceiver, connects a host controller or microcontroller to the differential CAN bus. It converts digital logic-level TXD and RXD signals into the physical bus voltage and converts received bus states back into a logic-level signal. Within the interface hierarchy, this device sits between a CAN protocol controller and the CAN bus network.
Principal characteristics include ISO 11898-2 compliance, a 2 Mbit/s data rate, low electromagnetic emissions, robust electromagnetic-interference and electrostatic-discharge protection, and a 90 mV receiver hysteresis. The operating supply current is listed as 2.6 mA in one operating condition and up to 38 mA in another, allowing the distinction between normal operation and a higher-current condition to be checked in the manufacturer datasheet.
The automotive-grade temperature qualification and 8-pin DSO package make the transceiver suitable for compact vehicle-network electronics, including body controllers, gateways, infotainment modules, seat and door controllers, lighting controllers, and sensor nodes. Its ISO 11898-2 compatibility and high operating data rate also support industrial CAN systems requiring a standardized physical layer.
Designers should provide a stable 5 V rail within the 4.5 V to 5.5 V range, connect CANH and CANL to the network through the application-appropriate bus interface, and verify termination and common-mode behavior. The high ambient-temperature capability does not remove the need to control package dissipation and board-level thermal exposure.
This product page combines the manufacturer specifications, ordering information, lifecycle indication, package details, and application guidance into an engineering-focused reference. It also distinguishes documented drop-in migration options from devices that require different pin logic, supply requirements, or protection features.

典型應用
TLE7251VSJXUMA1 適用於 6 應用s: Automotive Body Control Module, Vehicle Gateway Controller, Industrial CAN Sensor Node, Infotainment CAN Interface, LED and Lighting Controller, CAN Communication Test Module.
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.
推薦
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.
推薦
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.
推薦
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.
推薦
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.
推薦
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.

設計說明
Route CANH and CANL as a closely coupled differential pair on the PCB and minimize stub branches, test pads, and unnecessary vias. Place the transceiver near the connector or protected bus-entry region, and keep the path between the transceiver and external protection network short. Maintain a low-impedance ground reference beneath the interface so common-mode and radiated-emissions performance is not degraded by excessive return-current loops.
Provide a regulated supply within the 4.5 V to 5.5 V range and decouple the transceiver supply pins according to the manufacturer application circuit. Place the closest high-frequency bypass capacitor directly at the device supply and ground pins, then add the recommended bulk capacitance near the power entry point. Confirm operation across vehicle or industrial supply transients because a nominal 5 V rail alone does not establish transient compliance.
Do not treat a CAN transceiver as a complete CAN controller: protocol handling, arbitration, error counters, and bus-off recovery remain the controller's responsibility. Verify enable and standby logic, receiver hysteresis, protection thresholds, and standby current before replacing another device. The TJA1050 and TJA1042 are not direct substitutes for this exact ordering code because their enable logic, supply requirements, and protection features differ.
Although the TLE7251VSJXUMA1 is rated from -40°C to +150°C, evaluate actual dissipation using the maximum operating current of 38 mA and the voltage difference between the supply and device requirements. Ensure the PG-DSO-8 package is soldered to an uninterrupted ground pad and adequate copper area. Derive junction temperature from the manufacturer thermal model rather than assuming that the ambient rating alone guarantees safe operation.
合規資訊
AEC-Q100 qualification is identified in product information. The exact-MPN listing states REACH Unaffected, but the visible RoHS text does not establish a definitive compliance value.
