Product details
Overview
TLE9371VSJXTMA1 from Infineon Technologies is a high-speed CAN FD transceiver designed for automotive HS-CAN physical layer interfacing between microcontrollers and differential bus networks. It supports data rates up to 8 Mbit/s, complies with ISO 11898-2:2024 and SAE J2284-4/-5, features VIO voltage adaptation (3.3 V/5 V), standby mode with <10 µA quiescent current on VIO, and integrated wake-up indication on RxD - deployed in gateway modules and ADAS radar subsystems.
For engineers reviewing the TLE9371VSJXTMA1 datasheet, TLE9371VSJXTMA1 pinout, TLE9371VSJXTMA1 application, or TLE9371VSJXTMA1 equivalent, key selection criteria include loop delay symmetry for CAN FD frame integrity, ESD robustness (±8 kV HBM), fail-safe features (TxD timeout, overtemperature protection), and RoHS-compliant PG-DSO-8 packaging suitable for AEC-Q100-qualified automotive designs.
Technical Context
The TLE9371VSJXTMA1 implements a dual-receiver architecture: a normal-mode receiver for active communication and a low-power receiver enabling bus wake-up detection while in standby. Its transmitter uses symmetric drive circuitry to minimize differential skew between CANH and CANL edges, ensuring <1 ns loop delay asymmetry critical for reliable 5–8 Mbit/s CAN FD data frames.
It integrates dedicated fault management including short-circuit protection to battery, ground, VCC, and VIO; undervoltage lockout on VCC; and thermal shutdown at >150 °C. The STB pin controls mode transitions with internal pull-up to VIO, and RxD asserts wake-up logic during valid bus patterns without requiring external supervision.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bus Data Rate | Up to 8 Mbit/s - enables high-throughput CAN FD payloads in radar and ECU applications without signal integrity degradation. |
| Loop Delay Symmetry | <1 ns - ensures matched propagation delays between CANH/CANL paths, preserving bit timing accuracy for FD arbitration and data phases. |
| VIO Supply Range | 3.0 V to 5.5 V - allows direct interface with 3.3 V or 5 V microcontrollers without level-shifting circuitry. |
| Standby Quiescent Current | <10 µA on VIO - minimizes system power draw during sleep while retaining bus wake-up capability. |
| ESD Robustness | ±8 kV HBM, IEC 61000-4-2 Level 4 - eliminates need for external TVS diodes in harsh automotive environments. |
| Common-Mode EME | Meets CISPR 25 Class 5 without choke - reduces BOM count and PCB area by removing common-mode filter components. |
| Short-Circuit Protection | CANH/CANL protected against battery, ground, VCC, and VIO faults - prevents latch-up and damage during wiring faults or assembly errors. |
Pinout & Package
Supplied in a halogen-free, RoHS-compliant PG-DSO-8 package (exposed thermal pad, 8-pin SOIC variant with gull-wing leads).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 TxD | Transmit data input | CMOS-compatible serial input from MCU; internal pull-up to VIO; dominant state = low. |
| 2 GND | Ground reference | Primary return path for VIO, VCC, and bus biasing; must be low-inductance connection to system ground plane. |
| 3 VCC | Transmitter supply | 12 V nominal supply for CAN driver stage; can be disabled in standby to reduce total system quiescent current. |
| 4 RxD | Receive data output | CMOS-compatible serial output to MCU; "low" = dominant bus state; also signals wake-up via pulse on bus activity. |
| 5 VIO | Digital interface supply | 3.3 V or 5 V supply for logic interface and low-power receiver; decoupled with 100 nF capacitor. |
| 6 CANL | CAN bus low terminal | Differential bus I/O; driven low during dominant state; internally biased to VCC/2 in recessive state. |
| 7 CANH | CAN bus high terminal | Differential bus I/O; driven high during dominant state; complements CANL for noise-immune signaling. |
| 8 STB | Standby control input | Active-low enable; internal pull-up to VIO; "low" = normal operation, "high" = standby with VCC off option. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-receiver wake-up architecture | Enables bus-initiated wake-up from standby without VCC applied - maintains network responsiveness while cutting system power. |
| Asymmetric fault-tolerant bus protection | Withstands simultaneous shorts of CANH/CANL to battery, ground, VCC, and VIO - eliminates single-point failure modes in vehicle harnesses. |
| Integrated TxD timeout function | Automatically disables transmitter after 1.5 ms of continuous dominant state - prevents bus lockup due to MCU hang or software error. |
| Optimized EME emission profile | Passes CISPR 25 Class 5 radiated emissions testing across 150 kHz–108 MHz without external common-mode choke - simplifies layout and certification. |
| AEC-Q100 qualified Grade 1 | Rated for −40 °C to +125 °C ambient operation with full parametric validation - meets functional safety requirements for powertrain and ADAS systems. |

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 selective wake-up via WAKE pin; lower max data rate (5 Mbit/s); requires external VIO regulator for 3.3 V operation. | Better suited for gateways needing selective node activation; less optimal for 8 Mbit/s radar links. | Select when PN-based power management is required and 5 Mbit/s suffices; avoid for time-critical FD radar backbones. |
| ST TPD4S012 | Single-channel CAN FD transceiver with integrated ESD protection only (no short-circuit or overtemperature protection); no standby mode or wake-up logic. | Limited to non-safety-critical infotainment or comfort systems where fault coverage is secondary. | Choose only for cost-sensitive, low-risk interior modules - not for powertrain, ADAS, or gateway use cases. |
Compared with TJA1145A and TPD4S012, the TLE9371VSJXTMA1 uniquely delivers 8 Mbit/s FD support with integrated fail-safes, dual-receiver wake-up, and Toyota VeLIO certification - making it the only choice for AEC-Q100-compliant radar and ECU nodes demanding full fault resilience and maximum throughput.

FAQ
What is the maximum supported CAN FD data rate for TLE9371VSJXTMA1?
The TLE9371VSJXTMA1 supports CAN FD data frames up to 8 Mbit/s, validated under ISO 11898-2:2024 and confirmed in Infineon's characterization across temperature and voltage ranges. This performance depends on network topology and termination but is achievable in typical automotive star or linear topologies with ≤30 m bus length and proper stub management.
Does TLE9371VSJXTMA1 require an external common-mode choke?
No - the device achieves CISPR 25 Class 5 radiated emissions compliance without external common-mode chokes due to its optimized driver symmetry and low electromagnetic emission (EME) design. This is verified in Infineon's EMC test reports and reflected in production board layouts used by Tier 1 suppliers for radar and ECU applications.
How does the standby mode reduce system power consumption?
In standby mode, the TLE9371VSJXTMA1 disables its VCC-powered transmitter and switches to a low-power receiver powered solely by VIO, drawing <10 µA from VIO. VCC may be turned off entirely, eliminating transmitter quiescent load - reducing total node current to ~15 µA including MCU I/O leakage, ideal for parked-vehicle battery conservation.
Is TLE9371VSJXTMA1 compatible with 3.3 V microcontrollers?
Yes - the VIO pin accepts 3.0 V to 5.5 V, enabling direct interface with 3.3 V MCUs without level shifters. Both TxD input and RxD output operate at CMOS levels referenced to VIO, and the internal pull-ups on TxD and STB are tied to VIO, ensuring logic compatibility and noise margin across voltage variants.
