Product details
Overview
TLE9351BVSJXTMA1 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 with loop delay symmetry optimized for CAN FD frames. It features VIO voltage adaptation (3.3 V or 5 V), standby mode with <10 µA quiescent current on VIO, and integrated bus wake-up pattern detection. Used in automotive gateway and body control modules for robust HS CAN communication.
For engineers reviewing the TLE9351BVSJXTMA1 datasheet, TLE9351BVSJXTMA1 pinout, TLE9351BVSJXTMA1 application, or TLE9351BVSJXTMA1 equivalent, key selection criteria include CAN FD timing symmetry, VeLIO certification, EME performance without common-mode choke, and AEC-Q100 qualification for automotive deployment.
Technical Context
The TLE9351BVSJXTMA1 implements a dual-receiver architecture-normal-mode and low-power receiver-with dedicated wake-up pattern (WUP) filtering logic and STB-controlled mode transition. Its transmitter uses symmetric drive circuitry to minimize differential skew, enabling reliable 5 Mbit/s CAN FD operation across parasitic-limited networks.
It integrates fail-safe functions including TxD timeout, overtemperature shutdown (170–190 °C), short-circuit protection, and ISO 7637/SAE J2962-2 transient immunity. The VIO-supplied digital interface decouples logic-level adaptation from VCC, allowing independent power domain management during standby.
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. |
| Standby Quiescent Current (VIO) | <10 µA - allows persistent bus monitoring with negligible battery drain in always-on vehicle domains. |
| VIO Supply Range | 3.0 V to 5.5 V - supports direct interfacing with 3.3 V or 5 V microcontrollers without level shifters. |
| ESD Robustness (CANH/CANL) | ±10 kV HBM - eliminates need for external TVS diodes in most automotive harness environments. |
| EME Performance | No external common-mode choke required - meets stringent OEM EMC limits across 150 kHz–1 GHz range. |
| Thermal Shutdown Threshold | 170–190 °C - protects against latch-up and permanent damage during sustained overcurrent or ambient overheating. |
| AEC-Q100 Qualification | Qualified per Grade 1 (−40 °C to +125 °C ambient) - validated for under-hood and cabin ECU placement. |
Pinout & Package
Package: PG-DSO-8 (RoHS-compliant, halogen-free, surface-mount SOIC variant with exposed thermal pad).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 TxD | Transmit data input | CMOS-compatible input with internal VIO pull-up; dominant state asserted by logic low. |
| 2 GND | Ground reference | Common return path for VCC, VIO, and CAN bus biasing; requires low-inductance PCB connection. |
| 3 VCC | Transmitter supply | 4.5–5.5 V supply for CANH/CANL drivers; can be disabled in standby to reduce system quiescent load. |
| 4 RxD | Receive data output | CMOS output referenced to VIO; dominant state = logic low; open-drain compatible via external pull-up. |
| 5 VIO | Digital I/O supply | Sets logic thresholds for TxD/RxD/STB; powers low-power receiver and wake-up filter during VCC-off standby. |
| 6 CANL | CAN bus low terminal | Half of differential bus interface; internally biased to VCC/2; withstands ±40 V DC transients. |
| 7 CANH | CAN bus high terminal | Differential bus partner to CANL; symmetric rise/fall times ensure minimal EME and jitter. |
| 8 STB | Standby mode control | Active-low input with internal VIO pull-up; drives device into low-power mode when pulled low. |
Key Features
| Feature | Design Value |
|---|---|
| Loop delay symmetry | Optimized for ≤10 ns mismatch between CANH/CANL edges - ensures clean bit sampling at 5 Mbit/s. |
| VeLIO certification | Fully tested per Vehicle LAN Interoperability and Optimization requirements - guarantees plug-and-play compatibility across OEM networks. |
| Bus wake-up pattern (WUP) | Configurable filter time per global OEM specifications - enables selective wake-up without false triggers from noise or glitches. |
| TxD timeout protection | Auto-disables driver after ~20 µs of continuous dominant state - prevents bus lockup due to MCU hang or software fault. |
| Overtemperature protection | Hysteresis of 5–20 K between shutdown and recovery - avoids thermal oscillation during transient overload 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 TJA1145A | Supports partial networking (PN) and has integrated VIO regulator; slightly higher standby current (15 µA vs. <10 µA). | Preferred where PN-based wake-up coordination across multiple ECUs is required. | Select if system-level partial networking support is mandatory and VIO regulation simplifies power design. |
| ST TLE6250G | Legacy CAN 2.0B only (1 Mbit/s max); no CAN FD support; lower ESD rating (±8 kV); lacks VeLIO certification. | Suitable only for cost-sensitive legacy BCMs without bandwidth or interoperability requirements. | Choose only for brownfield designs where CAN FD and VeLIO compliance are not needed. |
Compared with TLE9351BVSJXTMA1, the TJA1145A adds partial networking but trades off standby efficiency, while the TLE6250G omits CAN FD entirely-making the TLE9351BVSJXTMA1 the optimal choice for new AEC-Q100-compliant CAN FD deployments demanding low EME and OEM interoperability.

FAQ
What is the maximum CAN FD data rate supported by the TLE9351BVSJXTMA1?
The TLE9351BVSJXTMA1 supports CAN FD data rates up to 5 Mbit/s, enabled by its precisely matched transmitter loop delay symmetry and receiver delay symmetry. This performance is verified under ISO 11898-2:2024 test conditions and confirmed across network lengths up to 40 m with standard 120 Ω termination.
Does the TLE9351BVSJXTMA1 require an external common-mode choke for EMC compliance?
No. The TLE9351BVSJXTMA1 achieves certified electromagnetic emission (EME) performance across 150 kHz–1 GHz without an external common-mode choke, thanks to its highly symmetric CANH/CANL output drivers and optimized RF immunity. This is validated per VeLIO test requirements and OEM-specific EMC protocols.
How does the standby mode reduce power consumption?
In standby mode, the TLE9351BVSJXTMA1 disables VCC supply to the transmitter while retaining VIO-powered low-power receiver and wake-up logic. This reduces total quiescent current to less than 10 µA on VIO, enabling continuous bus monitoring without draining the vehicle battery during extended parking periods.
Is the TLE9351BVSJXTMA1 qualified for under-hood automotive applications?
Yes. The device is AEC-Q100 qualified for Grade 1 (−40 °C to +125 °C ambient), with junction temperature operation up to 150 °C and thermal shutdown activation at 170–190 °C. Its PG-DSO-8 package and ISO 7637/SAE J2962-2 transient protection make it suitable for engine bay and powertrain ECU placements.
