Product details
Overview
TLE9350XSJXTMA1 from Infineon is a high-speed CAN FD transceiver compliant with ISO 11898-2:2016 and SAE J2284-4/-5, supporting data rates up to 5 MBit/s with loop delay symmetry optimized for CAN FD frames. It features VIO voltage adaptation (3.3 V or 5 V), receive-only mode, and overtemperature protection. Used as the physical layer interface between microcontroller CAN controllers and automotive HS CAN buses in engine control units and body control modules.
For engineers reviewing the TLE9350XSJXTMA1 datasheet, TLE9350XSJXTMA1 pinout, TLE9350XSJXTMA1 application, or TLE9350XSJXTMA1 equivalent, key selection criteria include CAN FD timing symmetry, ESD robustness (±10 kV HBM on CANH/CANL), low EME enabling choke-free layout, fail-safe TxD time-out, and AEC-Q100 qualification for automotive deployment.
Technical Context
The TLE9350XSJXTMA1 implements a fully differential transmitter with matched CANH/CANL output delay and rise/fall time symmetry, enabling reliable 5 MBit/s CAN FD operation across automotive network topologies. Its receiver includes a normal-mode comparator with internal bus biasing and a dedicated receive-only input (RM) that disables driver output while preserving bus monitoring capability.
Fail-safe operation is enforced via integrated thermal shutdown (170–190 °C trip), VCC undervoltage detection, short-circuit protected outputs, and TxD time-out that forces recessive state after 1.2 ms of continuous dominant assertion. The VIO pin decouples logic-level translation from VCC, allowing independent 3.3 V or 5 V MCU interface compatibility without level-shifter components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CAN FD Data Rate | Up to 5 MBit/s - Enables high-bandwidth firmware updates and sensor fusion in modern ECUs without protocol layer changes. |
| ESD Robustness (CANH/CANL) | ±10 kV HBM - Eliminates need for external TVS diodes in most automotive harness environments. |
| VIO Supply Range | 3.0 V to 5.5 V - Allows direct interfacing with both 3.3 V and 5 V microcontrollers without external level shifters. |
| Thermal Shutdown Threshold | 170–190 °C - Protects against latch-up during sustained bus fault conditions while maintaining operational margin. |
| Bus Leakage Current (Power-down) | < 1 µA - Minimizes quiescent current in sleep-mode vehicle networks to meet ULP requirements. |
| EME Performance | No external common mode choke required - Meets CISPR 25 Class 5 limits due to intrinsic signal symmetry and RF immunity. |
| AEC-Q100 Grade | Grade 0 (−40 °C to +150 °C TJ) - Qualified for under-hood applications including engine control and transmission systems. |
Pinout & Package
Package: PG-DSO-8 (RoHS-compliant, halogen-free, 8-pin exposed pad SOIC variant with thermal enhancement).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 TxD | Transmit data input | CMOS input with internal pull-up to VIO; dominant state asserted by logic low; enables MCU-driven bus arbitration. |
| 2 GND | Ground reference | Common return path for VCC, VIO, and CAN bus termination; requires low-inductance PCB connection to minimize EMI. |
| 3 VCC | Transmitter supply | 5 V ±5% supply for CANH/CANL drivers; requires 1 µF ceramic decoupling capacitor near pin. |
| 4 RxD | Receive data output | CMOS output referenced to VIO; dominant state = logic low; drives MCU RX pin directly. |
| 5 VIO | Digital I/O supply | Configures logic thresholds and output swing for TxD/RxD/RM pins; supports 3.3 V or 5 V MCU interfaces. |
| 6 CANL | CAN bus low terminal | Differential bus node; must be terminated with 120 Ω resistor at network ends; connects to twisted-pair CAN-L wire. |
| 7 CANH | CAN bus high terminal | Differential bus node; paired with CANL; connects to twisted-pair CAN-H wire; symmetric drive ensures low EME. |
| 8 RM | Receive-only mode enable | Logic low disables transmitter output while preserving receiver functionality - used for diagnostic bus monitoring without interference. |
Key Features
| Feature | Design Value |
|---|---|
| Loop delay symmetry | Optimized to < 10 ns mismatch between CANH/CANL edges - ensures clean bit sampling at 5 MBit/s even on long stubs. |
| VIO-adapted I/O | Independent 3.0–5.5 V digital supply allows seamless integration with legacy 5 V and modern 3.3 V MCUs without external level shifters. |
| TxD time-out function | Auto-reverts to recessive after 1.2 ms dominant assertion - prevents bus lockup during MCU hang or software fault. |
| Power-down leakage | < 1 µA total bus leakage - meets ISO 11898-2 standby current requirements for always-on vehicle networks. |
| Overtemperature protection | Hysteresis of 5–20 K with 170–190 °C trip point - provides robust thermal margin during load dump or short-circuit events. |

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 TJA1044T/3 | Lower ESD rating (±8 kV HBM on CANH/CANL); no VIO pin - fixed 5 V logic interface only. | Limited to 5 V MCU designs; less robust in high-EMI motor environments. | Select when cost sensitivity outweighs need for 3.3 V compatibility or highest ESD margin. |
| ST TSN72101TR | Supports 2 MBit/s max; lacks TxD time-out and receive-only mode; lower thermal shutdown threshold (150 °C). | Suitable for non-safety-critical body networks but not EPS or powertrain applications. | Choose for cost-optimized BCM/LIN gateway use where full CAN FD bandwidth is unnecessary. |
Compared with TJA1044T/3 and TSN72101TR, the TLE9350XSJXTMA1 uniquely combines 5 MBit/s CAN FD support, VIO flexibility, ±10 kV ESD, and fail-safe TxD time-out - making it the only option qualified for AEC-Q100 Grade 0 powertrain applications requiring deterministic high-speed communication and robust fault handling.

FAQ
What is the maximum CAN FD data rate supported by the TLE9350XSJXTMA1?
The TLE9350XSJXTMA1 supports CAN FD data rates up to 5 MBit/s, verified through loop delay symmetry measurements and compliance testing per ISO 11898-2:2016 Annex D. This performance is achievable across typical automotive network topologies with up to 30 m bus length and ≤5 nodes, assuming proper termination and PCB layout.
Does the TLE9350XSJXTMA1 require an external common mode choke?
No. The TLE9350XSJXTMA1 achieves CISPR 25 Class 5 EME compliance without an external common mode choke due to its intrinsically balanced transmitter output stage and optimized receiver delay symmetry, as validated in Infineon's VeLIO test reports and application note AN230121.
How does the VIO pin affect logic-level compatibility?
The VIO pin sets the reference voltage for all digital I/O pins (TxD, RxD, RM), allowing direct interface with either 3.3 V or 5 V microcontrollers. When VIO = 3.3 V, TxD recognizes logic low below 0.8 V and RxD outputs 0–3.3 V swings; at VIO = 5 V, thresholds scale accordingly - eliminating external level-shifting circuitry.
What happens during thermal shutdown?
When junction temperature exceeds 170–190 °C, the TLE9350XSJXTMA1 disables transmitter output and enters thermal shutdown with hysteresis of 5–20 K. Receiver remains active to allow bus monitoring, and full functionality resumes only after temperature falls below the hysteresis threshold - preventing oscillation during recovery.
