Product details
Overview
TLE9250VSJXUMA1 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 HS CAN protocol controllers and automotive bus networks. 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 VCC = 4.5–5.5 V and VIO = 3.0–5.5 V for engine control units and chassis modules.
For engineers reviewing the TLE9250VSJXUMA1 datasheet, TLE9250VSJXUMA1 pinout, TLE9250VSJXUMA1 application, or TLE9250VSJXUMA1 equivalent, key selection criteria include guaranteed loop delay symmetry for CAN FD timing integrity, low EME emission enabling choke-free layout, fail-safe TxD time-out and overtemperature protection, and dual-package availability (PG-DSO-8) with AEC-Q100 qualification for automotive deployment.
Technical Context
The TLE9250VSJXUMA1 implements a fully differential transmitter with matched CANH/CANL rise/fall times and optimized receiver delay symmetry to ensure <10 ns loop delay mismatch-critical for reliable 5 MBit/s CAN FD frame sampling. Its internal mode controller manages Normal, Forced-Receive-Only, Power-Save, and Power-Down states via the NEN pin and VCC undervoltage detection.
It integrates VIO-referenced digital I/O (TxD, RxD, NEN) with internal pull-ups, separate VCC-supplied analog driver stage, and bus-biasing circuitry that isolates the CANH/CANL lines during power-down to present near-zero bus load. Thermal shutdown activates at 170–190 °C with 5–20 K hysteresis, and short-circuit protection covers CANH/CANL faults to ground, battery, VCC, and VIO.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bus Data Rate | Up to 5 MBit/s - enables full CAN FD payload transmission without signal integrity degradation. |
| VIO Supply Range | 3.0–5.5 V - allows direct interfacing with 3.3 V or 5 V microcontrollers without level-shifting circuitry. |
| ESD Robustness | ±8 kV HBM on CANH/CANL - eliminates need for external TVS diodes in most automotive harness environments. |
| Common Mode Range | −40 V to +40 V - ensures reliable operation under severe automotive load-dump and jump-start conditions. |
| Thermal Shutdown | 170–190 °C activation - protects silicon during sustained overcurrent or ambient overheating in under-hood ECUs. |
| Power-Down Bus Leakage | <1 µA - maintains HS CAN network integrity by minimizing parasitic loading when node is inactive. |
| Supply Current (Normal) | 45 mA max at 5 V - supports low-power domain partitioning in multi-node gateway designs. |
Pinout & Package
Supplied in PG-DSO-8 package (RoHS-compliant, halogen-free), with exposed thermal pad connected to PCB ground plane for enhanced thermal dissipation in engine bay applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 TxD | Transmit Data Input | CMOS-compatible input with internal VIO-referenced pull-up; drives dominant state when logic low. |
| 2 GND | Ground Reference | Analog/digital common return; must be low-inductance connection to minimize EMI coupling. |
| 3 VCC | Transmitter Supply | 4.5–5.5 V analog supply for CAN driver stage; requires 100 nF decoupling capacitor to GND. |
| 4 RxD | Receive Data Output | CMOS output referenced to VIO; logic low indicates dominant bus state. |
| 5 VIO | Digital Supply Voltage | 3.0–5.5 V supply setting logic threshold and output levels; requires 100 nF decoupling capacitor. |
| 6 CANL | CAN Bus Low | Differential bus terminal; sinks current during dominant state; rated for −40 V to +40 V common-mode stress. |
| 7 CANH | CAN Bus High | Differential bus terminal; sources current during dominant state; rated for −40 V to +40 V common-mode stress. |
| 8 NEN | Not Enable Input | Active-low mode control pin with internal VIO pull-up; drives Normal mode when pulled low. |
Key Features
| Feature | Design Value |
|---|---|
| Loop Delay Symmetry | Guaranteed ≤10 ns mismatch between CANH/CANL edge transitions - ensures accurate bit sampling at 5 MBit/s CAN FD. |
| EME Emission Profile | Meets CISPR 25 Class 5 without external common-mode choke - reduces BOM count and PCB area in ECU layouts. |
| TxD Time-Out Function | Auto-disables transmitter after 1.2 ms of continuous dominant TxD - prevents bus lockup due to MCU firmware hang. |
| Fail-Safe Short-Circuit Protection | Withstands CANH/CANL shorts to ground, battery, VCC, or VIO indefinitely - avoids latch-up or thermal runaway in fault conditions. |
| Power-Save Mode Current | 15 µA typical - enables ultra-low-power wake-on-CAN functionality in body control modules. |

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 TJA1044GT/3 | Lower ESD rating (±6 kV HBM), no VIO pin - fixed 5 V logic interface only. | Lacks voltage adaptability for 3.3 V MCUs; requires external level shifter in mixed-voltage systems. | Select when cost sensitivity outweighs design flexibility and ESD margin requirements. |
| ST TLE6250G | Legacy generation; supports only up to 1 MBit/s; no CAN FD timing symmetry guarantee. | Not suitable for CAN FD networks; limited to classical CAN in non-safety-critical subsystems. | Choose only for brownfield upgrades where bandwidth and FD compliance are not required. |

FAQ
What is the maximum CAN FD data rate supported by TLE9250VSJXUMA1?
The TLE9250VSJXUMA1 supports CAN FD data frames up to 5 MBit/s, validated through guaranteed loop delay symmetry (<10 ns mismatch) and differential signal integrity testing per ISO 11898-2:2016. This capability enables high-throughput firmware updates and real-time sensor fusion data transfer in modern automotive gateways and domain controllers.
Does TLE9250VSJXUMA1 require an external common-mode choke?
No. The TLE9250VSJXUMA1 achieves CISPR 25 Class 5 EME compliance without external common-mode chokes due to its highly symmetric transmitter architecture and optimized PCB layout guidance. This reduces bill-of-materials cost and board area, particularly valuable in space-constrained ECU modules like EPS and TCUs.
How does the TxD time-out function protect the CAN network?
The TxD time-out function disables the transmitter after 1.2 ms of continuous dominant output, preventing bus lockup if the connected microcontroller hangs or fails to toggle TxD. This autonomous hardware feature ensures network resilience without software intervention, maintaining communication integrity for other nodes during MCU faults.
Is TLE9250VSJXUMA1 qualified for automotive use?
Yes. The TLE9250VSJXUMA1 is AEC-Q100 qualified (Grade 1: −40 °C to +125 °C ambient, junction up to +150 °C), with extended validation against ISO 7637-2/3 and SAE J2962-2 transient immunity standards. It is approved for use in engine control, transmission, and chassis systems per OEM functional safety requirements.
