Product details
Overview
TLE9250LEXUMA1 from Infineon is a high-speed CAN FD transceiver compliant with ISO 11898-2:2016 and SAE J2284-4/-5, serving as the physical layer interface between microcontroller CAN controllers and automotive HS CAN bus networks. It supports data rates up to 5 MBit/s, features ±8 kV HBM ESD robustness, operates across 4.5–5.5 V VCC, and delivers guaranteed loop delay symmetry for reliable FD frame transmission in engine control units and chassis modules.
For engineers reviewing the TLE9250LEXUMA1 datasheet, TLE9250LEXUMA1 pinout, TLE9250LEXUMA1 application, or TLE9250LEXUMA1 equivalent, this device is selected for automotive-grade CAN FD node design requiring low EME, fail-safe modes (Power-save, Receive-only), and AEC-Q100 qualified operation without external common-mode chokes.
Technical Context
The TLE9250LEXUMA1 implements a fully differential transmitter with matched CANH/CANL output timing and a high-symmetry receiver path optimized for CAN FD's fast bit rates. Its internal mode control logic interprets NEN and NRM pin states to enable Normal, Receive-only, Power-save, and Power-down states - each with defined bus leakage (<1 µA in power-down) and wake-up latency.
It integrates fail-safe functions including TxD time-out (prevents bus lock-up), overtemperature shutdown (170–190 °C trip), short-circuit protection to battery/GND/VCC, and robust ESD immunity (±11 kV IEC 61000-4-2 on CANH/CANL). The transceiver remains passive on bus when unpowered, minimizing network loading.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bus Data Rate | Up to 5 MBit/s - enables CAN FD high-speed data phase in automotive ADAS and powertrain networks. |
| VCC Supply Range | 4.5 V to 5.5 V - compatible with standard automotive 5 V rail; supports extended cold-crank conditions down to 4.5 V. |
| ESD Robustness | ±8 kV HBM, ±11 kV IEC 61000-4-2 - eliminates need for external TVS diodes on CANH/CANL in most vehicle architectures. |
| Common-Mode Range | −40 V to +40 V - ensures reliable operation under ISO 7637-2 load-dump and jump-start transients. |
| Bus Leakage (Power-down) | <1 µA - maintains HS CAN network integrity by presenting near-ideal open-circuit behavior when disabled. |
| Thermal Shutdown | 170–190 °C trip, 150 °C hysteresis - protects against thermal runaway during sustained fault conditions. |
| Mode Control Pins | NEN (active-low enable), NRM (active-low receive-only) - allow deterministic state transitions without MCU firmware dependency. |
Pinout & Package
Package: PG-TSON-8 (3.0 mm × 3.0 mm, 0.65 mm pitch), leadless, RoHS-compliant, AOI-compatible with exposed thermal pad connected to GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 TxD | Transmit Data Input | CMOS input with internal pull-up to VCC; dominant state = logic low; drives transmitter stage. |
| 2 GND | Ground Reference | Primary signal and power ground; connects to thermal pad for heat dissipation. |
| 3 VCC | Transmitter Supply | 4.5–5.5 V supply; requires 100 nF decoupling capacitor to GND at pin. |
| 4 RxD | Receive Data Output | CMOS output; dominant state = logic low; reflects bus state after receiver threshold detection. |
| 5 NRM | Not Receive-Only Input | Active-low control; pulls low to enter Receive-only mode (transmitter disabled, receiver active). |
| 6 CANL | CAN Bus Low I/O | Differential bus terminal; "low" during dominant state; rated for −40 V to +40 V common-mode. |
| 7 CANH | CAN Bus High I/O | Differential bus terminal; "high" during dominant state; matched delay to CANL for FD symmetry. |
| 8 NEN | Not Enable Input | Active-low master enable; pulls low to activate Normal or Receive-only mode; high = Power-down. |
Key Features
| Feature | Design Value |
|---|---|
| Loop Delay Symmetry | Guaranteed <±5 ns mismatch between CANH/CANL rise/fall paths - essential for 5 MBit/s CAN FD timing margin. |
| EME Performance | Meets CISPR 25 Class 5 without common-mode choke - reduces BOM cost and PCB area in ECU designs. |
| Fail-Safe TxD Time-out | Auto-disables transmitter after ~1.5 ms of continuous dominant TxD - prevents bus lock-up during MCU hang. |
| Power-Save Mode | Draws <15 µA while maintaining RxD functionality and wake-up capability via bus activity - extends sleep-mode battery life. |
| AEC-Q100 Qualification | Qualified to Grade 1 (−40 °C to +125 °C ambient) - validated for engine bay and transmission control applications. |
Applications
| Engine Control Unit (ECU) | Electric Power Steering (EPS) |
|---|---|

IC Role / Device Role / Timing Role: Fail-safe CAN interface with TxD time-out and overtemperature protection to prevent bus dominance faults. Use Value: Integrated short-circuit proofing to battery/GND/VCC and thermal shutdown prevent single-point failures affecting steering assist. |
| Transmission Control Unit (TCU) | Chassis Control Module |
Use Scenario: High-bandwidth gearshift coordination between TCU, engine ECU, and brake control module during automated shifting. IC Role / Device Role / Timing Role: CAN FD transceiver supporting multi-frame UDS diagnostics and real-time actuator commands. Use Value: 5 MBit/s data phase enables faster flash programming and diagnostic response vs legacy CAN 1 MBit/s. |
Use Scenario: Distributed chassis domain controller aggregating signals from ABS, ESC, and suspension sensors over HS CAN backbone. IC Role / Device Role / Timing Role: Network node with Power-save mode activated during vehicle sleep to maintain wake-on-CAN capability. Use Value: <15 µA sleep current and bus-activity wake-up reduce parasitic drain below 50 µA - critical for 14-day key-off battery hold. |
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 |
|---|---|---|---|
| MAX33042EASA+ | Lower ESD rating (±15 kV IEC 61000-4-2), no integrated TxD time-out, wider VCC range (3.0–5.5 V) | Preferred in industrial CAN FD nodes where extended voltage range matters more than automotive transient immunity | Select when operating outside AEC-Q100 environments and needing broader supply flexibility |
| SN65HVD256DR | Legacy CAN FD transceiver; only supports up to 2 MBit/s, no Power-save mode, ±8 kV HBM only | Suitable for cost-sensitive body electronics where 5 MBit/s FD is unnecessary | Choose for non-safety-critical LIN/CAN gateways or retrofit applications with existing 2 MBit/s infrastructure |
Compared with MAX33042EASA+ and SN65HVD256DR, the TLE9250LEXUMA1 uniquely combines AEC-Q100 Grade 1 qualification, 5 MBit/s FD support, integrated fail-safes (TxD time-out, thermal shutdown), and ultra-low EME - making it the only option qualified for next-generation powertrain and chassis CAN FD domains.

FAQ
What is the maximum CAN FD data rate supported by the TLE9250LEXUMA1?
The TLE9250LEXUMA1 supports CAN FD data frames up to 5 MBit/s, verified under ISO 11898-2:2016 test conditions with guaranteed loop delay symmetry. This performance is achievable in typical automotive harness configurations up to 20 m length and depends on network topology and termination. It exceeds the 2 MBit/s limit of legacy transceivers like the SN65HVD256.
Does the TLE9250LEXUMA1 require an external common-mode choke?
No - the TLE9250LEXUMA1 achieves CISPR 25 Class 5 emission compliance without an external common-mode choke due to its optimized transmitter symmetry and low electromagnetic emission (EME) design. This is confirmed in Infineon's EMC test reports and application note AN478, reducing BOM count and PCB space in ECU layouts.
How does the TxD time-out function protect the CAN network?
The TxD time-out disables the transmitter output after approximately 1.5 ms of continuous dominant state on the TxD pin, preventing bus lock-up if the MCU freezes mid-transmission. This feature is hardware-based, independent of firmware, and resets automatically upon TxD returning to recessive - ensuring network recovery without system reset.
Is the TLE9250LEXUMA1 pin-compatible with earlier Infineon CAN transceivers?
No - the TLE9250LEXUMA1 uses the PG-TSON-8 package with a unique 8-pin layout (including dedicated NRM and NEN pins), differing from the PG-DSO-8 footprint of TLE6250 or TLE8250. Pin mapping and mode control logic are not interchangeable; board redesign is required for migration from legacy devices.
