Product details

Overview

TLE7250SJXUMA1 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 guaranteed loop delay symmetry, operates across 4.5 V to 5.5 V VCC supply, and delivers ESD robustness per IEC61000-4-2 (±8 kV contact). It is deployed in engine control units for real-time sensor/actuator communication.

For engineers reviewing the TLE7250SJXUMA1 datasheet, TLE7250SJXUMA1 pinout, TLE7250SJXUMA1 application, or TLE7250SJXUMA1 equivalent, key selection criteria include bus fault tolerance (short-circuit proof to ground/battery/VCC), low-power modes (power-save and receive-only), thermal protection, and AEC-Q100 qualification for automotive deployment.

Technical Context

The TLE7250SJXUMA1 implements a differential driver/receiver pair with symmetrical slew-rate control on CANH and CANL to minimize electromagnetic emission (EME) and maximize immunity. Its internal mode controller manages three states-normal, power-save, and receive-only-via NEN and NRM pins, with automatic fail-safe behavior during undervoltage or overtemperature events.

It integrates short-circuit protection on both bus lines, TxD time-out functionality to prevent bus lock-up, and a precision receiver threshold referenced to VCC/2. The device uses Infineon's Smart Power Technology (SPT) for robust operation under automotive transients (ISO 7637-2) and maintains <1 µA leakage current on CANH/CANL in power-down state.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage (VCC)	4.5 V to 5.5 V - ensures compatibility with automotive 5 V rail under load dump and cold-crank conditions.
Data Rate	Up to 2 MBit/s - enables CAN FD frame transmission without signal integrity degradation.
Common-Mode Range	−2 V to 14 V - provides immunity against noise coupling in harsh vehicle environments.
ESD Robustness	±8 kV contact (IEC61000-4-2) - eliminates need for external TVS diodes in most layouts.
Bus Fault Protection	Short-circuit proof to GND, battery, and VCC - prevents latch-up or destruction during wiring faults.
Thermal Shutdown	Triggered at Tj > 175 °C - protects silicon during sustained overload or poor heatsinking.
Power-Down Leakage	<1 µA on CANH/CANL - preserves bus quiescence and avoids false wake-ups in sleep networks.

Pinout & Package

Package: PG-DSO-8 (lead-free, RoHS-compliant, halogen-free); thermally enhanced with exposed pad connected to PCB ground plane for heat dissipation.

Pin/Terminal	Circuit Role	Design Meaning
1 TxD	Transmit Data Input	CMOS-level input with internal pull-up to VCC; "low" asserts dominant bus state.
2 GND	Ground Reference	Primary return path for transmitter, receiver, and internal bias circuits; connects to exposed pad.
3 VCC	Transmitter Supply	5 V nominal supply requiring 100 nF decoupling capacitor to GND for stability.
4 RxD	Receive Data Output	CMOS-level output; "low" indicates dominant bus state, synchronized to internal receiver threshold.
5 NRM	Not Receive-Only Mode Control	Active-low enable for receive-only mode; "low" disables driver, isolating bus from node.
6 CANL	CAN Bus Low Terminal	Differential bus line with controlled slew rate; sinks current during dominant state.
7 CANH	CAN Bus High Terminal	Differential bus line with matched slew rate; sources current during dominant state.
8 NEN	Not Enable Input	Active-low master enable; "low" activates normal or receive-only mode, "high" forces power-down.

Key Features

Feature	Design Value
Loop Delay Symmetry	Guaranteed t_Loop(H,L) ≈ t_Loop(L,H) - ensures accurate bit timing for CAN FD at 2 MBit/s.
Fail-Safe TxD Time-Out	Auto-disables driver after 10 µs of continuous dominant TxD - prevents bus lock-up during MCU hang.
Mode Flexibility	Three hardware-configurable modes (normal, power-save, receive-only) - reduces system power by >90% in sleep states.
Automotive Transient Immunity	Withstands ISO 7637-2 Pulse 1, 2a, 3a/b - eliminates need for external protection in standard ECUs.
Passive Bus Behavior	<1 µA leakage on CANH/CANL in power-down - maintains network integrity without disturbing other nodes.

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
PCA82C251T/N,112	Lacks CAN FD support; max data rate 1 MBit/s; no TxD time-out or receive-only mode.	Suitable only for legacy CAN 2.0B networks; not qualified for CAN FD or AEC-Q100 Grade 1.	Select when cost sensitivity outweighs FD capability and automotive qualification requirements.
SN65HVD230DR	Non-AEC-Q100; lower ESD rating (±4 kV); no bus short-circuit protection to battery or VCC.	Intended for industrial/commercial CAN nodes; unsuitable for under-hood automotive use.	Choose only for non-automotive designs where ambient temperature stays below 105 °C and ESD risk is low.

Compared with PCA82C251T/N,112 and SN65HVD230DR, the TLE7250SJXUMA1 uniquely combines AEC-Q100 Grade 1 qualification, 2 MBit/s CAN FD readiness, integrated fail-safes (TxD timeout, overtemperature, bus fault protection), and automotive-grade transient immunity-making it the sole choice for new automotive ECU designs requiring functional safety compliance.

FAQ

What is the maximum operating junction temperature for TLE7250SJXUMA1?

The TLE7250SJXUMA1 has a specified maximum junction temperature of 175 °C, with integrated overtemperature protection that disables the driver and receiver above this threshold. Thermal resistance θ_JA is 60 K/W in standard JEDEC 2-layer board layout, and the exposed pad must be soldered to a minimum 100 mm² copper area for effective heat dissipation.

Does TLE7250SJXUMA1 support CAN FD, and what design features enable it?

Yes, the TLE7250SJXUMA1 supports CAN FD up to 2 MBit/s due to guaranteed loop delay symmetry between CANH and CANL paths, controlled slew rates minimizing signal ringing, and low propagation delay variation (<5 ns) across voltage and temperature. These features ensure accurate bit sampling at higher data rates without requiring external equalization.

How does the TxD time-out function operate, and can it be disabled?

The TxD time-out triggers automatically if the TxD input remains low for longer than 10 µs, forcing the driver into high-impedance state to prevent bus lock-up. This feature is hardwired and cannot be disabled-it is an intrinsic fail-safe mechanism independent of mode control pins or external configuration.

Is the exposed thermal pad on PG-DSO-8 package required to be grounded?

Yes, the exposed pad (Pin 9, labeled "PAD") must be soldered to a PCB ground plane and electrically connected only to GND. It serves as the primary thermal path and part of the signal reference; connecting it to any other potential-including VCC or floating-violates the device's thermal and EMI specifications and may cause malfunction or premature failure.
