Infineon Technologies TLE9252VSKXUMA1

Overview

TLE9252VSKXUMA1 from Infineon Technologies is a high-speed CAN FD transceiver compliant with ISO 11898-2:2016 and SAE J2284-4/-5, supporting data rates up to 5 Mbit/s. It serves as the physical layer interface between a CAN protocol controller and the HS CAN bus, featuring autonomous bus biasing, dual power supply (VBAT/VCC), and fail-safe functions including TxD time-out, RxD recessive clamping, and overtemperature shutdown.

For engineers reviewing the TLE9252VSKXUMA1 datasheet, TLE9252VSKXUMA1 pinout, TLE9252VSKXUMA1 application, or TLE9252VSKXUMA1 equivalent, key selection criteria include loop delay symmetry for CAN FD timing integrity, ±10 kV HBM ESD robustness, sleep-mode current ≤25 µA, and WUP filter time programmability (0.5–1.8 µs) for OEM-specific wake-up compliance.

Technical Context

The TLE9252VSKXUMA1 implements a fully differential transmitter/receiver architecture with matched propagation delays on CANH and CANL paths, enabling precise loop delay symmetry (<10 ns typical) critical for reliable CAN FD frame reception at 5 Mbit/s. Its mode control logic supports four operational states-Normal, Receive-only, Stand-by, and Sleep-with autonomous transitions triggered by EN, NSTB, and WAKE inputs.

It integrates dual-supply regulation (VBAT for robust cranking support, VCC for transmitter operation) and voltage-level shifting via VIO (3.3 V or 5 V compatible), while NERR provides combined failure diagnosis and wake-up status indication. The open-drain INH output enables external circuit control during low-power modes.

FAQ

What is the maximum CAN FD data rate supported by the TLE9252VSKXUMA1?

The TLE9252VSKXUMA1 supports up to 5 Mbit/s, verified per ISO 11898-2:2016 Annex D test procedures. This rate is achievable with guaranteed loop delay symmetry <10 ns and matched CANH/CANL rise/fall times, enabling error-free transmission of CAN FD frames with 64-byte payloads in automotive networks.

How does the TLE9252VSKXUMA1 handle battery cranking conditions?

It uses a dual-supply architecture: VBAT (−0.3 V to 40 V) powers internal biasing and wake-up circuitry, while VCC (−0.3 V to 6.0 V) supplies the transmitter. During cranking (VBAT down to ~3 V), the device remains functional in Normal or Stand-by Mode, and retains Sleep Mode wake-up capability via WAKE pin.

Is the TLE9252VSKXUMA1 pin-compatible with earlier Infineon CAN transceivers like TLE6250?

No. The TLE9252VSKXUMA1 has 14 pins and distinct pin assignments (e.g., separate VBAT, VIO, INH, NERR, WAKE), whereas TLE6250 is an 8-pin device with different mode control and diagnostic signaling. Migration requires PCB layout revision and firmware adaptation for new pin functions and timing behavior.

What diagnostic capabilities does the NERR pin provide?

NERR is an active-low, open-drain output that indicates undervoltage (on VBAT, VCC, or VIO), overtemperature shutdown, TxD time-out, or local/wake-up events. Its pulse width and timing distinguish fault types per datasheet Table 12, enabling MCU-based root-cause analysis without additional sensors.
