Product details
Overview
TLE9350VSJXTMA1 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), overtemperature protection, and power-save mode. Used in automotive HS CAN networks interfacing microcontrollers to physical bus layers.
For engineers reviewing the TLE9350VSJXTMA1 datasheet, TLE9350VSJXTMA1 pinout, TLE9350VSJXTMA1 application, or TLE9350VSJXTMA1 equivalent, key selection criteria include CAN FD timing symmetry, ESD robustness (±10 kV HBM on CANH/CANL), low EME without common-mode choke, and AEC-Q100 qualification for engine control units and chassis modules.
Technical Context
The TLE9350VSJXTMA1 implements a fully differential transmitter with matched CANH/CANL output delay symmetry (<1 ns typical) and receiver delay symmetry enabling reliable 5 MBit/s CAN FD operation. Its internal VIO-regulated logic interface decouples microcontroller I/O voltage (3.0–5.5 V) from 5 V VCC supply.
Fail-safe functions include TxD time-out (prevents bus lock-up), thermal shutdown at 170–190 °C with 5–20 K hysteresis, and short-circuit protected outputs. Bus leakage current in power-down state is <1 µA, meeting stringent automotive low-power requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CAN FD Data Rate | Up to 5 MBit/s - Enables high-bandwidth vehicle diagnostics and ADAS sensor fusion via CAN FD frames. |
| VIO Supply Range | 3.0–5.5 V - Allows direct interface to 3.3 V or 5 V microcontrollers without level-shifting circuitry. |
| ESD Robustness (CANH/CANL) | ±10 kV HBM - Eliminates need for external TVS diodes in most automotive harness environments. |
| Bus Leakage (Power-down) | <1 µA - Preserves battery life in always-on vehicle domains (e.g., body control modules). |
| Thermal Shutdown Threshold | 170–190 °C - Protects against irreversible damage during sustained overcurrent or ambient overheating. |
| EME Performance | No external common-mode choke required - Reduces BOM cost and PCB area in ECU designs. |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C ambient) - Qualified for engine bay and transmission control unit deployment. |
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-level input with internal pull-up to VIO; dominant state asserted by logic low. |
| 2 GND | Ground reference | Common return path for VCC, VIO, and bus biasing; must be low-inductance connection. |
| 3 VCC | Transmitter supply | 5 V ±5 % supply; supports power-save mode where VCC can be gated off independently. |
| 4 RxD | Receive data output | CMOS-level output referenced to VIO; dominant state = logic low, recessive = high-impedance. |
| 5 VIO | Digital I/O supply | Configures logic voltage threshold and output swing to match MCU I/O domain (3.3 V or 5 V). |
| 6 CANL | CAN bus low terminal | Differential bus line; requires 120 Ω termination at network ends; withstands −40 V to +40 V DC. |
| 7 CANH | CAN bus high terminal | Differential bus line; paired with CANL; same voltage rating and ESD robustness as CANL. |
| 8 NEN | Not-enable input | Active-low enable; internal VIO pull-up; drives device into standby when high (open or pulled high). |
Key Features
| Feature | Design Value |
|---|---|
| Loop delay symmetry | <1 ns matching between CANH/CANL edges - Ensures minimal bit error rate at 5 MBit/s CAN FD. |
| VIO-adapted I/O interface | Independent 3.0–5.5 V digital supply - Enables seamless integration with legacy 5 V and modern 3.3 V MCUs. |
| TxD time-out function | Auto-reverts to recessive after ~1 ms of continuous dominant TxD - Prevents bus lock-up during MCU hang. |
| Power-save mode | VCC gating capability with <1 µA quiescent current - Supports ultra-low-power wake-on-CAN in body electronics. |
| Overtemperature protection | Hysteresis-controlled shutdown (170–190 °C trip, 150 °C recovery) - Guarantees safe thermal margin under fault conditions. |

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 | Supports up to 2 MBit/s (not 5 MBit/s); lower ESD (±8 kV HBM); no VIO pin - fixed 5 V logic interface. | Limited to legacy CAN FD or classical CAN networks; unsuitable for high-throughput ADAS sensor fusion. | Select when cost sensitivity outweighs speed requirement and MCU is 5 V only. |
| ST TLE6250G | Classical CAN only (1 MBit/s max); no CAN FD support; higher bus leakage (>5 µA in sleep); no VIO adaptation. | Applicable only in non-FD automotive networks; lacks VeLIO certification and 5 MBit/s timing symmetry. | Choose only for brownfield upgrades where CAN FD is not required and footprint compatibility is critical. |
Compared with TJA1044T/3 and TLE6250G, the TLE9350VSJXTMA1 uniquely delivers 5 MBit/s CAN FD performance with VIO flexibility, VeLIO certification, and sub-1 µA power-down leakage-making it the sole option for next-generation high-bandwidth automotive domain controllers requiring AEC-Q100 Grade 1 compliance.

FAQ
What is the maximum CAN FD data rate supported by TLE9350VSJXTMA1?
The TLE9350VSJXTMA1 supports CAN FD data rates up to 5 MBit/s, enabled by its precisely matched transmitter and receiver loop delay symmetry (<1 ns). This performance is validated per ISO 11898-2:2016 and confirmed in real-world network implementations with ≤30 m bus length and ≤50 pF/m parasitic capacitance.
Does TLE9350VSJXTMA1 require an external common-mode choke?
No. The TLE9350VSJXTMA1 achieves very low electromagnetic emission (EME) through optimized transmitter symmetry and does not require an external common-mode choke to meet CISPR 25 Class 5 limits. This is verified in Infineon's VeLIO test reports and documented in the application example section of the datasheet.
How does the VIO pin function in TLE9350VSJXTMA1?
The VIO pin supplies the digital I/O interface and sets the logic threshold and output voltage levels for TxD, RxD, NEN, and VIO-referenced internal circuits. It accepts 3.0–5.5 V, allowing direct connection to either 3.3 V or 5 V microcontrollers without external level shifters-verified in Section 7.2.2 of the datasheet.
Is TLE9350VSJXTMA1 qualified for automotive use?
Yes. The TLE9350VSJXTMA1 is qualified according to AEC-Q100 Grade 1 (−40 °C to +125 °C ambient), with full validation for engine control, transmission, and chassis applications. It meets ISO 7637-2/3 and SAE J2962-2 transient immunity requirements and carries VeLIO interoperability certification.
