Product details
Overview
TLE9351VSJXTMA1 from Infineon is a high-speed CAN FD transceiver compliant with ISO 11898-2:2016 and SAE J2284-4/-5, serving as the physical layer interface between HS CAN protocol controllers and automotive bus networks. It supports data rates up to 5 MBit/s, features VIO voltage adaptation (3.3 V or 5 V), and delivers <10 µA quiescent current in stand-by mode - enabling low-power gateway and body control modules.
For engineers reviewing the TLE9351VSJXTMA1 datasheet, TLE9351VSJXTMA1 pinout, TLE9351VSJXTMA1 application, or TLE9351VSJXTMA1 equivalent, key selection criteria include CAN FD timing symmetry, VeLIO certification, EME performance without common-mode chokes, and AEC-Q100 qualification for automotive deployment.
Technical Context
The TLE9351VSJXTMA1 implements dual-receiver architecture (normal-mode + low-power receiver) with wake-up pattern (WUP) detection optimized for global OEM requirements. Its transmitter employs loop delay symmetry and matched CANH/CANL edge timing to ensure robust CAN FD frame integrity at 5 MBit/s under parasitic network conditions.
Fail-safe operation includes TxD time-out, overtemperature shutdown (170–190 °C trip), short-circuit protection, and VCC undervoltage lockout. Bus-side ESD immunity reaches ±10 kV HBM on CANH/CANL, while digital pins tolerate ±2 kV HBM - eliminating need for external suppressor diodes in most automotive layouts.
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 networks. |
| VIO Supply Range | 3.0 V to 5.5 V - allows direct interfacing with 3.3 V or 5 V microcontrollers without level shifters. |
| Stand-by Quiescent Current | <10 µA on VIO - extends battery life in always-on vehicle modules during sleep states. |
| Bus ESD Immunity | ±10 kV HBM on CANH/CANL - meets stringent automotive EMC requirements without external TVS diodes. |
| Thermal Shutdown | 170–190 °C trip range with 5–20 K hysteresis - prevents latch-up and ensures safe recovery after thermal overload. |
| EME Performance | No external common-mode choke required - validated per VeLIO test suite for low radiated emissions. |
| AEC-Q100 Grade | Qualified per Grade 1 (−40 °C to +125 °C ambient) - suitable for under-hood and cabin ECUs. |
Pinout & Package
Package: PG-DSO-8 (RoHS-compliant, halogen-free, 8-pin exposed pad SOIC variant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 TxD | Transmit data input | CMOS-level input with internal pull-up to VIO; dominant state = logic low. |
| 2 GND | Ground reference | Common return path for VCC, VIO, and bus biasing; connects to exposed thermal pad. |
| 3 VCC | Transmitter supply | 4.75–5.25 V supply; can be disabled in stand-by to minimize system power draw. |
| 4 RxD | Receive data output | CMOS-level output referenced to VIO; dominant state = logic low. |
| 5 VIO | Digital supply input | Sets logic voltage levels for TxD/RxD/STB; powers low-power receiver during stand-by. |
| 6 CANL | CAN bus low I/O | Differential bus terminal; biased internally to VCC/2 for common-mode stability. |
| 7 CANH | CAN bus high I/O | Differential bus terminal; paired with CANL for full-duplex HS CAN signaling. |
| 8 STB | Stand-by control input | Active-low enable; internal pull-up to VIO; asserts stand-by when pulled low. |
Key Features
| Feature | Design Value |
|---|---|
| Loop delay symmetry | Enables reliable 5 MBit/s CAN FD data frames by minimizing skew between transmit and receive paths. |
| VeLIO certification | Validated interoperability across OEM vehicle LANs - reduces integration validation effort in multi-supplier architectures. |
| VIO voltage adaptation | Eliminates external level-shifting circuitry when interfacing with mixed-voltage microcontrollers (3.3 V or 5 V). |
| Bus wake-up pattern filter | Configurable WUP detection window compliant with global OEM specifications - avoids false wake-ups in noisy environments. |
| Power-down bus leakage | <1 µA CANH/CANL leakage in power-down - preserves bus integrity and prevents unintended node activation. |
Applications
| Gateway Modules | Body Control Modules (BCM) |

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 TJA1044GT/3 | Lower max data rate (2 MBit/s), no VIO pin - fixed 5 V logic interface only. | Limited to classical CAN and low-speed FD; unsuitable for 5 MBit/s diagnostic channels. | Select when cost sensitivity outweighs FD bandwidth needs and 3.3 V MCU interfacing is not required. |
| ST TLE6250G | Classical CAN-only (1 MBit/s), no CAN FD support, higher quiescent current (15 µA stand-by). | Not qualified for CAN FD networks; lacks VeLIO certification and 5 MBit/s timing symmetry. | Choose only for legacy CAN 2.0 designs where FD upgrade path is not planned. |
Compared with TJA1044GT/3 and TLE6250G, the TLE9351VSJXTMA1 uniquely combines 5 MBit/s FD capability, dual-voltage VIO adaptability, VeLIO compliance, and <10 µA stand-by current - making it the only option for next-gen automotive gateways requiring both bandwidth and ultra-low-power operation.

FAQ
Is the TLE9351VSJXTMA1 compatible with both 3.3 V and 5 V microcontrollers?
Yes - the VIO pin accepts 3.0 V to 5.5 V, allowing direct connection to either 3.3 V or 5 V MCUs without external level shifters. The TxD input and RxD output logic thresholds scale with VIO, ensuring noise-immune signaling across both voltage domains.
Does the device require an external common-mode choke for EMC compliance?
No - the TLE9351VSJXTMA1 achieves VeLIO-certified EME performance through intrinsic CANH/CANL output symmetry and optimized driver timing, eliminating the need for external common-mode chokes in most automotive PCB layouts per ISO 11898-2:2016 test limits.
What is the wake-up behavior in stand-by mode?
In stand-by mode, the low-power receiver remains active with <10 µA VIO current. A valid bus wake-up pattern (WUP) triggers transition to normal mode within <100 µs. The WUP filter time is factory-configured to meet global OEM specifications, preventing spurious wake-ups from bus noise.
How does the TxD time-out function protect the system?
The TxD time-out disables the transmitter output if TxD remains dominant (>50% duty cycle) for longer than 200 µs, preventing bus lock-up due to MCU software hangs or faulty TX drivers. Recovery occurs automatically upon TxD release, restoring bus arbitration without reset.
