Product details
Overview
TLE6251DXUMA2 from Infineon is a high-speed CAN transceiver compliant with ISO 11898-2/-5, serving as the physical-layer interface between a CAN controller and differential bus lines. It supports up to 1 Mbps data rate, features bus wake-up via RxD signal change, operates across extended VCC (4.5–27 V) and VIO (3.0–5.5 V) supply ranges, and delivers <10 µA quiescent current in stand-by mode. It is used in automotive gateway modules requiring robust ESD immunity (±8 kV HBM), low EME, and fail-safe short-circuit protection.
For engineers reviewing the TLE6251DXUMA2 datasheet, TLE6251DXUMA2 pinout, TLE6251DXUMA2 application, or TLE6251DXUMA2 equivalent, key selection criteria include ISO 11898-2 compliance, VIO-adaptive logic levels, remote wake-up capability, CANH/CANL bus fault tolerance, and AEC-Q100 qualification for automotive deployment.
Technical Context
The TLE6251DXUMA2 implements a dual-mode architecture: normal operation enables full-duplex HS-CAN communication with dominant/recessive state encoding via differential VDIFF = VCANH – VCANL ≥1.5 V (dominant) or ≤0.5 V (recessive); stand-by mode disables VCC while retaining VIO-powered wake-up detection on RxD output.
Its Smart Power Technology (SPT) enables integrated overtemperature protection, undervoltage detection, TxD time-out function, and CAN bus short-circuit resilience to ground, battery, and VCC. The receiver input is disabled in power-down state, yielding <1 µA bus leakage current and high-impedance passive behavior on CANH/CANL.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 1 Mbps - supports real-time control in high-bandwidth automotive networks like powertrain and ADAS. |
| Supply Range (VCC) | 4.5 V to 27 V - accommodates wide automotive battery fluctuations including load dump and cold-crank conditions. |
| Digital Supply (VIO) | 3.0 V to 5.5 V - adapts logic I/O levels to match 3.3 V or 5 V microcontrollers without level-shifting circuitry. |
| Stand-by Current | <10 µA - enables ultra-low-power node wake-up in always-on gateway or body control modules. |
| ESD Immunity | ±8 kV HBM - ensures robustness against human-body model electrostatic discharge in assembly and service environments. |
| Common-Mode Range | −27 V to +40 V - guarantees reliable operation under severe electromagnetic interference (EMI) in vehicle harnesses. |
| Bus Leakage (Power-down) | <1 µA - prevents parasitic loading of CAN bus in partially-supplied networks with mixed power states. |
Pinout & Package
Package: PG-DSO-8 (RoHS-compliant, surface-mount, 8-pin exposed pad SOIC variant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 TxD | Transmit Data Input | CMOS-compatible serial input from CAN controller; internal pull-up to VIO; "low" asserts dominant bus state. |
| 2 GND | Ground Reference | Primary return path for VCC, VIO, and CAN driver circuits; requires low-inductance PCB layout. |
| 3 VCC | Transceiver Power Supply | High-voltage supply (4.5–27 V); decoupled with 100 nF capacitor; can be switched off in stand-by mode. |
| 4 RxD | Receive Data Output | CMOS output to CAN controller; "low" during dominant bus state; used for wake-up detection in stand-by. |
| 5 VIO | Digital I/O Supply | Sets logic voltage thresholds for TxD, RxD, and STB; enables interoperability with 3.3 V or 5 V MCUs. |
| 6 CANL | CAN Bus Low Terminal | Differential bus I/O; sinks current in dominant state; short-circuit protected to ground, battery, and VCC. |
| 7 CANH | CAN Bus High Terminal | Differential bus I/O; sources current in dominant state; symmetric slew rate minimizes EME. |
| 8 STB | Stand-by Control Input | Active-low mode selector; internal pull-up to VIO; "low" enables normal operation; "high" enters stand-by. |
Key Features
| Feature | Design Value |
|---|---|
| ISO 11898-2/-5 Compliance | Fully meets physical layer requirements for high-speed CAN, including differential voltage thresholds and timing jitter limits. |
| Remote Wake-up via RxD | Enables wake-up event generation without external interrupt lines-RxD state change triggers MCU wake-up in stand-by. |
| VIO-Adaptive Logic Levels | Eliminates need for external level shifters when interfacing with mixed-voltage microcontrollers (3.3 V or 5 V I/O). |
| Fail-Safe TxD Time-out | Prevents bus lock-up by forcing recessive state if TxD remains dominant >1.2 ms-critical for arbitration integrity. |
| Automotive Transient Protection | Withstands ISO 7637-2 pulse 1, 2a, 3a/b and load-dump pulses up to ±40 V without external clamping. |
Applications

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 |
|---|---|---|---|
| NXP TJA1042T/3 | Lower VCC min (4.5 V same), but no VIO pin-logic levels fixed to VCC; lacks RxD-based wake-up (uses dedicated WAKE pin). | Requires external level-shifter for 3.3 V MCUs; wake-up routing needs additional GPIO. | Preferred where board space is constrained and VIO flexibility is unnecessary. |
| ST TJA1057 | Higher max data rate (5 Mbps), but only AEC-Q100 Grade 2 (−40°C to +105°C vs. Grade 0: −40°C to +150°C for TLE6251DXUMA2). | Not qualified for under-hood applications above 125°C ambient (e.g., engine bay gateways). | Select when ultra-high speed is required and temperature grade is secondary. |
Compared with TJA1042T/3 and TJA1057, the TLE6251DXUMA2 uniquely combines VIO adaptability, RxD-triggered wake-up, and AEC-Q100 Grade 0 qualification-making it optimal for thermally demanding, mixed-voltage automotive nodes requiring minimal external components.

FAQ
What is the maximum CAN bus data rate supported by the TLE6251DXUMA2?
The TLE6251DXUMA2 supports data rates up to 1 Mbps, fully compliant with ISO 11898-2 timing requirements for high-speed CAN. Its optimized slew rate control ensures signal integrity and low electromagnetic emission (EME) at this rate, making it suitable for real-time powertrain and ADAS communication.
How does the TLE6251DXUMA2 achieve wake-up from stand-by mode?
Wake-up is triggered by a signal transition on the RxD pin-no dedicated wake pin is required. When the device is in stand-by (STB = high), the low-power receiver monitors bus activity and asserts a logic change on RxD, signaling the connected microcontroller to exit sleep mode. This eliminates extra GPIO usage and simplifies PCB routing.
Can the TLE6251DXUMA2 interface directly with a 3.3 V microcontroller?
Yes. The VIO pin accepts 3.0–5.5 V, setting logic thresholds for TxD, RxD, and STB. When VIO = 3.3 V, all digital I/Os operate at 3.3 V CMOS levels-enabling direct connection to 3.3 V MCUs without level shifters or resistive dividers.
Is the TLE6251DXUMA2 qualified for under-hood automotive use?
Yes. It is AEC-Q100 qualified (Grade 0: −40°C to +150°C ambient), features integrated overtemperature protection, and withstands automotive transients per ISO 7637-2. Its PG-DSO-8 package with exposed thermal pad supports reliable thermal dissipation in high-temperature engine compartment deployments.
