Product details
Overview
TLE8250GXUMA1 from Infineon is a high-speed CAN transceiver compliant with ISO 11898-2, serving as the physical layer interface between CAN protocol controllers and differential bus lines. It supports data rates up to 1 MBit/s, features ±40 V common-mode range, <1 µA bus leakage in Power Down mode, and integrated TxD time-out and over-temperature protection. It is deployed in engine control units for real-time fault-tolerant vehicle communication.
For engineers reviewing the TLE8250GXUMA1 datasheet, TLE8250GXUMA1 pinout, TLE8250GXUMA1 application, or TLE8250GXUMA1 equivalent, key selection criteria include fail-safe operation modes (Normal/Receive-Only/Standby/Power Down), ESD robustness (>8 kV HBM), short-circuit protection to battery/GND/VCC, and RoHS-compliant PG-DSO-8 packaging for automotive-grade reliability.
Technical Context
The TLE8250GXUMA1 implements a fully differential HS CAN driver/receiver pair using Infineon's Smart Power Technology (SPT), integrating bipolar, CMOS, and DMOS on a single die to achieve high EMI immunity and low EME emission. Its symmetrical CANH/CANL slew rate control ensures stable signal integrity across 1 MBit/s operation.
It supports three functional states via NEN and NRM pins: Normal (full TX/RX), Receive-Only (TX disabled, RX active), and Standby/Power Down (ultra-low quiescent current). Internal pull-ups on NEN and NRM enable default Standby on power-up, while TxD time-out prevents bus lockup during controller faults.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 1 MBit/s - enables real-time communication in safety-critical ECUs without timing bottlenecks. |
| Common-Mode Range | ±40 V - ensures reliable operation under severe automotive load-dump and coupling noise conditions. |
| Bus Leakage (Power Down) | <1 µA - permits partial network wake-up without disturbing bus arbitration or voltage levels. |
| ESD Robustness | ±8 kV HBM - eliminates need for external TVS diodes in most board-level ESD protection schemes. |
| Supply Voltage Range | 4.5 V to 28 V - accommodates cold-crank (4.5 V) and load-dump (28 V) transients without reset or latch-up. |
| Differential Threshold | VDIFF ≥ 1.5 V dominant / ≤ 0.5 V recessive - guarantees interoperability with all ISO 11898-2-compliant nodes. |
| Thermal Shutdown | Trigger at 170 °C - protects against thermal runaway during sustained short-circuit events on CANH/CANL. |
Pinout & Package
Package: PG-DSO-8 (RoHS-compliant, exposed pad, 150 °C max junction temperature).
| 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, CANH, CANL, and logic circuits; requires low-inductance PCB connection. |
| 3 VCC | Supply Voltage Input | 4.5–28 V supply; mandates 100 nF ceramic decoupling capacitor placed within 5 mm of pin. |
| 4 RxD | Receive Data Output | CMOS-level output to CAN controller; "Low" during dominant bit; open-drain capable with external pull-up. |
| 5 NRM | Receive-Only Mode Control | Active-Low input; when pulled low, disables transmitter while preserving receiver functionality. |
| 6 CANL | CAN Bus Low I/O | Differential bus terminal; bidirectional; internally biased to VCC/2 in recessive state. |
| 7 CANH | CAN Bus High I/O | Differential bus terminal; bidirectional; complements CANL to generate 2 V nominal differential swing. |
| 8 NEN | Not Enable Input | Active-Low mode enable; "Low" activates Normal or Receive-Only mode; internal pull-up defaults to Standby. |
Key Features
| Feature | Design Value |
|---|---|
| Fail-Safe TxD Time-Out | Auto-disables transmitter after ~200 µs of continuous dominant TxD - prevents bus lockup during MCU hang. |
| Short-Circuit Protection | Withstands CANH/CANL shorted to battery, GND, or VCC indefinitely - no latch-up or damage below 170 °C. |
| Power Down Passive Behavior | Input impedance >100 MΩ on CANH/CANL - enables mixed-supply networks where unpowered nodes remain invisible. |
| EMI/EME Optimized Slew Rate | Controlled edge rates reduce radiated emissions by >10 dBµV/m vs. legacy transceivers at 100–500 MHz. |
| AEC-Q100 Qualified | Grade 1 (−40 °C to +125 °C ambient) - validated for engine bay deployment with 15-year lifetime reliability. |
Applications
| Engine Control Unit (ECU) | Electric Power Steering (EPS) |
|---|---|
Use Scenario: Real-time torque and position feedback loop between EPS motor controller and main ECU over CAN FD-ready infrastructure. IC Role / Device Role / Timing Role: Physical layer transceiver enabling deterministic 500 kBit/s command/response exchange with sub-100 µs latency. Use Value: Integrated short-circuit protection prevents system shutdown during motor phase-to-phase fault propagation onto CAN bus. |
Use Scenario: Safety-critical steering angle and assist-torque reporting from EPS sensor cluster to ADAS domain controller. IC Role / Device Role / Timing Role: Fault-tolerant HS CAN interface supporting ASIL-B decomposition via dual-redundant bus paths. Use Value: Power Down mode allows EPS module to enter ultra-low-power sleep while maintaining bus visibility for wake-on-CAN. |
| Chassis Control Module | Transmission Control Unit (TCU) |
Use Scenario: Coordinated brake-by-wire and suspension damping commands synchronized across distributed chassis nodes. IC Role / Device Role / Timing Role: Electromagnetic-immune transceiver ensuring error-free arbitration in high-noise 24 V chassis harnesses. Use Value: ±40 V common-mode range rejects coupled noise from solenoid drivers and PWM inverters near CAN routing. |
Use Scenario: Gearshift strategy updates and clutch pressure telemetry exchanged between TCU and engine ECU during launch control. IC Role / Device Role / Timing Role: High-symmetry CANH/CANL driver minimizing inter-symbol interference at 1 MBit/s burst transmission. Use Value: Low EME emission avoids RF interference with nearby AM/FM antenna systems and infotainment receivers. |
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 |
|---|---|---|---|
| TJA1042T/3 | Lower VCC range (4.5–27 V); no NRM pin; fixed 5 V VIO support only. | Lacks Receive-Only mode - unsuitable for partial-network monitoring architectures. | Select when board space is constrained and full TX/RX operation suffices; verify VCC transient margin. |
| SN65HVD251DR | Non-AEC-Q100; 3.3 V only; no thermal shutdown; ±25 V common-mode range. | Not qualified for under-hood use; limited to cabin or non-safety modules. | Choose only for cost-sensitive non-automotive industrial CAN nodes with stable 3.3 V supply. |
Compared with TJA1042T/3 and SN65HVD251DR, the TLE8250GXUMA1 uniquely combines AEC-Q100 Grade 1 qualification, 28 V supply tolerance, Receive-Only mode, and 170 °C thermal shutdown - making it the sole choice for ASIL-B-compliant powertrain and chassis networks requiring fail-operational behavior.

FAQ
Is TLE8250GXUMA1 pin-compatible with TLE6250G?
Yes - TLE8250GXUMA1 is fully pin- and function-compatible with TLE6250G. Pin 5 (RM → NRM) and Pin 8 (INH → NEN) retain identical electrical behavior despite naming changes; no PCB redesign is required for drop-in replacement in existing layouts.
What is the minimum VCC required for reliable CANH/CANL differential output?
The TLE8250GXUMA1 maintains guaranteed differential output swing (≥1.5 V) down to VCC = 4.5 V, validated per ISO 11898-2 under cold-crank conditions. Below 4.5 V, transmitter disable and undervoltage lockout activate to prevent undefined bus states.
How does the TxD time-out function behave during microcontroller reset?
When TxD remains continuously low for ~200 µs, the internal timer forces transmitter disable and holds CANH/CANL in recessive state. The timeout resets automatically upon TxD transition to high, allowing immediate resumption of normal operation without external intervention.
Can TLE8250GXUMA1 operate in a split-rail CAN network with 5 V and 3.3 V nodes?
Yes - its wide common-mode range (±40 V), bus-leakage-limited Power Down mode (<1 µA), and VCC-independent receiver thresholds allow interoperability across mixed-supply networks. No level-shifting circuitry is needed between 3.3 V and 5 V CAN controllers.
