Product details
Overview
TLE8250SJXUMA1 from Infineon Technologies is a high-speed CAN transceiver compliant with ISO 11898-2:2016, serving as the physical-layer interface between CAN protocol controllers and HS CAN bus in automotive ECUs. It supports CAN FD data rates up to 2 MBit/s, features guaranteed loop delay symmetry ≤255 ns, operates across extended VCC supply range (4.5 V to 27 V), and provides CANH/CANL short-circuit protection to ground, battery, and VCC.
For engineers reviewing the TLE8250SJXUMA1 datasheet, TLE8250SJXUMA1 pinout, TLE8250SJXUMA1 application, or TLE8250SJXUMA1 equivalent, key selection criteria include ESD robustness (IEC61000-4-2 ±8 kV contact), receive-only and power-save modes, low bus leakage current (<1 µA in power-down), and VeLIO certification for Japanese vehicle interoperability.
Technical Context
The TLE8250SJXUMA1 implements a differential HS CAN physical layer with symmetrical transmitter slew rates and matched internal propagation paths to ensure loop delay symmetry ≤255 ns-critical for reliable CAN FD frame integrity at 2 MBit/s. Its Smart Power Technology (SPT) enables integrated overtemperature protection, undervoltage lockout, and fail-safe TxD time-out functionality.
Three configurable operating modes-normal (transmit + receive), receive-only (RX active, TX disabled), and power-save (TX/RX off, RxD high, high-impedance bus)-are selected via dual logic inputs (NEN/NRM). The device maintains passive bus behavior in power-down with <1 µA CANH/CANL leakage and supports mixed-supply networks via wide 4.5–27 V VCC tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 2 MBit/s - enables full CAN FD high-speed data frames without signal integrity degradation. |
| Loop Delay Symmetry | ≤255 ns - ensures precise bit timing alignment between TxD input and RxD output for arbitration-safe operation. |
| VCC Supply Range | 4.5 V to 27 V - supports direct connection to automotive battery rails including cold-crank (4.5 V) and load-dump (27 V) conditions. |
| Bus Leakage Current | <1 µA in power-down - preserves network biasing integrity and prevents false wake-up in multi-node sleep states. |
| ESD Robustness | ±8 kV contact per IEC61000-4-2 - eliminates need for external TVS diodes in standard harness environments. |
| Common Mode Range | −27 V to +40 V - sustains communication during severe electromagnetic interference events like ISO 7637-2 pulse 5a. |
| Receiver Threshold | Dominant: VDiff ≥ 0.9 V; recessive: VDiff ≤ 0.5 V - guarantees noise-immune signal detection across temperature and voltage extremes. |
Pinout & Package
Package: PG-DSO-8 (RoHS-compliant, surface-mount, 8-pin exposed pad SOIC variant with thermal enhancement).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 TxD | Transmit data input | CMOS-level input from CAN controller; internal pull-up to VCC; "low" asserts dominant bus state. |
| 2 GND | Ground reference | Primary return path for VCC and bus biasing; connects to exposed thermal pad for thermal dissipation. |
| 3 VCC | Transmitter supply | Power source for driver stage; requires 100 nF decoupling capacitor to GND for EMI suppression. |
| 4 RxD | Receive data output | CMOS-level output to CAN controller; "low" during dominant bus state; high-impedance in power-save mode. |
| 5 NEN | Mode enable control | Active-low input; "low" enables normal/receive-only modes; "high" forces power-save mode. |
| 6 CANL | CAN bus low I/O | Differential bus terminal; driven low during dominant state; floats in power-save mode. |
| 7 CANH | CAN bus high I/O | Differential bus terminal; driven high during dominant state; floats in power-save mode. |
| 8 NRM | Receive-only mode select | Active-low input; "low" with NEN=low selects receive-only mode; internal pull-up to VCC. |
Key Features
| Feature | Design Value |
|---|---|
| ISO 11898-2:2016 compliance | Fully certified physical layer implementation - eliminates interoperability risk in OEM HS CAN networks. |
| VeLIO certification | Validated for Japanese vehicle LAN interoperability - meets stringent JASO/ISO conformance requirements for domestic automakers. |
| TxD time-out function | Automatic transmitter disable after prolonged dominant TxD state - prevents bus lockup due to MCU hang or software fault. |
| Overtemperature protection | Thermal shutdown at Tj > 175 °C with automatic recovery - protects against solder reflow damage and sustained overload. |
| Short-circuit proof outputs | CANH/CANL tolerant to continuous short to ground, battery, or VCC - enables robust deployment in under-hood wiring harnesses. |
Applications
| Engine Control Unit (ECU) | Electric Power Steering (EPS) |

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 |
|---|---|---|---|
| MAX3051ESA+ | Single-supply (3.3 V only), no receive-only mode, no TxD time-out, lower ESD (±2 kV) | Limited to low-voltage industrial CAN networks; unsuitable for automotive battery-rail operation or fail-safe diagnostics | Select only for cost-sensitive non-automotive 3.3 V systems where VeLIO or AEC-Q100 is not required. |
| SN65HVD230DR | 5 V supply only, no power-save mode, higher bus leakage (>5 µA), no VeLIO certification | Applicable in legacy 5 V automotive modules but lacks CAN FD support and fails ISO 11898-2:2016 loop delay spec | Use only for backward compatibility in pre-CAN FD designs; avoid for new CAN FD or Japanese-market deployments. |
Compared with MAX3051ESA+ and SN65HVD230DR, the TLE8250SJXUMA1 uniquely combines AEC-Q100 Grade 1 qualification, VeLIO certification, CAN FD–ready 2 MBit/s capability, and three-mode configurability-making it the sole choice for next-generation Japanese and global OEM chassis and powertrain networks requiring fail-safe bus operation.

FAQ
What is the maximum CAN FD data rate supported by the TLE8250SJXUMA1?
The TLE8250SJXUMA1 supports CAN FD data rates up to 2 MBit/s, validated by guaranteed loop delay symmetry ≤255 ns and compliance with ISO 11898-2:2016 physical layer timing requirements. This enables full utilization of CAN FD's flexible data phase without signal distortion or arbitration errors.
Does the TLE8250SJXUMA1 require external bus termination resistors?
Yes-the TLE8250SJXUMA1 does not integrate bus termination. A 120 Ω resistor must be placed across CANH and CANL at each end of the HS CAN bus segment to maintain proper impedance matching and minimize reflections at data rates up to 2 MBit/s.
How does the TxD time-out function protect the CAN network?
The TxD time-out function disables the transmitter if TxD remains low for longer than 250 µs, preventing indefinite bus dominance caused by MCU lockup or software faults. This ensures other nodes retain arbitration access and avoids network-wide communication failure.
Is the TLE8250SJXUMA1 compatible with 3.3 V CAN controllers?
Yes-the TLE8250SJXUMA1 accepts 3.3 V CMOS logic levels on TxD and delivers 3.3 V–compatible CMOS output on RxD, despite its 4.5–27 V VCC supply. Logic thresholds are independent of VCC, ensuring interoperability with both 3.3 V and 5 V microcontrollers.
