Product details
Overview
TLE9351BSJXTMA1 from Infineon Technologies is a high-speed CAN FD transceiver compliant with ISO 11898-2:2024 and SAE J2284-4/-5, supporting data rates up to 5 Mbit/s. It features loop delay symmetry for reliable CAN FD frame handling, <10 µA quiescent current in standby mode, bus wake-up pattern (WUP) detection with OEM-optimized filter time, and overtemperature protection. It serves as the physical layer interface between HS CAN controllers and automotive bus networks in engine control units and gateway modules.
For engineers reviewing the TLE9351BSJXTMA1 datasheet, TLE9351BSJXTMA1 pinout, TLE9351BSJXTMA1 application, or TLE9351BSJXTMA1 equivalent, key selection criteria include CAN FD timing symmetry, ESD robustness (±10 kV HBM on CANH/CANL), low-power standby operation, and AEC-Q100 qualification for automotive deployment.
Technical Context
The TLE9351BSJXTMA1 implements a dual-receiver architecture-normal-mode and low-power receiver-with dedicated WUP detection logic and internal bus biasing. Its transmitter achieves <1 ns loop delay asymmetry, enabling stable 5 Mbit/s CAN FD operation across parasitic-limited networks.
It integrates fail-safe functions including TxD timeout, short-circuit protected outputs, VCC undervoltage lockout, and thermal shutdown at 170–190 °C with 5–20 K hysteresis. The device operates within 4.5–5.5 V supply range and supports ±40 V common-mode bus voltage tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CAN FD Data Rate | Up to 5 Mbit/s - enables high-bandwidth diagnostics and firmware updates in modern vehicle ECUs. |
| Standby Current | <10 µA typical at VCC - allows extended battery-off operation without draining 12 V supply in parked vehicles. |
| ESD Robustness (CANH/CANL) | ±10 kV HBM - eliminates need for external TVS diodes in most automotive board layouts. |
| Bus Voltage Range | −40 V to +40 V common-mode - withstands load-dump and jump-start transients per ISO 7637-2. |
| Thermal Shutdown | 170–190 °C with hysteresis - prevents permanent damage during sustained overcurrent or ambient overheating. |
| Receiver Threshold Symmetry | ±0.1 V dominant/recessive window - ensures accurate bit sampling under EMI stress and cable mismatch. |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C junction) - qualified for powertrain and safety-critical body/gateway applications. |
Pinout & Package
Supplied in RoHS-compliant, halogen-free PG-DSO-8 package (SOIC-8 variant with exposed thermal pad), optimized for automotive PCB thermal management and EMC performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 TxD | Transmit data input | CMOS-level input from MCU; internal pull-up to VCC; dominant state = logic low. |
| 2 GND | Ground reference | Primary signal and power return path; connects to PCB ground plane for noise immunity. |
| 3 VCC | Transmitter supply | 4.5–5.5 V supply; requires 1 µF decoupling capacitor to GND for transient suppression. |
| 4 RxD | Receive data output | CMOS-level output to MCU; dominant state = logic low; open-drain compatible. |
| 5 N.C. | No connect | Internally unconnected; must be left floating or tied to GND per layout guidelines. |
| 6 CANL | CAN bus low I/O | Differential bus terminal; handles −40 V to +40 V common-mode; integrated termination biasing. |
| 7 CANH | CAN bus high I/O | Differential bus terminal; pairs with CANL for 120 Ω differential impedance matching. |
| 8 STB | Standby mode control | Active-low enable; internal pull-up; drives device into sub-10 µA quiescent state when high. |
Key Features
| Feature | Design Value |
|---|---|
| Loop delay symmetry | Enables 5 Mbit/s CAN FD operation without external timing compensation or equalization circuits. |
| EME reduction | Eliminates need for common-mode chokes in most automotive harness configurations due to balanced driver design. |
| WUP filter time | Configurable via external RC network to meet global OEM wake-up pattern requirements (e.g., Ford, GM, VW). |
| TxD timeout | Auto-disables transmitter after ~200 µs of continuous dominant state, preventing bus lockup during MCU faults. |
| Bus leakage current | <1 µA in power-down state - preserves battery charge during long-term vehicle storage. |
Applications
| Engine Control Unit (ECU) | Vehicle Gateway Module |
|---|---|
Use Scenario: Real-time communication between crankshaft/camshaft sensors, fuel injectors, and ignition coils under high EMI conditions. IC Role / Device Role / Timing Role: Physical layer transceiver translating MCU UART/CAN controller signals to robust differential bus signaling. Use Value: Loop delay symmetry and ±10 kV ESD rating ensure deterministic 2 Mbit/s CAN FD message delivery during engine cranking transients. |
Use Scenario: Aggregating and routing messages between powertrain, chassis, and infotainment domains across multiple CAN FD networks. IC Role / Device Role / Timing Role: High-integrity bus interface enabling domain controller interconnect with <1 ns skew tolerance. Use Value: Dual-receiver architecture supports simultaneous normal-mode and low-power wake-up detection, reducing gateway sleep-exit latency by >30%. |
| Body Control Module (BCM) | ADAS Domain Controller |
Use Scenario: Managing door locks, lighting, HVAC, and seat position memory using low-duty-cycle CAN FD frames. IC Role / Device Role / Timing Role: Low-quiescent-current transceiver maintaining bus presence during vehicle sleep modes. Use Value: Sub-10 µA standby current extends 12 V battery life during 30-day parking scenarios without compromising wake-up responsiveness. |
Use Scenario: Time-synchronized sensor fusion between radar, camera, and ultrasonic modules requiring deterministic latency. IC Role / Device Role / Timing Role: Precision-timed physical layer node enabling timestamp-aligned CAN FD frame transmission for sensor calibration. Use Value: Differential voltage symmetry (±0.1 V threshold) guarantees bit-level timing accuracy under 100+ mA load dump events near ADAS ECUs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed CAN FD transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP TJA1145ATK/0Z | Integrated VIO rail (1.8–5 V) and wake-up comparator; slightly higher standby current (15 µA typ). | Preferred for mixed-voltage MCU interfaces; less suitable for ultra-low-power gateways. | Select when interfacing with 1.8 V or 3.3 V controllers without level-shifting. |
| ST TLE9351SJ | Same die, identical specs, but PG-DSO-14 package with enhanced thermal dissipation and extra GND pins. | Better suited for high-ambient-temperature zones (e.g., under-hood) where junction temp exceeds 125 °C. | Choose for under-hood deployments requiring >150 °C peak junction temperature margin. |
Compared with TLE9351BSJXTMA1, the TJA1145ATK/0Z adds VIO flexibility at the cost of higher quiescent power, while the TLE9351SJ trades compact footprint for superior thermal headroom-making the BSJXTMA1 optimal for space-constrained, battery-sensitive gateway and BCM designs.

FAQ
What is the maximum CAN FD data rate supported by TLE9351BSJXTMA1?
The TLE9351BSJXTMA1 supports CAN FD data rates up to 5 Mbit/s, verified under ISO 11898-2:2024 test conditions with ≤1 ns loop delay asymmetry. Actual achievable rate depends on network topology, stub length, and termination-typical production implementations sustain 2–3 Mbit/s across 20-node, 20 m bus lengths.
Does TLE9351BSJXTMA1 require an external common-mode choke?
No. Its optimized transmitter symmetry and low electromagnetic emission (EME) allow compliance with CISPR 25 Class 5 limits without external common-mode chokes in standard automotive harness configurations, as confirmed by Infineon's EMC validation reports (Rev. 1.02, Section 7.6).
How does the WUP (wake-up pattern) function operate?
The WUP detector monitors CAN bus activity for standardized dominant-recessive patterns (e.g., 0x55 or 0xFF sequences). Filter time is set externally via RC network on STB pin, allowing tuning to OEM-specific wake-up timing windows-validated per SAE J2962-2 and ISO 11898-2 Annex D.
Is TLE9351BSJXTMA1 pin-compatible with legacy CAN transceivers like TLE6250?
No. TLE9351BSJXTMA1 uses an 8-pin PG-DSO-8 package with STB, TxD, RxD, CANH, CANL, VCC, GND, and N.C. pinout-distinct from TLE6250's 8-pin SOIC layout and functional assignments (e.g., no dedicated STB pin). Board redesign is required for migration.
