Product details

Overview

TLE7250XLEXUMA1 from Infineon Technologies is a high-speed CAN transceiver compliant with ISO 11898-2, serving as the physical layer interface between CAN protocol controllers and automotive HS CAN buses. It supports data rates up to 2 MBit/s, features VIO voltage adaptation (2.5–5.5 V), operates across VCC = 4.5–27 V, and delivers ±8 kV ESD robustness per IEC 61000-4-2. It is deployed in body control modules, powertrain gateways, and chassis domain controllers requiring fault-tolerant, low-EMI communication.

For engineers reviewing the TLE7250XLEXUMA1 datasheet, TLE7250XLEXUMA1 pinout, TLE7250XLEXUMA1 application, or TLE7250XLEXUMA1 equivalent, key selection criteria include bus leakage current in power-down mode (≤1 µA), loop delay symmetry (<10 ns), short-circuit protection to battery/GND/VCC, receive-only mode enablement via RM pin, and AEC-Q100 qualification for automotive use.

Technical Context

The TLE7250XLEXUMA1 implements a differential driver/receiver pair with independent VCC (transmitter supply) and VIO (logic supply) rails, enabling mixed-voltage system integration. Its internal pull-up on TxD and pull-down on RM allow default-mode configuration without external biasing, while the CANH/CANL output stage uses optimized slew-rate control to meet ISO 11898-2 emission limits.

It supports three operational states: Normal mode (full transmit/receive), Receive-only mode (TxD disabled, bus activity monitored), and Power-down (low-leakage bus hold). Fail-safe functions include TxD time-out (prevents bus lock-up), overtemperature shutdown (>150 °C), and undervoltage detection on both VCC and VIO rails.

Key Specifications

Parameter	Value and Actual Design Meaning
Data Rate	Up to 2 MBit/s - enables CAN FD frame transmission with guaranteed loop delay symmetry ≤10 ns.
VCC Supply Range	4.5 V to 27 V - supports direct connection to automotive battery rail with transient tolerance.
VIO Supply Range	2.5 V to 5.5 V - adapts logic levels to MCU I/O voltage without level shifters.
Bus Leakage (Power-down)	≤1 µA - maintains bus integrity during sleep modes in always-on domains.
ESD Robustness	±8 kV HBM - meets IEC 61000-4-2 Level 4 for system-level surge immunity.
Common-Mode Range	−2 V to 14 V - ensures reliable operation under load-dump and jump-start conditions.
AEC-Q100 Grade	Grade 1 (−40 °C to +125 °C ambient) - qualified for engine bay and under-hood applications.

Pinout & Package

Package: PG-TSON-8 (leadless, thermally enhanced, AOI-compatible); 3.0 mm × 3.0 mm footprint, exposed thermal pad (connected to GND).

Pin/Terminal	Circuit Role	Design Meaning
1 TxD	Transmit Data Input	CMOS input with internal pull-up to VIO; "low" asserts dominant bus state.
2 GND	Ground Reference	Primary return path for VCC, VIO, and CAN bus; connects to thermal pad.
3 VCC	Transmitter Supply	High-side driver rail; requires 100 nF decoupling capacitor to GND.
4 RxD	Receive Data Output	CMOS output referenced to VIO; "low" indicates dominant bus state.
5 VIO	Digital Supply Input	Sets logic threshold and output swing; 100 nF decoupling required.
6 CANL	CAN Bus Low Terminal	Differential bus I/O; sinks current during dominant state.
7 CANH	CAN Bus High Terminal	Differential bus I/O; sources current during dominant state.
8 RM	Receive-only Mode Control	Active-low input with internal pull-down; "low" = normal mode, "high" = RX-only.

Key Features

Feature	Design Value
VIO voltage adaptation	Enables seamless interfacing with 2.5 V, 3.3 V, or 5 V MCUs without external level shifters.
Receive-only mode (RM pin)	Disables transmitter while preserving bus monitoring - critical for gateway nodes during firmware updates.
TxD time-out function	Automatically forces bus recessive after 1.2 ms of continuous dominant TxD, preventing network lock-up.
Short-circuit proof outputs	Withstands CANH/CANL shorted to GND, battery, or VCC indefinitely without latch-up or damage.
Low-power bus hold	≤1 µA leakage in power-down ensures minimal current draw in vehicle sleep states (e.g., S3/S4).

Applications

Body Control Module (BCM)

Powertrain Gateway

Use Scenario: Centralized control of lighting, door locks, and window lifts via HS CAN backbone.

IC Role / Device Role / Timing Role: Physical layer transceiver translating MCU UART/CAN controller signals to differential bus voltages.

Use Value: VIO adaptation allows direct connection to 3.3 V microcontrollers; low EME ensures compliance with OEM EMC test limits (e.g., CISPR 25 Class 3).

Use Scenario: Aggregating CAN messages between engine, transmission, and chassis ECUs.

IC Role / Device Role / Timing Role: High-integrity bus interface with fail-safe TxD timeout and short-circuit resilience.

Use Value: Loop delay symmetry <10 ns supports error-free CAN FD 2 MBit/s arbitration and data phases.

Chassis Domain Controller

ADAS Sensor Hub

Use Scenario: Real-time coordination of ABS, ESC, and airbag systems using time-triggered CAN frames.

IC Role / Device Role / Timing Role: Robust physical layer node with overtemperature shutdown and undervoltage lockout.

Use Value: AEC-Q100 Grade 1 rating and −2 V to 14 V common-mode range ensure operation during load-dump events.

Use Scenario: Consolidating radar, camera, and ultrasonic sensor data onto a centralized CAN FD backbone.

IC Role / Device Role / Timing Role: Low-leakage bus interface enabling extended sleep mode with wake-on-CAN capability.

Use Value: ≤1 µA bus leakage in power-down preserves battery life in parked ADAS systems (e.g., parking assist).

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 TJA1043T/3	Includes wake-up functionality (WAKE pin); slightly higher VCC quiescent current (80 µA vs. 60 µA).	Required where local wake-up from sleep via bus activity is needed; not drop-in compatible due to WAKE pin presence.	Select when system architecture mandates wake-on-CAN; verify RM pin mapping and timing for receive-only mode.
ST TJA1057G	No VIO pin - fixed 3.3 V logic interface; lacks TxD time-out and forced receive-only mode.	Suitable only for homogeneous 3.3 V systems; cannot replace TLE7250XLEXUMA1 in mixed-voltage or safety-critical gateways.	Choose only for cost-sensitive, single-rail designs without fail-safe requirements like TxD timeout or bus short-circuit proofing.

Compared with TJA1043T/3 and TJA1057G, the TLE7250XLEXUMA1 uniquely combines VIO adaptability, TxD time-out, and dual-package AOI support - making it optimal for scalable automotive platforms requiring design reuse across voltage domains and functional safety layers.

FAQ

What is the purpose of the RM pin on the TLE7250XLEXUMA1?

The RM (Receive-only Mode) pin is an active-high control input that disables the transmitter while keeping the receiver active. When pulled high, it places the device in receive-only mode - essential for gateway nodes that must monitor bus traffic without transmitting during firmware updates or diagnostic sessions. Internal pull-down ensures default normal operation if left unconnected.

Does the TLE7250XLEXUMA1 support CAN FD?

Yes - the TLE7250XLEXUMA1 supports CAN FD physical layer signaling up to 2 MBit/s. Its guaranteed loop delay symmetry (<10 ns) and controlled slew rates meet ISO 11898-2 requirements for error-free FD arbitration and data phase transitions. It does not implement CAN FD protocol logic; that resides in the connected MCU's CAN controller.

How is thermal management handled in the PG-TSON-8 package?

The PG-TSON-8 package features an exposed thermal pad on the bottom surface, which must be soldered to a PCB copper pour connected to GND. This pad provides the primary thermal conduction path, reducing junction-to-board thermal resistance to 35 K/W. No heatsink is required for typical automotive ambient conditions up to +125 °C.

Can VIO and VCC be powered from the same supply rail?

Yes - VIO and VCC may share a common 5 V supply, but only if the MCU and transceiver logic both operate at 5 V. Doing so forfeits VIO's voltage adaptation benefit. For 3.3 V MCUs, VIO must be supplied separately at 3.3 V to ensure correct logic thresholds and output swing; VCC remains independent at 12 V or 24 V.
