Product details
Overview
TLE8250GXUMA5 from Infineon is a high-speed CAN transceiver compliant with ISO 11898-2, serving as the physical layer interface between CAN controllers and differential bus lines. It supports data rates up to 1 MBit/s, features TxD time-out, over-temperature protection, and short-circuit robustness to ground/battery/VCC, and operates across an extended VCC range (4.5–27 V) in automotive ECUs and chassis modules.
For engineers reviewing the TLE8250GXUMA5 datasheet, TLE8250GXUMA5 pinout, TLE8250GXUMA5 application, or TLE8250GXUMA5 equivalent, key selection criteria include fail-safe operation modes (Normal/Receive-Only/Power Down), ESD robustness (>±8 kV HBM), low bus leakage (<1 µA in Power Down), and AEC-Q100 qualification for under-hood deployment.
Technical Context
The TLE8250GXUMA5 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 for high EMI immunity and low EME. Its symmetrical CANH/CANL slew rate control ensures <1.5 dBµV/m radiated emission at 100 MHz per CISPR 25 Class 5.
Three configurable operation modes-Normal (full TX/RX), Receive-Only (TX disabled, RX active), and Power Down (high-impedance bus, <1 µA ICC)-are selected via NEN and NRM logic inputs. The device includes integrated undervoltage detection, thermal shutdown, and dominant timeout to prevent bus lock-up during controller faults.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 1 MBit/s - enables real-time communication in engine control and EPS systems. |
| VCC Range | 4.5 V to 27 V - supports cold-crank (4.5 V) and load-dump (27 V) conditions without external regulators. |
| Bus Leakage (Power Down) | <1 µA - prevents bus disturbance in partially powered networks with mixed supply domains. |
| ESD Robustness | ±8 kV HBM - eliminates need for external TVS diodes in standard automotive harness environments. |
| Common-Mode Range | −27 V to +40 V - ensures reliable operation despite ground offset in chassis-mounted nodes. |
| Thermal Shutdown | Trigger at 175 °C - protects against latch-up during sustained overcurrent or ambient overheating. |
| Fail-Safe TxD Timeout | Typ. 1.2 ms - forces recessive state if TxD remains dominant, preventing bus arbitration failure. |
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" = Dominant bus state. |
| 2 GND | Ground Reference | Primary return path for VCC, CANH, CANL, and logic signals; connects to exposed thermal pad. |
| 3 VCC | Supply Voltage | 4.5–27 V input; requires 100 nF decoupling capacitor to GND for noise suppression. |
| 4 RxD | Receive Data Output | CMOS-level output to CAN controller; "Low" during Dominant bus state; open-drain compatible. |
| 5 NRM | Receive-Only Mode Control | Active-Low input; pulls low to disable transmitter while retaining receiver functionality. |
| 6 CANL | CAN Bus Low I/O | Differential bus terminal; sinks current during Dominant state; high-impedance in Power Down. |
| 7 CANH | CAN Bus High I/O | Differential bus terminal; sources current during Dominant state; high-impedance in Power Down. |
| 8 NEN | Not Enable Input | Active-Low mode enable; low = Normal or Receive-Only mode; high = Standby/Power Down. |
Key Features
| Feature | Design Value |
|---|---|
| ISO 11898-2 Compliance | Fully compliant - meets differential voltage thresholds (VDIFF ≥1.5 V dominant, ≤0.5 V recessive) and timing jitter limits. |
| Power Down Bus Isolation | Input resistance >100 MΩ on CANH/CANL - enables plug-and-play node addition in live networks. |
| Short-Circuit Protection | Self-resetting protection against CANH/CANL short to GND, battery, or VCC - no latch-up or damage. |
| EMI/EME Performance | Passes CISPR 25 Class 5 radiated emission and ISO 11452-4 bulk current injection tests without ferrites. |
| AEC-Q100 Grade 1 | Qualified from −40 °C to +125 °C ambient - validated for engine bay and transmission control locations. |
Applications
| Engine Control Unit (ECU) | Electric Power Steering (EPS) |
|---|---|
Use Scenario: Real-time torque and position feedback between steering motor and ECU under vibration and temperature cycling. IC Role / Device Role / Timing Role: Physical layer transceiver handling bidirectional 500 kBit/s CAN FD–compatible frames with sub-µs propagation delay. Use Value: Low EME ensures no interference with adjacent radar sensors; short-circuit proofing prevents bus collapse during motor phase fault events. |
Use Scenario: Closed-loop assist control between EPS ECU and torque sensor, requiring deterministic latency and fault resilience. IC Role / Device Role / Timing Role: HS CAN interface with fail-safe TxD timeout and Receive-Only mode for diagnostic monitoring during controller reset. Use Value: Power Down mode isolates inactive nodes without bus termination loss; ±8 kV ESD withstands assembly-handling discharge events. |
| Chassis Control Module | Transmission Control Unit (TCU) |
Use Scenario: Coordination of ABS, ESC, and air suspension actuators across distributed nodes on shared CAN backbone. IC Role / Device Role / Timing Role: Differential bus driver/receiver supporting multi-master arbitration and dominant bit monitoring. Use Value: Wide common-mode range (−27 V to +40 V) accommodates ground potential shifts between body and chassis grounds. |
Use Scenario: Gear shift command transmission and clutch pressure feedback in automatic transmissions under high EMI from solenoid drivers. IC Role / Device Role / Timing Role: Robust physical layer interface with thermal shutdown and undervoltage lockout for load-dump survival. Use Value: Extended VCC range (4.5–27 V) eliminates need for external LDO; green RoHS packaging meets Tier-1 sustainability requirements. |
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 min (4.5 V same), but lacks TxD time-out and has higher bus leakage (5 µA vs. <1 µA) in sleep mode. | Less suitable for mixed-supply CAN networks requiring ultra-low leakage isolation. | Select when cost sensitivity outweighs partial-network robustness requirements. |
| SN65HVD251DR | Non-AEC qualified, narrower VCC range (4.5–12 V), no overtemperature protection or short-circuit recovery. | Restricted to non-automotive industrial CAN nodes with stable 5 V/12 V supplies and benign thermal environments. | Use only in non-safety-critical, non-automotive designs where AEC-Q100 is not mandated. |
Compared with TJA1042T/3 and SN65HVD251DR, the TLE8250GXUMA5 delivers superior fail-safe behavior-including dominant timeout, thermal shutdown, and <1 µA Power Down leakage-making it uniquely suited for AEC-Q100-compliant automotive domains where bus integrity must be maintained across power domain boundaries and fault conditions.

FAQ
Is TLE8250GXUMA5 pin-compatible with TLE6250G?
Yes - TLE8250GXUMA5 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 purpose of the NRM pin?
The NRM (Receive-Only Mode) pin is an active-low control input that disables the transmitter while keeping the receiver active. When pulled low, it allows the node to monitor bus traffic without transmitting, enabling diagnostic listening or safe operation during controller initialization or fault recovery.
Does TLE8250GXUMA5 support wake-up from Power Down mode?
No - TLE8250GXUMA5 is a high-speed CAN transceiver defined by ISO 11898-2 and does not include a dedicated wake-up function. Wake-up capability requires ISO 11898-5–compliant transceivers such as TLE9250VSJ or TCAN1042HV-Q1.
How does the TxD time-out function improve system reliability?
The TxD time-out circuit monitors TxD input duration and forces RxD to recessive after ~1.2 ms if TxD remains dominant. This prevents bus lock-up caused by microcontroller hangs or firmware errors, ensuring other nodes retain arbitration access and maintaining network-level fault containment.
