Product details
Overview
TLE9250XLEXUMA1 from Infineon is a high-speed CAN transceiver compliant with ISO 11898-2 (2016) and SAE J2284-4/-5, serving as the physical layer interface between microcontrollers and HS CAN bus in automotive ECUs. It supports CAN FD data frames up to 5 MBit/s, features VIO voltage adaptation (3.3 V / 5 V), ±8 kV HBM ESD robustness, and operates across -40 °C to 150 °C junction temperature.
For engineers reviewing the TLE9250XLEXUMA1 datasheet, TLE9250XLEXUMA1 pinout, TLE9250XLEXUMA1 application, or TLE9250XLEXUMA1 equivalent, key selection criteria include guaranteed loop delay symmetry for CAN FD timing integrity, low EME enabling choke-free layout, fail-safe TxD time-out and overtemperature protection, and dual-supply flexibility via separate VCC and VIO rails.
Technical Context
The TLE9250XLEXUMA1 implements a fully differential transmitter with matched CANH/CANL output drive strength and precisely balanced propagation delays-enabling <5 MBit/s CAN FD operation without signal distortion. Its receiver includes a normal-mode path with VCC/2 reference and hysteresis for noise immunity across wide common-mode range (-40 V to +40 V).
Mode control is managed via the RM pin (internal pull-down), supporting Normal, Forced-Receive-Only, Receive-Only, and Power-down states. The transceiver enters thermal shutdown at 170–190 °C with 5–20 K hysteresis and provides short-circuit protection to ground, battery, VCC, and VIO on CANH/CANL outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Compliance | ISO 11898-2 (2016), SAE J2284-4/-5, AEC-Q100 qualified - ensures interoperability and automotive reliability. |
| Max Data Rate | 5 MBit/s - enables CAN FD fast-phase communication in engine control and ADAS networks. |
| VIO Range | 3.0 V to 5.5 V - allows direct logic-level matching to 3.3 V or 5 V microcontrollers without level shifters. |
| ESD Robustness | ±8 kV HBM (CANH/CANL), ±11 kV IEC 61000-4-2 - eliminates need for external TVS diodes in most layouts. |
| Common-Mode Range | -40 V to +40 V - maintains reliable reception under severe automotive load-dump or battery-reversal conditions. |
| Bus Leakage (Power-down) | <1 µA - minimizes standby current in sleep-mode vehicle networks. |
| Thermal Shutdown | 170–190 °C activation, 5–20 K hysteresis - prevents latch-up during sustained overtemperature events. |
Pinout & Package
Package: PG-TSON-8 (leadless, 3 mm × 3 mm, 0.65 mm pitch), RoHS-compliant and halogen-free, optimized for AOI and high-density automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 TxD | Transmit Data Input | CMOS input with internal VIO pull-up; "low" drives dominant bus state; requires clean MCU TX edge. |
| 2 GND | Ground Reference | Primary analog/digital return; must be low-inductance connection to minimize EMI coupling. |
| 3 VCC | Transmitter Supply | 4.5–5.5 V supply for CANH/CANL drivers; requires 100 nF decoupling capacitor to GND. |
| 4 RxD | Receive Data Output | CMOS output referenced to VIO; "low" = dominant, "high" = recessive; open-drain compatible. |
| 5 VIO | Digital Interface Supply | 3.0–5.5 V rail setting logic thresholds for TxD/RxD; requires 100 nF decoupling capacitor. |
| 6 CANL | CAN Bus Low Terminal | Differential bus I/O; "low" during dominant state; short-circuit protected to GND/VCC/VIO/battery. |
| 7 CANH | CAN Bus High Terminal | Differential bus I/O; "high" during dominant state; symmetric drive ensures low EME and jitter. |
| 8 RM | Receive-Only Mode Control | Active-low input with internal GND pull-down; "low" = Normal mode, "high" = Receive-only mode. |
Key Features
| Feature | Design Value |
|---|---|
| Loop Delay Symmetry | Guaranteed matching between CANH/CANL rise/fall paths enables stable 5 MBit/s CAN FD timing without external tuning. |
| EME Performance | Low electromagnetic emission eliminates need for common-mode chokes in most automotive PCB layouts. |
| VIO Voltage Adaptation | Independent 3.0–5.5 V digital supply allows seamless integration with both 3.3 V and 5 V microcontrollers. |
| TxD Time-Out Function | Automatic bus release after ~1.5 ms of continuous dominant TxD assertion - prevents bus lockup from firmware faults. |
| Fail-Safe Protection | Integrated short-circuit, overtemperature, and undervoltage protection safeguards transceiver and bus during fault conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed CAN transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP TJA1044T/3 | Lower ESD rating (±6 kV HBM), no VIO pin - uses single 5 V supply only. | Limited to 5 V MCU interfaces; less suitable for mixed-voltage domains requiring 3.3 V logic compatibility. | Select when cost sensitivity outweighs VIO flexibility and higher ESD margin is not required. |
| ST TLE6250G | Legacy device; max 1 MBit/s, no CAN FD support, wider VCC range (4.5–27 V), no TxD time-out. | Designed for classical CAN only; lacks loop delay symmetry and failsafe features needed for modern FD networks. | Choose only for brownfield designs where CAN FD upgrade is not planned and extended supply range is critical. |
Compared with NXP TJA1044T/3 and ST TLE6250G, the TLE9250XLEXUMA1 delivers superior CAN FD readiness, dual-supply adaptability, and integrated fail-safes-making it optimal for new-generation automotive ECUs targeting ASIL-B functional safety and 5 MBit/s data throughput.

FAQ
What is the purpose of the VIO pin on the TLE9250XLEXUMA1?
The VIO pin supplies the digital interface circuitry and sets the logic threshold levels for TxD input and RxD output. It accepts 3.0 V to 5.5 V, enabling direct compatibility with both 3.3 V and 5 V microcontrollers without external level-shifting components. This simplifies design in mixed-voltage automotive ECUs and reduces BOM count.
Does the TLE9250XLEXUMA1 support CAN FD, and what is its maximum bit rate?
Yes, the TLE9250XLEXUMA1 supports CAN FD with guaranteed loop delay symmetry enabling reliable operation up to 5 MBit/s in the fast phase. This capability is validated per ISO 11898-2 (2016) and confirmed in Infineon's interoperability test specification for CAN transceivers.
How does the TxD time-out function protect the CAN network?
The TxD time-out function automatically forces the transceiver into receive-only mode if the TxD input remains low for approximately 1.5 ms. This prevents firmware lockups or MCU faults from holding the bus in a dominant state indefinitely, ensuring network-level fault containment and continued communication among other nodes.
Is the TLE9250XLEXUMA1 pin-compatible with earlier Infineon CAN transceivers like TLE6250?
No, the TLE9250XLEXUMA1 uses a PG-TSON-8 package with different pin assignment (e.g., RM pin at Pin 8, VIO at Pin 5) and is not pin-compatible with the legacy PG-DSO-8 TLE6250. Migration requires PCB layout revision and validation of mode control, supply decoupling, and ESD layout practices.
