TLE6251DXUMA1 - 1 Mbps ISO 11898-2/-5 CAN Transceiver
Teilenummer: TLE6251DXUMA1 ✓ AktivTLE6251DXUMA1 Übersicht
A CAN transceiver, also called a CAN physical-layer interface, converts the logic-level transmit and receive signals of a CAN controller into the differential CANH and CANL bus signals. It also converts bus-level differential voltage back into a receive signal for the controller. Within the hierarchy of interface ICs, CAN transceivers sit between a digital protocol controller and the physical CAN network.
Key features include a maximum data rate of 1 Mbps, low electromagnetic emission, excellent ESD immunity, short-circuit protection against ground, battery, and VCC, and an extended supply range on VCC and VIO. A TxD time-out function provides an additional safeguard for applications that require the transmitter to return to a defined state. The low CAN-bus leakage current in power-down state supports reduced standby consumption.
The TLE6251DXUMA1 is designed for high-speed CAN networks in automotive and industrial control systems. Its ISO 11898-2 compatibility targets conventional high-speed CAN communication, while ISO 11898-5 compatibility extends support to systems using the low-speed fault-tolerant CAN variant. The separate VIO input allows the digital interface voltage to be selected independently from the transceiver's principal supply where the supported operating ranges permit it.
Typical applications include automotive body and powertrain control modules, industrial automation controllers, robot communication networks, diagnostic equipment, building automation systems, and distributed sensor nodes. The device is particularly relevant where a controller requires a robust physical-layer interface, EMI control, ESD resilience, and protection against accidental bus shorts.
Designers should confirm the supported transceiver-mode, supply, common-mode, and pin-level requirements in the manufacturer datasheet before layout release. CAN bus routing requires controlled impedance, appropriate termination, a common reference ground, and separation from noisy or high-current paths. The DSO package also requires careful thermal and assembly planning where the surrounding PCB provides limited copper area.
This page combines the verified manufacturer and distributor information with practical comparison guidance, application context, and design notes. It distinguishes documented TLE6251DXUMA1 characteristics from unverified parameters so procurement and engineering teams can identify missing datasheet data before committing a design to production.

Typische Anwendungen
TLE6251DXUMA1 ist geeignet für 6 Anwendungs: Automotive Body Control Module, Industrial Automation Controller, Robot Communication Network, Vehicle Diagnostic Gateway, Building Automation Node, Distributed Sensor Network.
Automotive Body Control Module
The TLE6251DXUMA1 fits an automotive body-control module that connects a CAN controller to a high-speed vehicle network. Its documented 1 Mbps capability, ISO 11898-2 and ISO 11898-5 support, very low electromagnetic emission, and excellent ESD immunity address the signal-integrity and robustness demands of a distributed vehicle network. The 4.5 V to 5.5 V principal supply supports regulated 5 V environments, while the VIO input can adapt the controller-facing interface to the local digital supply. Short-circuit protection against ground, battery, and VCC adds resilience during wiring faults. Final automotive use still requires confirmation of the exact order code's temperature grade and qualification status.
Empfohlen
Industrial Automation Controller
The TLE6251DXUMA1 is appropriate for an industrial automation controller that must bridge a microcontroller or programmable controller to a high-speed CAN fieldbus. The transceiver's 1 Mbps maximum rate allows it to participate in demanding factory-control networks, while its -5 V common-mode capability improves tolerance to electrically coupled industrial noise. Low EME helps prevent the CAN interface from disturbing adjacent control circuitry, and the short-circuit protections reduce risk during installation or field-wiring faults. The separate VIO input is useful when the controller operates from a supply different from the transceiver's principal 4.5 V to 5.5 V rail, subject to the manufacturer's permitted operating combinations.
Empfohlen
Robot Communication Network
The TLE6251DXUMA1 can serve as the physical-layer interface for robots that exchange commands, state, and sensor data over CAN. Its 1 Mbps capability supports high-speed communication where controller updates must be coordinated across multiple nodes. Low electromagnetic emission is valuable inside compact robot enclosures where CAN routing may run near motor drivers, while excellent ESD immunity helps protect the interface from handling and connection-related transients. Short-circuit protection to ground, battery, and VCC improves robustness against field wiring mistakes. The TLE6251DXUMA1 should be paired with correctly terminated CANH and CANL routing and a verified ground reference to obtain reliable network performance.
Empfohlen
Vehicle Diagnostic Gateway
A diagnostic gateway can use the TLE6251DXUMA1 to connect a vehicle network segment to another controller or diagnostic processor. Its high-speed CAN operation, ISO 11898-2 and ISO 11898-5 support, and 1 Mbps capability suit communication-intensive automotive networks. The -5 V common-mode range increases tolerance to transients and voltage offsets encountered in connected vehicle systems, while low EME limits unwanted coupling into nearby electronics. The VIO input supports adaptation to the gateway processor's digital supply, and the short-circuit protections improve behavior during installation or harness faults. Engineers must verify the exact qualification, temperature, and ordering-code details before production release.
Empfohlen
Building Automation Node
The TLE6251DXUMA1 is suitable for a building-automation node that distributes sensor, actuator, and supervisory information over a CAN bus. The 4.5 V to 5.5 V operating supply is compatible with common regulated industrial rails, and the VIO input permits interface-level adaptation to the node controller. Very low electromagnetic emission is beneficial in control cabinets containing switching power converters, relays, and long wiring runs. Excellent ESD immunity and short-circuit protection improve robustness at externally accessible terminals. The implementation should still observe normal CAN practice, including 120-ohm termination at appropriate bus ends, controlled pair routing, adequate ground bonding, and validation of the selected ISO 11898-2 or ISO 11898-5 network mode.
Empfohlen
Distributed Sensor Network
The TLE6251DXUMA1 can interface distributed sensor nodes to a central CAN acquisition controller. A 1 Mbps physical layer supports timely collection of measurements from multiple remote nodes, while low power-down bus leakage helps limit standing current in inactive branches. The VIO input is useful in mixed-voltage embedded systems because the controller-facing supply can be adapted independently of the principal 4.5 V to 5.5 V transceiver supply. Low EME reduces coupling back into sensitive sensor circuitry, and ESD immunity provides additional protection for cabling that leaves a control enclosure. Network timing, termination, common-mode behavior, and standby-state requirements must be validated together for the final sensor topology.

Wichtigste Unterscheidungsmerkmale
- Supports both high-speed and fault-tolerant CAN standards (vs. TLE6251DXUMA2)
- Digital supply adaptation through VIO (vs. TLE6251DXUMA2)
- Documented low-noise and fault-resistant bus behavior (vs. TLE6251DXUMA2)
Designhinweise
Route CANH and CANL as a tightly coupled differential pair on the same PCB layer, using the longest practical straight sections and minimizing stubs, vias, and discontinuities. Keep the pair away from switching nodes, high-current returns, and crystals. Where the transceiver is exposed through a connector, add a properly designed protection network and confirm its capacitance does not compromise the 1 Mbps target; the verified source does not supply component-level recommendations.
Decouple VCC and VIO locally at the device pins according to the manufacturer datasheet. Keep the CAN transceiver's supply return continuous and low impedance because common-mode and conducted-immunity performance depend on a stable reference. The verified material confirms 4.5 V to 5.5 V principal operation and a VIO adaptation input, but it does not publish capacitor values, current limits, or startup timing; these must not be guessed.
Do not treat the TLE6251DXUMA1 as a generic CAN transceiver without checking its supported operating mode. ISO 11898-2 high-speed CAN and ISO 11898-5 fault-tolerant CAN have different topology and timing expectations. Also verify the exact pins, standby behavior, wake-up function, qualification, and electrical limits from the official TLE6251D documentation before assigning PCB nets or approving a substitute.
Place the transceiver close to the CAN connector or bus entry point to minimize unprotected trace length. Provide a solid ground-plane return beneath the CAN pair, avoid placing ground splits under the interface, and maintain the bus geometry through connectors and test points. Termination belongs at the physical ends of the bus rather than at every node, and engineers should verify whether any onboard termination must be enabled or removed during testing.
Compliance-Informationen
The verified Digi Electronics listing states RoHS3 compliant. No exact-order-code evidence was supplied for REACH, lead-free status, halogen-free status, conflict minerals, or AEC-Q100 qualification. Automotive-family suitability is indicated by Infineon product information, but the exact ordering-code qualification is [DATA_NEEDED].
