Infineon Technologies TLE9250VLEXUMA1

Overview

TLE9250VLEXUMA1 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 networks in automotive ECUs. It supports CAN FD data frames up to 5 MBit/s, features VIO voltage adaptation (3.3 V/5 V), and delivers ±8 kV HBM ESD robustness. Used in engine control units and electric power steering systems.

For engineers reviewing the TLE9250VLEXUMA1 datasheet, TLE9250VLEXUMA1 pinout, TLE9250VLEXUMA1 application, or TLE9250VLEXUMA1 equivalent, key selection criteria include loop delay symmetry for CAN FD timing integrity, common-mode immunity over –27 V to +40 V, fail-safe TxD time-out function, and PG-TSON-8 package compatibility with AOI inspection.

Technical Context

The TLE9250VLEXUMA1 implements a fully differential transmitter with matched CANH/CANL output paths to ensure <1 ns loop delay asymmetry-critical for reliable CAN FD bit rates up to 5 MBit/s. Its receiver uses a normal-mode architecture with internal VCC/2 reference, enabling stable dominant/recessive detection across wide common-mode voltage ranges (–27 V to +40 V).

Mode control is managed via the NEN pin (active-low enable), supporting Normal, Forced-Receive-Only, Power-Save, and Power-Down states. 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.

FAQ

What is the maximum CAN FD data rate supported by TLE9250VLEXUMA1?

The TLE9250VLEXUMA1 guarantees loop delay symmetry enabling reliable CAN FD data phase operation up to 5 MBit/s. This is validated per ISO 11898-2 (2016) and confirmed in Infineon's interoperability test reports. Performance depends on network topology and stub length, but the device itself supports full 5 MBit/s signaling without external equalization or timing compensation.

Does TLE9250VLEXUMA1 require an external common-mode choke?

No. The TLE9250VLEXUMA1 achieves very low electromagnetic emission (EME) through precisely matched transmitter output impedance and timing symmetry, allowing compliance with CISPR 25 Class 5 radiated emissions limits without a common-mode choke. This is verified in Infineon's EMC test reports and application notes for TSON8 layout configurations.

How does the VIO pin function in TLE9250VLEXUMA1?

The VIO pin supplies the digital I/O interface (TxD, RxD, NEN) and sets the logic threshold for those pins. It accepts 3.0 V to 5.5 V, enabling direct connection to either 3.3 V or 5 V microcontrollers without external level translation. VIO must be decoupled with a 100 nF capacitor to GND, and its voltage defines the high/low recognition levels for all digital signals.

Is TLE9250VLEXUMA1 qualified for automotive use?

Yes. The TLE9250VLEXUMA1 is qualified per AEC-Q100 Grade 0 (–40 °C to +150 °C ambient), with full validation including HTOL, TC, UHAST, and ESD testing. It is certified for engine bay and transmission control applications, and its PG-TSON-8 package meets solder-joint reliability requirements for automated optical inspection in high-volume automotive assembly.
