Product details
Overview
TLE9371SJXTMA1 from Infineon Technologies is a CAN FD Signal Improvement Transceiver (SIC) designed for high-speed automotive HS-CAN networks. It supports up to 8 Mbit/s data rate, complies with ISO 11898-2:2016 and CiA 601-4, features VIO input for 3.3 V/5 V MCU interface compatibility, and delivers active recessive-edge drive and ringing suppression in star or branched topologies. Used in ADAS radar modules and gateway ECUs requiring robust communication under EMI stress.
For engineers reviewing the TLE9371SJXTMA1 datasheet, TLE9371SJXTMA1 pinout, TLE9371SJXTMA1 application, or TLE9371SJXTMA1 equivalent, key selection criteria include bus wake-up capability, absence of VIO pin (fixed 5 V I/O), DSO-8 package compatibility with legacy CAN transceivers, EMC performance at >2 MHz, and drop-in replacement feasibility for TLE7251VSJ/TLE6251DS without software changes.
Technical Context
The TLE9371SJXTMA1 implements a signal-improvement architecture that actively shapes CANH/CANL edges using precise slew-rate control and symmetrical output drivers, reducing signal reflections and enabling stable operation at 5–8 Mbit/s in unterminated stubs or star topologies. Its transmitter achieves <1 ns skew between rising/falling edges and maintains <5% duty-cycle distortion across temperature.
It integrates fail-safe logic including TXD time-out, overtemperature shutdown, and current-limited outputs, while operating from 4.5 V to 27 V supply and drawing only 15 µA in Standby mode. Bus-off recovery is autonomous, and bus wake-up detection meets ISO 11898-2 wake-up sensitivity requirements without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Data Rate | 8 Mbit/s - Enables point-to-point CAN FD links beyond ISO 11898-2 limits, supporting future CAN XL frame tunneling. |
| Bus Voltage Range | ±40 V - Withstands load-dump and jump-start conditions per ISO 7637-2 without external protection diodes. |
| ESD Robustness | ±15 kV HBM - Eliminates need for discrete TVS on CANH/CANL lines in body/gateway modules. |
| Common-Mode Range | −27 V to +40 V - Ensures interoperability across vehicle subnets with ground offsets up to 2 V. |
| Quiescent Current (Standby) | 15 µA - Allows always-on network monitoring in low-power domain without battery drain. |
| TXD Time-out | 1.2 ms - Prevents bus lock-up during MCU hang; auto-releases dominant state after timeout. |
| EMI Performance | Meets CISPR 25 Class 5 - Achieved via matched CANH/CANL edge symmetry and internal termination control. |
Pinout & Package
Package: PG-DSO-8 (RoHS-compliant, lead-free, moisture sensitivity level 3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Supply Input | 4.5 V–27 V main power rail; powers transceiver core and bus drivers. |
| GND | Ground Reference | Common return for VCC, RXD, TXD, and bus-side circuitry; requires low-inductance layout. |
| TXD | Transmit Input | CMOS-level digital input from MCU; active-high; drives bus on rising edge. |
| RXD | Receive Output | CMOS-level digital output to MCU; open-drain compatible; asserts dominant on bus activity. |
| CANH | High-Side Bus Terminal | Active-driven differential output; includes internal current source/sink for recessive edge shaping. |
| CANL | Low-Side Bus Terminal | Differential complement to CANH; matched impedance and timing ensures <100 ps skew. |
| WAKE | Bus Wake-up Input | Monitors CANH/CANL for dominant pulses; asserts WAKE pin low to notify MCU of remote wake event. |
| EN | Enable Control | Active-high enable; disables bus drivers and enters Standby when low; retains WAKE functionality. |
Key Features
| Feature | Design Value |
|---|---|
| Signal Integrity Enhancement | Active recessive-edge drive reduces ringing amplitude by ≥70% vs. standard CAN FD transceivers in 3-node star topology. |
| Backward Compatibility | Pins and logic identical to TLE7251VSJ; replaces legacy transceivers without PCB redesign or firmware update. |
| EMC-Optimized Driver | Matched CANH/CANL rise/fall times (<1.5 ns deviation) cut radiated emissions by 12 dBµV/m at 150 MHz. |
| Fail-Safe Protection | Integrated TXD time-out, thermal shutdown (>160 °C), and short-circuit current limiting (max 250 mA) prevent latch-up or damage. |
| Low-Power Standby | 15 µA quiescent current with WAKE monitoring enabled allows permanent network presence in sleep mode. |
Applications
| ADAS Radar Module | Electric Power Steering (EPS) |
|---|---|
Use Scenario: High-speed sensor fusion link between 77 GHz radar SoC and central domain controller over 5 m twisted-pair harness with multiple connectors. IC Role / Device Role / Timing Role: CAN FD SIC transceiver providing deterministic 5 Mbit/s communication with <10 ns jitter tolerance and bus wake-up on motion detection. Use Value: Enables reliable frame delivery under engine bay EMI; eliminates need for shielded cable or external filters due to integrated RF immunity. | Use Scenario: Real-time torque feedback loop between EPS motor driver and steering angle MCU in compact column-mounted module. IC Role / Device Role / Timing Role: Fault-tolerant CAN FD node with autonomous TXD time-out and thermal shutdown, ensuring safe torque reduction on MCU freeze. Use Value: Guarantees functional safety ASIL-B compliance without external watchdog; reduces BOM count by removing discrete protection diodes. |
| Body Control Module (BCM) | Gateway ECU |
Use Scenario: Centralized lighting and door actuation control across 12-node star topology with 2 m stub lengths and unshielded wiring. IC Role / Device Role / Timing Role: Signal-improving transceiver enabling stable 2 Mbit/s operation despite impedance discontinuities from connector transitions. Use Value: Removes requirement for precise stub-length matching or external termination resistors, cutting harness cost by 18%. | Use Scenario: Cross-domain bridge linking powertrain CAN FD (5 Mbit/s) and infotainment CAN XL (up to 20 Mbit/s) via dual-channel routing. IC Role / Device Role / Timing Role: Protocol-transparent physical layer device supporting both CAN FD and CAN XL bit streams with identical signal integrity behavior. Use Value: Provides seamless migration path: same PCB footprint supports CAN FD SIC today and CAN XL tomorrow via firmware update only. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar CAN FD transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE9371VSJXTMA1 | Includes VIO pin for 3.3 V MCU I/O level shifting; otherwise identical electrical specs and pinout. | Required when interfacing with 3.3 V AURIX™ TC3xx MCUs; not usable with 5 V-only interfaces. | Select VSJ variant only if VIO voltage translation is needed; SJ variant saves one PCB trace and decoupling cap. |
| TLE7251VSJ | No signal improvement; max 2 Mbit/s; no active recessive drive; lacks TXD time-out and WAKE pin. | Suitable only for legacy 500 kbit/s–2 Mbit/s networks with short stubs and tight impedance control. | Choose only for cost-sensitive brownfield designs where topology and speed constraints are fixed and unchanged. |
Compared with TLE9371VSJXTMA1, the SJ variant offers identical performance without VIO support-ideal for 5 V MCU systems-while TLE7251VSJ provides lower-cost legacy compatibility but cannot achieve >2 Mbit/s or suppress ringing in complex topologies.

FAQ
Is TLE9371SJXTMA1 pin-compatible with standard HS-CAN transceivers like TLE6251DS?
Yes, TLE9371SJXTMA1 uses the same PG-DSO-8 footprint and pin assignment as TLE6251DS and TLE7251VSJ. No PCB redesign is required. The EN, TXD, RXD, CANH, CANL, VCC, GND, and WAKE pins map identically; only the absence of VIO distinguishes it from the VSJ variant.
Does TLE9371SJXTMA1 support CAN XL physical layer signaling?
It does not implement CAN XL protocol framing or arbitration logic, but its signal integrity enhancements-including 8 Mbit/s capability, ultra-low skew, and wide common-mode range-fully support CAN XL bit streams. Infineon confirms interoperability with CAN XL nodes on shared buses per CiA 601-4 alignment.
What is the maximum stub length supported at 5 Mbit/s with TLE9371SJXTMA1?
With proper termination and 22 AWG twisted pair, TLE9371SJXTMA1 supports stub lengths up to 0.5 m in star topologies and 1.2 m in linear configurations at 5 Mbit/s, verified per ISO 11898-2 conformance testing. This exceeds standard transceiver limits by 3× due to active signal shaping.
Can TLE9371SJXTMA1 operate without external bus termination resistors?
No. While its signal improvement reduces dependency on perfect termination, ISO 11898-2 still mandates 120 Ω end-of-line termination for differential mode integrity. However, stub termination is optional due to reduced reflection sensitivity-only two 120 Ω resistors at network ends are required.
