Product details
Overview
TLE9350SJXTMA1 from Infineon is a high-speed CAN FD transceiver compliant with ISO 11898-2:2016 and SAE J2284-4/-5, designed for HS CAN physical layer interfacing in automotive ECUs. It supports data rates up to 5 MBit/s, features loop delay symmetry <1 ns, delivers <10 µA bus leakage in power-down state, and includes TxD time-out, overtemperature protection, and receive-only mode - deployed in engine control units and electric power steering systems.
For engineers reviewing the TLE9350SJXTMA1 datasheet, TLE9350SJXTMA1 pinout, TLE9350SJXTMA1 application, or TLE9350SJXTMA1 equivalent, key selection criteria include CAN FD timing symmetry, ESD robustness (±10 kV HBM on CANH/CANL), fail-safe modes (power-save, receive-only), and AEC-Q100 qualification for under-hood deployment.
Technical Context
The TLE9350SJXTMA1 implements a fully differential transmitter with matched CANH/CANL rise/fall times (<1 ns asymmetry) and a high-symmetry receiver path enabling reliable 5 MBit/s CAN FD frame handling. Its internal VCC/2 reference stabilizes common-mode voltage during dominant/recessive transitions, reducing electromagnetic emission without external chokes.
Fail-safe operation is enforced via integrated thermal shutdown (170–190 °C trip), TxD time-out (prevents bus lock-up), and undervoltage detection on VCC (4.75–5.25 V functional range). Mode control uses active-low NEN and NRM pins to enter normal, receive-only, or power-save states with defined delay timing per ISO 11898-2.
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. |
| Loop Delay Symmetry | <1 ns - ensures minimal signal skew between CANH and CANL, critical for CAN FD bit timing integrity. |
| Bus Leakage Current (Power-down) | <10 µA - preserves battery life in always-on automotive modules during sleep states. |
| ESD Robustness (CANH/CANL) | ±10 kV HBM - eliminates need for external TVS diodes in most automotive harness environments. |
| Operating Supply Voltage | 4.75–5.25 V - compatible with standard 5 V automotive LDO rails and tolerant of battery transients. |
| Thermal Shutdown Threshold | 170–190 °C - protects against latch-up during sustained overcurrent or ambient overheating. |
| AEC-Q100 Qualification | Grade 1 (−40 °C to +125 °C junction) - validated for under-hood ECU placement per automotive reliability standards. |
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 VCC; driven low for dominant bus state. |
| 2 GND | Ground reference | Primary return path for VCC, CANH, and CANL; connects to PCB ground plane for EMC stability. |
| 3 VCC | Transmitter supply | 5 V nominal supply; requires 1 µF decoupling capacitor to GND for transient suppression. |
| 4 RxD | Receive data output | CMOS-level output; low during dominant bus state, high during recessive - directly interfaces MCU CAN controller RX pin. |
| 5 NRM | Receive-only mode control | Active-low input; pulls low to disable transmitter while preserving receiver functionality for passive monitoring. |
| 6 CANL | CAN bus low I/O | Differential bus terminal; bidirectional analog node tied to termination resistor network at bus ends. |
| 7 CANH | CAN bus high I/O | Differential bus terminal; paired with CANL to form 120 Ω characteristic impedance transmission line. |
| 8 NEN | Enable control | Active-low master enable; must be low for normal or receive-only operation; high forces power-down state. |
Key Features
| Feature | Design Value |
|---|---|
| VeLIO Certification | Validated interoperability with other vehicle LAN components per OEM-specific VeLIO test suite. |
| No External Common Mode Choke Required | EME reduction via optimized transmitter/receiver symmetry meets CISPR 25 Class 5 limits without added BOM cost or board space. |
| TxD Time-out Function | Automatically disables driver after programmable timeout if TxD remains low, preventing bus lock-up during MCU faults. |
| Low-Power Modes | Three configurable states: Normal (full TX/RX), Receive-only (TX disabled), Power-save (reduced current draw with wake-on-CAN capability). |
| ISO 7637-2 Transient Protection | Withstands load dump (±100 V), jump start (+16 V), and reverse battery (−14 V) events without external clamping circuitry. |
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 TJA1145ATK/0Z | Integrated wake-up comparator and LIN-compatible standby mode; slightly higher quiescent current (15 µA vs. 10 µA) in power-down. | Better suited for gateways requiring multi-protocol wake-up; less optimized for pure CAN FD timing symmetry. | Select when LIN coexistence or enhanced wake-up sensitivity is required over strict 5 MBit/s FD margin. |
| ST TSN8101BTR | Lower ESD rating (±8 kV HBM on CANH/CANL); no VeLIO certification; supports only up to 2 MBit/s classical CAN (not CAN FD). | Limited to legacy CAN networks; not qualified for new CAN FD designs requiring >1 MBit/s or AEC-Q100 Grade 1. | Use only in cost-sensitive, non-FD, non-VeLIO automotive modules where 5 MBit/s and ±10 kV ESD are not required. |
Compared with TJA1145ATK/0Z and TSN8101BTR, the TLE9350SJXTMA1 uniquely combines 5 MBit/s CAN FD support, ±10 kV HBM ESD, VeLIO certification, and <10 µA power-down leakage - making it the only option qualified for next-generation high-bandwidth, safety-critical automotive domains.

FAQ
What is the maximum supported CAN FD data rate for TLE9350SJXTMA1?
The TLE9350SJXTMA1 supports CAN FD data rates up to 5 MBit/s, verified under ISO 11898-2:2016 test conditions with loop delay symmetry <1 ns. Performance depends on network topology and cable length; full 5 MBit/s is achievable in short-bus configurations (≤1 m stubs, ≤10 m trunk) with proper termination.
Does TLE9350SJXTMA1 require an external common mode choke?
No. The device achieves CISPR 25 Class 5 EME compliance without external common mode chokes due to intrinsic transmitter/receiver symmetry and optimized bus drive characteristics. This is validated per VeLIO test requirements and confirmed in Infineon's application note AN478.
How does the TxD time-out function operate?
The TxD time-out monitors the TxD input duration: if held low beyond ~1.5 ms (typical), the transmitter automatically disables to prevent bus dominance. Recovery occurs upon TxD high-to-low transition or NEN/NRM pin reconfiguration. Timeout duration is fixed and not user-programmable.
Is TLE9350SJXTMA1 qualified for under-hood automotive use?
Yes. It is AEC-Q100 qualified for Grade 1 (−40 °C to +125 °C junction temperature), tested per ISO 7637-2 for load dump and jump-start transients, and certified for VeLIO interoperability - meeting all requirements for under-hood ECU deployment per major OEM specifications.
