TLE6251DSXUMA2 - 1Mbaud CAN Transceiver | Infineon
料号： TLE6251DSXUMA2 ✓ 量产中TLE6251DSXUMA2 概述
A CAN transceiver, also called a CAN physical-layer interface, connects a host controller or microcontroller to the differential CANH and CANL bus conductors. It belongs to the physical-layer transceiver branch of CAN interface ICs, which convert logic-level TXD and RXD signals into robust differential bus signals and return received bus states to the controller. This interface layer is distinct from the CAN protocol controller, which handles frames, arbitration, acknowledgments, and error management.
The TLE6251DS provides 1 Mbaud operation, a 1/1 transmitter-to-receiver arrangement, full duplex operation, 200 mV receiver hysteresis, and an operating-voltage range of 4.75 V to 5.25 V. According to the supplied manufacturer and distributor information, the device also offers remote wake-up through the CAN bus while operating in low-power mode. This behavior supports partially unpowered nodes and mixed networks in which one node may be asleep while another remains active.
The TLE6251DS is described as the successor to the first-generation TLE6250 high-speed CAN transceiver. Infineon emphasizes excellent passive behavior when the transceiver is switched off, which is relevant to mixed networks and vehicle applications operating at terminal 15 or terminal 30. Distributor records also identify the device as an automotive CAN transceiver associated with AEC-Q100 qualification, making its operating-temperature range and interface characteristics suitable for demanding vehicle communication networks.
Typical uses include body electronics, powertrain-adjacent controllers, industrial automation equipment, vehicle diagnostic systems, distributed control modules, and CAN-based sensor or actuator networks. The 1 Mbaud data rate accommodates both lower-rate legacy CAN systems and conventional high-speed CAN communication. The 8-pin DSO package also permits a compact surface-mount implementation, although correct CAN bus termination, common-mode protection, and transient immunity remain essential board-level requirements.
Designers should preserve the recommended decoupling and transceiver connection layout, use an appropriate 120-ohm termination strategy at each network endpoint, and verify the logic-level interface and supply sequencing against the controller used in the design. The remote wake-up and low-power behavior are useful features, but a partially unpowered node still requires system-level validation for bus isolation, standby-state behavior, and recovery after power restoration.
This product record combines the verified manufacturer attributes, distributor availability, price, package information, and approved same-package cross-reference with practical selection and integration guidance. It highlights verified differences without presenting general-purpose interface ICs or package-changing alternatives as drop-in replacements.

典型应用
TLE6251DSXUMA2 适用于 6 应用s: Automotive Body Control Networks, Vehicle Diagnostic and Telemetry Modules, Industrial Automation CAN Systems, Mixed Networks with Partially Unpowered Nodes, Distributed Sensor and Actuator Networks, Powertrain-Adjacent Vehicle Communication.
Automotive Body Control Networks
The TLE6251DSXUMA2 fits body-control modules that exchange door, lighting, climate, and central-locking information over a high-speed CAN network. Its 1 Mbaud capability supports conventional high-speed CAN traffic, while the -40 °C to 150 °C operating range and AEC-Q100 listing from the supplied Newark record address automotive environmental requirements. The 8-pin PG-DSO-8 package keeps the physical-layer section compact. Designers should still verify transient immunity, bus fault behavior, and qualification at the complete module level rather than relying on the transceiver qualification alone.
推荐
Vehicle Diagnostic and Telemetry Modules
The TLE6251DSXUMA2 is appropriate for diagnostic adapters and telemetry modules that must remain reachable over a shared vehicle CAN network. Its remote wake-up capability allows a low-power node to be activated through bus activity, supporting systems with partially unpowered participants. The 5 V supply range of 4.75 V to 5.25 V must be reconciled with the module power architecture, while the 200 mV receiver hysteresis helps distinguish logic states from noise. In diagnostic designs, sleep and standby behavior should be tested with the selected controller and network wake-up logic.
推荐
Industrial Automation CAN Systems
The TLE6251DSXUMA2 can connect industrial controllers, remote I/O modules, drives, and sensors that use high-speed CAN. A 1 Mbaud rate accommodates common industrial CAN segmentation practices, while full-duplex operation and 200 mV receiver hysteresis support reliable logic interfacing. The operating-temperature range reaches 150 °C, providing margin for harsh installed equipment when the enclosure and system qualification support that condition. Proper termination, common-mode protection, and isolated or non-isolated grounding must be established for each bus topology.
推荐
Mixed Networks with Partially Unpowered Nodes
The TLE6251DSXUMA2 is specifically useful in mixed CAN networks where some nodes are powered down while others remain active. Infineon describes remote wake-up through the CAN bus in low-power mode and excellent passive behavior when the transceiver is switched off. These characteristics reduce the chance that a disabled node disturbs the active network and support terminal 15/30-style vehicle applications. A successful implementation must still verify that the attached controller handles wake-up requests correctly and that the inactive transceiver’s bus behavior satisfies the complete network specification.
推荐
Distributed Sensor and Actuator Networks
The TLE6251DSXUMA2 suits distributed CAN nodes that gather measurements or control actuators over a shared differential bus. Its 1 Mbaud rate provides a practical communication ceiling for sensor clusters and actuator gateways, while the 1/1 driver-receiver arrangement supports normal CAN physical-layer signaling. Compact PG-DSO-8 packaging leaves board area for the controller, power conversion, and protection components. Because several nodes may communicate simultaneously, designers should account for propagation delay, bus length, stub geometry, termination, and arbitration behavior.
推荐
Powertrain-Adjacent Vehicle Communication
The TLE6251DSXUMA2 can serve as the physical-layer interface in vehicle modules that communicate over high-speed CAN but do not necessarily connect directly to the powertrain controller. The -40 °C to 150 °C range and supplied AEC-Q100 association are relevant to demanding vehicle environments, while 1 Mbaud operation fits conventional vehicle CAN networks. The implementation must comply with Infineon’s recommended transceiver layout and local transient-protection requirements. Actual suitability for a safety- or powertrain-related position depends on the module’s own qualification and hazard assessment.

设计说明
Place the TLE6251DSXUMA2 in accordance with the manufacturer’s recommended transceiver layout, keeping the CANH and CANL paths short, symmetric, and away from sensitive analog or high-speed digital traces. Provide local supply decoupling at the device and route the ground return consistently with the chosen CAN interface implementation. The supplied data does not publish the exact capacitor values or routing dimensions, so these details should be taken from the current manufacturer datasheet rather than guessed.
Do not treat the similar TLE6251DS and TLE6251DSXUMA2 listings as evidence that every ordering suffix is interchangeable. The verified same-package cross-reference applies to TLE6251DSXUMA1, while TLE6251DXUMA2 appears in separate product records without a supplied pin-compatibility proof. Confirm the full orderable MPN, package drawing, exposed-pad or lead requirements, tape orientation, and approved-part status before substituting a suffix in a released design.
Operate the transceiver only within its verified 4.75 V to 5.25 V supply range. Provide adequate local decoupling and verify controller and transceiver power-up order so the TXD and enable-related states cannot create an unintended bus condition during startup. Because the available data identifies sleep and standby behavior but does not provide complete timing or logic thresholds, capture those values from the manufacturer datasheet and validate them with the chosen CAN controller.
Apply the correct bus termination strategy at the physical network endpoints and avoid unnecessary stubs, which can increase reflections and radiated emissions. For vehicle or industrial installations, add only protection devices that preserve CAN signal timing and current handling. The TLE6251DS’s passive off-state behavior supports mixed networks, but the complete network still requires EMC validation under its target load, cable length, protection scheme, and operating mode.
合规信息
The Newark distributor result identifies the TLE6251DSXUMA2 as an AEC-Q100 automotive CAN transceiver. The supplied data does not explicitly establish RoHS, REACH, lead-free, halogen-free, or conflict-minerals status, so those fields remain unknown.
