Product details

Overview

TLE7250GXUMA1 from Infineon Technologies is a high-speed CAN transceiver for automotive and industrial networks, compliant with ISO 11898-2, supporting up to 1 Mbps data rate, operating from 4.5 V to 5.5 V supply, featuring integrated overtemperature and short-circuit protection, and used as the physical-layer interface between CAN controllers and differential bus lines in ECU designs.

For engineers reviewing the TLE7250GXUMA1 datasheet, TLE7250GXUMA1 pinout, TLE7250GXUMA1 application, or TLE7250GXUMA1 equivalent, key selection criteria include bus fault tolerance (CANH/CANL short-circuit proof to ground, battery, and VCC), power-down state leakage (<1 µA), mode control via NEN/NRM pins, and AEC-Q100 qualification for under-hood deployment.

Technical Context

The TLE7250GXUMA1 implements a fully differential HS-CAN physical layer with symmetrical CANH/CANL slew-rate control to minimize electromagnetic emission (EME) across 1–100 MHz. Its receiver detects dominant states at V_DIFF ≥ 1.5 V and recessive states at V_DIFF ≤ 0.5 V per ISO 11898-2.

It supports three operational modes-normal (transmit + receive), receive-only, and stand-by-selected via dual logic inputs (NEN, NRM) with internal pull-ups. In power-down, input resistance exceeds 1 MΩ and bus leakage drops below 1 µA, enabling robust operation in partially-supplied CAN networks.

Key Specifications

Parameter	Value and Actual Design Meaning
Data Rate	Up to 1 Mbps - enables real-time communication in powertrain and chassis ECUs.
Supply Voltage	4.5 V to 5.5 V - accommodates automotive battery variations including cold-crank conditions.
Common-Mode Range	−2 V to 14 V - ensures immunity against load-dump and jump-start transients.
Bus Leakage (Power-down)	<1 µA - prevents bus disturbance when node is unpowered in mixed-supply networks.
ESD Immunity	±8 kV HBM - meets IEC 61000-4-2 Level 4 for robustness in assembly and field environments.
Thermal Protection	Activation at T_j > 160 °C - shuts down output stage to prevent latch-up during overheating.
Fail-Safe Features	TxD time-out, undervoltage lockout, unconnected pin detection - eliminates undefined bus behavior during controller faults.

Pinout & Package

Package: PG-DSO-8 (RoHS-compliant, surface-mount, 8-pin SOIC variant with exposed thermal pad).

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 and bus drivers; must be low-inductance connection to minimize EMI.
3 VCC	Supply Voltage	4.5–5.5 V transceiver supply; requires 100 nF decoupling capacitor to GND at pin.
4 RxD	Receive Data Output	CMOS-level output to CAN controller; "low" during dominant bus state.
5 NRM	Not Receive-only Mode Input	Active-low control; "low" enables receive-only mode; internal pull-up to VCC.
6 CANL	CAN Bus Low I/O	Differential bus terminal; sinks current in dominant state; short-circuit protected to GND/VCC/battery.
7 CANH	CAN Bus High I/O	Differential bus terminal; sources current in dominant state; symmetric slew rate with CANL.
8 NEN	Not Enable Input	Active-low mode enable; "low" activates normal or receive-only mode; internal pull-up to VCC.

Key Features

Feature	Design Value
ISO 11898-2 Compliance	Fully compliant - guarantees interoperability with all standard HS-CAN nodes without protocol translation.
Partially-Supplied Network Support	High-impedance power-down state - allows live bus operation while individual nodes are unpowered.
Integrated Fail-Safe Logic	TxD time-out + undervoltage lockout + open-pin detection - prevents bus lockup during MCU reset or brownout.
Low EME/High EMI Immunity	Optimized driver symmetry + wide common-mode range - reduces radiated emissions and improves noise rejection in dense ECU layouts.
AEC-Q100 Qualified	Grade 1 (−40 °C to +125 °C ambient) - validated for engine bay, transmission, and ADAS module placement.

Applications

Use Scenario: Sensor fusion data (radar, camera, ultrasonic) aggregated across distributed ADAS ECUs via CAN FD backbone.

IC Role / Device Role / Timing Role: HS-CAN interface ensuring bit-accurate reception of time-critical object detection packets with <500 ns jitter.

Use Value: Maintains bus integrity during ESD events near windshield-mounted sensors and resists conducted noise from DC-DC converters.

Body Control Module

Electric Power Steering

Use Scenario: Centralized lighting, door lock, and climate control coordination across multiple body domain ECUs.

IC Role / Device Role / Timing Role: Robust bus node with receive-only mode for diagnostic monitoring without bus arbitration conflict.

Use Value: Reduces quiescent current to <10 µA in sleep mode while retaining wake-on-CAN capability via external logic.

Use Scenario: Torque feedback loop between steering angle sensor, motor driver, and main EPS controller.

IC Role / Device Role / Timing Role: Fault-tolerant transceiver with short-circuit protection on CANH/CANL to survive motor winding faults.

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	Includes wake-up capability via WAKE pin; slightly higher V_IO tolerance (5.5 V); no NRM pin - receive-only mode not supported.	Required where local wake-up from sleep is needed; unsuitable for partial-network receive-only monitoring.	Select if wake-up functionality is mandatory and receive-only mode is unnecessary.
SN65HVD230DR	Non-AEC qualified; lower ESD rating (±4 kV); no overtemperature shutdown; wider supply range (3–5.5 V).	Limited to non-automotive industrial use; cannot be deployed in under-hood or safety-critical systems.	Select only for cost-sensitive, non-automotive CAN nodes with no thermal or transient stress requirements.

Compared with TJA1042T/3 and SN65HVD230DR, the TLE7250GXUMA1 uniquely combines AEC-Q100 Grade 1 qualification, receive-only mode control (NRM), and sub-1 µA power-down leakage-making it optimal for mixed-supply automotive domains requiring fail-safe bus monitoring without wake-up overhead.

FAQ

Is TLE7250GXUMA1 pin-compatible with TLE6250G?

Yes, TLE7250GXUMA1 is functionally and pin-compatible with TLE6250G, though pin 5 (RM → NRM) and pin 8 (INH → NEN) have renamed symbols. The electrical functions and layout remain identical, enabling drop-in replacement in existing designs without PCB revision.

What is the maximum allowable bus capacitance for reliable 1 Mbps operation?

The TLE7250GXUMA1 supports 1 Mbps operation with total bus capacitance up to 44 pF per node, as verified in Infineon's application note AN2012-07. Exceeding this value increases rise/fall time asymmetry and may cause bit errors in long stub configurations.

Does TLE7250GXUMA1 support CAN FD physical layer?

No, TLE7250GXUMA1 is strictly compliant with ISO 11898-2 for classical HS-CAN (up to 1 Mbps). It does not support the higher data rates, variable bit timing, or improved error detection of CAN FD, which requires ISO 11898-2:2016-compliant transceivers like TJA1044.

How is the TxD time-out function implemented and what is its timeout duration?

The TxD time-out function disables the transmitter after detecting >5 dominant bits without a recessive transition, preventing bus lockup during controller faults. Timeout duration is fixed at approximately 20 µs (equivalent to five bit times at 1 Mbps), and recovery occurs automatically upon next recessive TxD edge.
