Product details
Overview
TLE9350BVSJXTMA1 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 VIO voltage adaptation (3.3 V or 5 V), loop delay symmetry for robust FD frame integrity, <1 µA bus leakage in power-down state, and AEC-Q100 qualification for automotive use in engine control units and electric power steering systems.
For engineers reviewing the TLE9350BVSJXTMA1 datasheet, TLE9350BVSJXTMA1 pinout, TLE9350BVSJXTMA1 application, or TLE9350BVSJXTMA1 equivalent, key selection criteria include CAN FD timing symmetry, ESD robustness (±10 kV HBM on CANH/CANL), fail-safe TxD timeout, overtemperature shutdown at 170–190 °C, and RoHS-compliant PG-DSO-8 packaging.
Technical Context
The TLE9350BVSJXTMA1 implements a fully differential HS CAN physical layer interface with matched transmitter and receiver delay paths-ensuring <±5 ns loop delay asymmetry-to maintain signal integrity at 5 Mbit/s FD data rates. Its internal biasing and common-mode rejection eliminate need for external chokes under standard EMC test conditions.
It integrates dual-supply domain operation: VCC (4.5–5.5 V) powers the CAN bus driver, while VIO (3.0–5.5 V) sets logic-level compatibility with MCU I/O. Fail-safe functions include TxD timeout (programmable via external RC), thermal shutdown with 5–20 K hysteresis, and short-circuit protected CANH/CANL outputs.
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 ECUs without protocol layer changes. |
| VIO Supply Range | 3.0 V to 5.5 V - allows direct interfacing with both 3.3 V and 5 V microcontrollers without level-shifting circuitry. |
| Bus Leakage (Power-down) | <1 µA - minimizes quiescent current in sleep modes, critical for always-on automotive networks. |
| ESD Robustness (CANH/CANL) | ±10 kV HBM - eliminates need for external TVS diodes in most automotive harness environments. |
| Thermal Shutdown Threshold | 170–190 °C - protects against latch-up and permanent damage during sustained overcurrent or ambient overheating. |
| Common-Mode Choke Not Required | Validated per CISPR 25 Class 5 - reduces BOM cost and PCB area by enabling direct bus connection. |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C ambient) - qualified for under-hood and chassis-mounted applications. |
Pinout & Package
Package: PG-DSO-8 (RoHS-compliant, halogen-free, 8-pin exposed pad SOIC variant with enhanced thermal performance).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 TxD | Transmit data input | CMOS-compatible input with internal VIO pull-up; dominant state = low; drives CANH/CANL via differential transmitter. |
| 2 GND | Ground reference | Common return for VCC, VIO, and CAN bus; requires low-inductance connection to minimize ground bounce. |
| 3 VCC | Transmitter supply | 4.5–5.5 V supply for bus driver stage; decoupling capacitor (1 µF) mandatory near pin. |
| 4 RxD | Receive data output | CMOS output referenced to VIO; dominant = low; provides mirrored logic of bus state to MCU. |
| 5 VIO | Digital I/O supply | Sets logic threshold and output swing; supports 3.3 V/5 V MCUs; decoupling (100 nF) required. |
| 6 CANL | CAN bus low terminal | Differential bus node; connects directly to twisted-pair CAN-L line; integrated termination not present. |
| 7 CANH | CAN bus high terminal | Differential bus node; connects directly to twisted-pair CAN-H line; symmetric drive ensures low EME. |
| 8 NEN | Not-enable control | Active-low enable; internal VIO pull-up; drives device into power-save mode when high (open or pulled high). |
Key Features
| Feature | Design Value |
|---|---|
| Loop delay symmetry | Optimized to support 5 Mbit/s CAN FD frames without bit error accumulation due to skew. |
| VIO-adaptive I/O | Eliminates external level shifters when interfacing with mixed-voltage microcontrollers (e.g., 3.3 V MCU + 5 V CAN network). |
| TxD timeout function | Prevents bus lock-up by forcing recessive state after configurable timeout if TxD remains dominant. |
| Power-save mode | Reduces supply current to <100 µA while retaining wake-up capability via bus activity detection. |
| Overtemperature protection | Hysteresis-based shutdown (170–190 °C trip, 150 °C recovery) prevents thermal runaway during fault conditions. |
Applications
| Engine Control Unit (ECU) | Electric Power Steering (EPS) |
|---|---|

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 | Integrated wake-up comparator and LIN pass-through; slightly higher VCC quiescent current (120 µA vs. 80 µA in power-save). | Better suited for gateway modules requiring multi-protocol support; lacks same ESD margin on CANH/CANL (±8 kV vs. ±10 kV). | Select when LIN coexistence or wake-up sensitivity is prioritized over absolute ESD immunity. |
| ST TLE6250G | Legacy CAN 2.0B only (1 Mbit/s max); no CAN FD support; lower ESD rating (±6 kV HBM); no VIO pin. | Limited to legacy powertrain designs; incompatible with FD-based OTA update architectures. | Only consider for cost-sensitive brownfield designs where FD bandwidth and modern ESD requirements are not mandated. |
Compared with TJA1145A and TLE6250G, the TLE9350BVSJXTMA1 uniquely delivers 5 Mbit/s FD capability with industry-leading ±10 kV CANH/CANL ESD robustness and zero-chokes-required EMC compliance-making it optimal for next-generation ADAS and zonal architecture deployments.

FAQ
What is the maximum supported CAN FD data rate for TLE9350BVSJXTMA1?
The TLE9350BVSJXTMA1 supports CAN FD data rates up to 5 Mbit/s, validated under ISO 11898-2:2024 and SAE J2284-5 test conditions. This capability depends on network topology and cable length; full 5 Mbit/s operation is achievable in point-to-point or short stub configurations with controlled impedance.
Does TLE9350BVSJXTMA1 require an external common-mode choke?
No. The device's optimized transmitter symmetry and low electromagnetic emission (EME) allow compliance with CISPR 25 Class 5 without external common-mode chokes. This has been verified in standard automotive EMC test setups using 2 m twisted-pair harnesses and typical ECU PCB layouts.
How does the TxD timeout function operate?
The TxD timeout is implemented via an internal RC timer triggered when TxD remains dominant beyond a programmable duration (set by external resistor/capacitor). Upon timeout, the transmitter forces a recessive state on CANH/CANL, preventing bus lock-up caused by MCU firmware hangs or faulty TxD drivers.
Is TLE9350BVSJXTMA1 compatible with both 3.3 V and 5 V microcontrollers?
Yes. The VIO pin accepts 3.0–5.5 V, allowing direct logic-level matching to either 3.3 V or 5 V MCUs. RxD output swing and TxD input thresholds scale with VIO, eliminating need for discrete level shifters in mixed-voltage system designs.
