TLE9222LCXUMA1 Présentation
A FlexRay transceiver is a physical-layer (PHY) device that sits between a microcontroller's FlexRay Communication Controller and the differential FlexRay bus. It converts digital logic-level signals from the controller into differential bus voltages conforming to the FlexRay electrical specification, and vice versa for reception. The transceiver category sits within the broader automotive communication IC hierarchy of transceivers -> interface ICs -> integrated circuits. FlexRay was developed as a deterministic, fault-tolerant backbone for high-speed in-vehicle networking, supporting time-triggered and event-triggered communication with bandwidth up to 10 Mbit/s per channel.
Key features of the TLE9222LCXUMA1 include an integrated bus failure detection (open, short-to-GND, short-to-VBAT) with diagnostic output, low standby current consumption for battery-sensitive applications, and an extended automotive temperature operating range. The PG-TSON-14-3 package exposes a thermal pad to the PCB for efficient heat removal through the copper pours. The TLE9222LCXUMA1 part number suffix -XUMA1 indicates reel packaging for high-volume surface-mount assembly.
Typical applications for the TLE9222LCXUMA1 include electronic control units in chassis-by-wire systems (steering, braking, suspension), powertrain ECUs, ADAS sensor fusion controllers, and body-domain modules where deterministic, redundant communication is required. The combination of small package footprint, robust bus failure diagnostics, and low-power modes suits compact ECU designs where PCB area is at a premium.
When designing with this device, follow Infineon's recommended PCB layout for the exposed thermal pad and use a star-grounding scheme for the bus shield connection. Always consult the manufacturer datasheet for the latest bus failure threshold values and EMC optimization recommendations for the differential bus termination network.

Applications typiques
TLE9222LCXUMA1 convient pour 6 applications: Chassis-by-Wire ECU, Powertrain Domain Controller, ADAS Sensor Fusion ECU, Body Domain Module, Hybrid Drive Inverter ECU, Network Backbone Gateway.
Chassis-by-Wire ECU
The TLE9222LCXUMA1's FlexRay physical layer is engineered for chassis-by-wire ECUs in electric power steering, electronic stability control and active suspension systems. Its 10 Mbit/s bandwidth and deterministic time-triggered protocol meet the strict latency budgets required for safety-critical steering and braking functions, while the integrated bus failure diagnostics support ASIL-rated system decomposition. The PG-TSON-14-3 package (3.0 mm x 4.5 mm) fits directly inside compact steering-column modules and brake-by-wire actuators where PCB real estate is severely constrained. Combined with low standby current consumption, the part supports battery-saving sleep modes for parked vehicles. The differential BP/BM bus pins connect to the standard FlexRay twisted-pair backbone with EMC bus termination following Infineon's reference layout. Compared with CAN-FD transceivers used in older chassis ECUs, the TLE9222LCXUMA1 delivers 10x higher bandwidth, enabling faster sensor data fusion.

Powertrain Domain Controller
In powertrain ECUs (engine management, transmission control, electric drive controllers) the TLE9222LCXUMA1 provides the FlexRay physical layer connecting the host microcontroller to the vehicle's high-speed backbone. The part's -40 to +125 degrees C automotive temperature grade supports under-hood placement adjacent to power electronics, while integrated bus failure detection (open, short-to-GND, short-to-VBAT) enables robust fault handling on noisy powertrain buses. Its small PG-TSON-14-3 footprint allows integration into space-constrained transmission mechatronic units. The standby current consumption and remote wake-up feature minimize quiescent drain when the vehicle is parked. Bus-side protection meets automotive ESD and transient requirements specified in the Infineon datasheet. Compared with previous-generation FlexRay transceivers, the TLE9222LCXUMA1 reduces PCB area by roughly 50 percent while maintaining protocol compliance with ISO 17458.
Recommandé
ADAS Sensor Fusion ECU
Advanced driver-assistance systems (ADAS) require deterministic, high-bandwidth communication between perception sensors (radar, lidar, camera) and the central fusion ECU. The TLE9222LCXUMA1 enables this connectivity via its 10 Mbit/s FlexRay link, which carries object lists and fused track data with bounded latency. The integrated bus diagnostics support ASIL-B and ASIL-D decomposition for safety-critical sensor fusion, while the compact PG-TSON-14-3 package fits inside camera and radar modules where PCB area is severely limited. The exposed thermal pad efficiently removes heat dissipated during sustained bus activity. Compared with CAN-FD used in older ADAS systems, FlexRay provides the time-triggered deterministic behavior required for synchronized sensor data alignment. The remote wake-up capability supports low-power parking-mode sensing for features like blind-spot surveillance.
Recommandé
Body Domain Module
Centralized body-domain controllers combine comfort, lighting and access functions into a single ECU that communicates with door modules, headlamp units and climate-control ECUs over a FlexRay backbone. The TLE9222LCXUMA1 provides the physical-layer interface in this topology, with its small PG-TSON-14-3 footprint enabling integration into thin-wall body controllers where z-axis height is limited. The integrated bus failure diagnostics allow the gateway to detect and isolate faulty subnets, while low standby current supports sleep modes that preserve battery life over long parking periods. The 10 Mbit/s bandwidth comfortably carries aggregated body-bus traffic including mirror, seat and lighting commands. Compared with LIN sub-bus transceivers used inside individual doors, the TLE9222LCXUMA1 provides the higher backbone bandwidth required for centralized body-domain architectures.
Recommandé
Hybrid Drive Inverter ECU
Hybrid and electric-drive inverters require robust communication between the inverter ECU, battery management system and vehicle control unit. The TLE9222LCXUMA1 provides the FlexRay physical layer connecting the inverter to the drivetrain backbone, with deterministic time-triggered behavior critical for synchronized torque-vectoring and regenerative-braking coordination. The exposed thermal pad supports heat removal in the high-current PCB environment typical of inverter enclosures, and integrated bus diagnostics enable fault isolation in the presence of high dv/dt switching transients. The compact PG-TSON-14-3 footprint places the transceiver near the MCU without occupying significant PCB area. Compared with CAN-FD used in early hybrid vehicles, FlexRay provides the deterministic latency required for torque-coordination across drive units.
Recommandé
Network Backbone Gateway
Central gateways route traffic between the high-speed FlexRay backbone and lower-speed sub-buses (CAN-FD, LIN) in modern vehicles. The TLE9222LCXUMA1 enables the FlexRay segment of such gateways in a small footprint, supporting multiple FlexRay channels through parallel transceiver instances. Bus failure detection helps the gateway isolate faulty segments, while low standby current supports parasitic drain budgets. The PG-TSON-14-3 package allows multiple transceivers to be placed in close proximity on the gateway PCB, minimizing bus-stub length and improving signal integrity. Compared with earlier FlexRay transceiver generations, the TLE9222LCXUMA1 enables significantly smaller gateway modules - critical for over-the-air (OTA) capable central computing platforms.

Notes de conception
The PG-TSON-14-3 package has an exposed thermal pad (EP) on pin 14 that must be soldered to the PCB ground plane for proper heat removal and electrical performance. Use a footprint with at least 4 thermal vias in the EP land, distributed on a 1.0 mm to 1.2 mm grid. The differential FlexRay bus traces (BP, BM) should be routed as a 100 ohm differential pair with matched lengths and kept clear of noisy switching traces.
Place the TLE9222LCXUMA1 as close as possible to the FlexRay bus connector to minimize stub length. Use Infineon's recommended EMC bus termination network (typically split termination between BP/BM with common-mode capacitors to ground). Route the digital side (TXD, RXD, EN, STBY) away from the bus side and use a ground guard trace between the two regions.
Provide clean VBAT and VCC supplies to the TLE9222LCXUMA1, with local decoupling capacitors (100 nF ceramic + 10 uF bulk) within 2 mm of the supply pins. In noisy automotive environments, additional series ferrite beads on VBAT can improve EMI immunity. The VIO supply (if used) must match the host microcontroller's logic level (3.3 V or 5 V).
Do not use the TLE9222LCXUMA1 on a CAN or LIN bus - the protocol mismatch will prevent communication and may cause bus contention. Ensure the STBY and EN logic levels match the host microcontroller's output voltage; floating these pins can cause indeterminate behavior. Avoid routing the bus traces over PCB splits to maintain the differential impedance.
Informations de conformité
RoHS compliant per distributor product listings (Mouser, DigiKey). AEC-Q100 qualification grade, REACH status, halogen-free status and conflict-minerals compliance should be verified against the latest Infineon product declaration before automotive deployment.
