TLE7250XSJXUMA1 - 2Mbps CAN Transceiver | Infineon
料号： TLE7250XSJXUMA1 ✓ 量产中TLE7250XSJXUMA1 概述
A CAN transceiver is the physical-layer interface between a CAN controller and a differential CAN bus. It converts controller-side logic signals into balanced bus signals, receives bus states as digital logic, and provides galvanic isolation from the noisy vehicle network. Within the hierarchy of CAN interface ICs, transceiver ICs connect a digital controller or microcontroller to the CAN physical bus while handling bus-level signaling and fault conditions.
The TLE7250XSJ supports data rates up to 2 Mbit/s, ISO 11898-2 compatibility, low electromagnetic emissions, and strong ESD immunity. Its Infineon Smart Power Technology is AEC qualified for automotive applications. The PG-DSO-8 package is RoHS compliant and halogen free, and the leadless TSON-8 variant supports solder-joint inspection requirements for automated optical inspection.
The transceiver architecture supports both 3.3 V and 5 V controller-side operation, making it suitable for mixed-voltage automotive electronics. Its low-EMI behavior helps reduce interference with nearby RF, sensor, and infotainment circuits, while its ESD immunity supports reliable communication in electrically harsh environments. Design decisions should account for bus termination, common-mode voltage limits, supply decoupling, and transceiver-mode control.
Typical applications include automotive body-control modules, electric-window controllers, seat and climate-control electronics, instrument-cluster nodes, gateway modules, and distributed sensor networks connected to a vehicle CAN backbone. The part is particularly appropriate where a controller needs robust 2 Mbit/s CAN communication in a compact surface-mount footprint.
For PCB implementation, place the transceiver and its decoupling capacitors close to the associated CAN controller. Keep the CANH and CANL routing short, controlled-impedance and appropriately spaced, while avoiding unnecessary stubs. Confirm termination placement and the selected operating mode against the Infineon datasheet and the vehicle network specification.

典型应用
TLE7250XSJXUMA1 适用于 6 应用s: Automotive Body Control Modules, Electric Vehicle Powertrain Controllers, In-Vehicle Sensor and Actuator Networks, Vehicle Gateway and Communication Modules, Diagnostic and Telematics Units, Industrial CAN Equipment.
Automotive Body Control Modules
TLE7250XSJXUMA1 fits body-control modules that exchange commands and sensor status over a vehicle CAN network. Its 2 Mbit/s capability supports high-speed controller-area network communication, while the 3.3 V or 5 V supply option accommodates common ECU logic levels. The device is AEC qualified and uses Infineon Smart Power Technology for strong ESD immunity, high electromagnetic immunity, and low emissions. In an ECU, the transceiver sits between the CAN controller and CANH/CANL bus, translating logic states into differential bus signaling. The PG-DSO-8 footprint supports compact surface-mount layouts, but designers should preserve adequate copper for thermal performance and verify decoupling near the supply pins.
推荐
Electric Vehicle Powertrain Controllers
TLE7250XSJXUMA1 is suitable for CAN communication in electric-vehicle powertrain and battery-management controllers. The 2 Mbit/s interface rate permits timely exchange of torque commands, operating status, and diagnostic information across a high-speed CAN network. Its 3.3 V/5 V operating range supports integration with mixed-voltage control electronics, while AEC qualification and robust immunity characteristics suit electrically demanding vehicle environments. The transceiver handles the physical CANH/CANL layer, allowing the controller-side logic to operate through a defined digital interface. Bus layout remains critical: maintain the specified differential spacing, minimize stubs, use the correct termination topology, and confirm common-mode limits against the vehicle network specification.
推荐
In-Vehicle Sensor and Actuator Networks
TLE7250XSJXUMA1 can connect distributed sensors and actuators to an in-vehicle CAN backbone. Its 2 Mbit/s maximum rate supports high-speed nodes, while low electromagnetic emissions help preserve the signal environment around sensitive sensor electronics. The transceiver's high electromagnetic immunity and ESD resilience are valuable in systems exposed to transient events from motors, relays, and switching loads. Use it where an automotive controller needs the standard half-transceiver function in a compact PG-DSO-8 footprint. The design must account for the logic-side supply, CAN bus common-mode range, termination, and transceiver-mode configuration. Avoid placing sensitive analog traces beneath the bus nodes or beside high-current switching paths.
推荐
Vehicle Gateway and Communication Modules
TLE7250XSJXUMA1 is appropriate for gateway modules that connect CAN segments or exchange data with body, chassis, and infotainment networks. The 2 Mbit/s data rate matches conventional high-speed CAN systems, while 3.3 V and 5 V operation provides flexibility alongside gateway processors and communication controllers. Low emissions are particularly useful in compact modules containing several clocked digital circuits. Place the transceiver close to the connector or bus-routing region, keep CANH and CANL traces short and controlled, and provide local supply bypassing. If the gateway supports isolated communication domains, include the isolation components in the signal and power-budget design rather than assuming a non-isolated transceiver is suitable for every section of the network.
推荐
Diagnostic and Telematics Units
TLE7250XSJXUMA1 can serve as the CAN physical interface in diagnostic hubs, telematics units, and service-interface modules. Its 2 Mbit/s capability supports firmware-update traffic, vehicle status reporting, and diagnostic exchanges on high-speed CAN networks. The 3.3 V/5 V supply range allows integration with both legacy 5 V logic and modern 3.3 V controllers, while AEC qualification and strong EMI immunity support vehicle deployment. A practical implementation places the transceiver near the CAN connector, separates it from switching regulators and high-current relays, and uses a stable reference-free clock or oscillator appropriate for the selected controller. Validate low-power and wake-up operation in the complete ECU because bus-management requirements differ between diagnostic and communication nodes.
推荐
Industrial CAN Equipment
TLE7250XSJXUMA1 can also be evaluated for industrial CAN equipment where an 8-pin high-speed transceiver, 3.3 V/5 V operation, and robust EMC behavior are useful. Its Infineon Smart Power Technology, originally developed for automotive conditions, provides a strong foundation for industrial controllers exposed to electrically noisy machinery. The 2 Mbit/s rate supports high-speed factory automation, motion-control, and equipment-monitoring networks. The design should still meet the applicable industrial isolation, surge, grounding, and environmental requirements. Use the CAN bus specification to determine termination and stub lengths, place the transceiver away from high-current switching nodes, and test radiated and conducted emissions in the final enclosure rather than relying only on component-level immunity claims.

设计说明
Route CANH and CANL as a closely coupled differential pair, maintain the spacing recommended by the Infineon TLE7250X application information, and minimize the distance from the transceiver to the bus connector or termination point. Avoid branch stubs because unequal stub lengths can alter edge behavior and reflections. Place the transceiver near the board edge when practical, while keeping switching-regulator and relay-current paths away from the bus nodes.
Place the required local bypass capacitors next to the transceiver supply pins and connect each ground reference directly to the appropriate ground plane with a short return path. Keep supply and ground connections narrow enough to control inductance but wide enough for the required current. The 3.3 V or 5 V capability does not remove the need to verify startup, power-down sequencing, and controller I/O thresholds in the complete ECU power architecture.
Do not select a replacement solely because the ordering code looks similar. Compare the TXD, RXD, enable or mode-control, ground, supply, CANH, and CANL functions, including input thresholds and inactive-state behavior. The Infineon TLE7250X datasheet should be consulted for each ordering variant because low-power, wake-up, standby, and fault-handling characteristics may differ even when the package and 2 Mbit/s data rate are unchanged.
Protect the CAN interface from conducted and radiated noise by separating it from motors, relay coils, inductive loads, and high-di/dt power paths. Use a continuous ground reference, avoid slots beneath the transceiver, and maintain return-current control beneath both logic and bus-side connections. Evaluate emissions and immunity in the complete vehicle or industrial enclosure because connector cables and neighboring controllers can materially affect system-level EMC performance.
