Product details

Overview

TLE8250GVIOXUMA5 from Infineon is a high-speed CAN transceiver for automotive networks, serving as the physical layer interface between CAN protocol controllers and the differential bus. It supports up to 1 MBit/s data rate, operates across extended VCC (4.5–27 V) and VIO (3.0–5.5 V) supply ranges, features TxD time-out and over-temperature protection, and is deployed in engine control units requiring robust EMI immunity and AEC-Q100 qualification.

For engineers reviewing the TLE8250GVIOXUMA5 datasheet, TLE8250GVIOXUMA5 pinout, TLE8250GVIOXUMA5 application, or TLE8250GVIOXUMA5 equivalent, key selection criteria include ISO 11898-2 compliance, dual-supply voltage adaptation (VIO), fail-safe operation modes (Normal/Stand-By/Power Down), and CANH/CANL slew-rate control for EME reduction in mixed-supply networks.

Technical Context

The TLE8250GVIOXUMA5 implements a fully differential HS-CAN physical layer compliant with ISO 11898-2, using matched driver stages on CANH and CANL to maintain signal symmetry and 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, with internal bus biasing at V_CC/2 in Normal mode.

It supports three operational states controlled by the NEN pin: Normal Operation (NEN = Low, full TX/RX active), Stand-By (NEN = High, driver/receiver disabled, high-impedance bus), and Power Down (triggered by V_CC or V_IO undervoltage, with <1 µA bus leakage). Fail-safe features include TxD time-out, CAN short-circuit protection to ground/battery/V_CC, and thermal shutdown.

Key Specifications

Parameter	Value and Actual Design Meaning
Data Rate	Up to 1 MBit/s - enables real-time communication in powertrain ECUs without timing bottlenecks.
VCC Supply Range	4.5 V to 27 V - accommodates automotive battery transients and cold-crank conditions down to 4.5 V.
VIO Supply Range	3.0 V to 5.5 V - allows direct interfacing with both 3.3 V and 5 V microcontrollers without level shifters.
Common-Mode Range	−27 V to +40 V - ensures reliable operation during load-dump and reverse-battery events per ISO 7637-2.
Bus Leakage (Power Down)	< 1 µA - prevents bus disturbance in partially powered CAN networks, preserving arbitration integrity.
ESD Robustness	±8 kV HBM - eliminates need for external TVS diodes in most board-level ESD stress scenarios.
Thermal Shutdown	Triggered at T_j ≥ 175 °C - protects against latch-up and permanent damage during sustained overload.

Pinout & Package

Supplied in a RoHS-compliant PG-DSO-8 (SOIC-8) package with exposed thermal pad, the TLE8250GVIOXUMA5 uses surface-mount assembly and supports automated optical inspection (AOI) via visible marking "8250GVIO".

Pin/Terminal	Circuit Role	Design Meaning
1 TxD	Transmit Data Input	CMOS-compatible input with internal pull-up to VIO; "Low" asserts dominant bus state.
2 GND	Ground Reference	Analog/digital common return for VCC, VIO, and bus drivers; requires low-inductance PCB connection.
3 VCC	Transceiver Supply	Main power rail (4.5–27 V); requires 100 nF decoupling capacitor to GND near pin.
4 RxD	Receive Data Output	CMOS output referenced to VIO; "Low" indicates dominant bus state, compatible with MCU I/O thresholds.
5 VIO	Digital I/O Supply	Sets logic levels for TxD, RxD, and NEN; decoupled with 100 nF capacitor to GND.
6 CANL	CAN Bus Low	Differential bus terminal; sinks current during dominant state; must be routed with matched length to CANH.
7 CANH	CAN Bus High	Differential bus terminal; sources current during dominant state; forms 60 Ω differential impedance with CANL.
8 NEN	Not Enable Input	Active-Low mode control: Low = Normal Operation, High = Stand-By; internal VIO pull-up.

Key Features

Feature	Design Value
VIO-adapted I/O logic	Enables seamless integration with 3.3 V or 5 V MCUs without external level translation circuitry.
Optimized slew-rate control	Reduces electromagnetic emission (EME) across 30–100 MHz band while maintaining 1 MBit/s timing margins.
Fail-safe TxD time-out	Automatically disables driver after 250 µs of continuous dominant TxD, preventing bus lockup during MCU faults.
Partial-network compatibility	Power Down mode presents >1 MΩ bus impedance, allowing live nodes to communicate even when others are unpowered.
AEC-Q100 Grade 1 qualified	Rated for −40 °C to +125 °C ambient operation, validated for 1500-hr HTOL and 1000-cycle temperature cycling.

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 range (4.5–28 V vs. 4.5–27 V); no VIO pin - fixed 5 V logic interface only.	Lacks VIO adaptability; unsuitable for mixed-voltage designs with 3.3 V MCUs.	Select when legacy 5 V-only architecture simplifies BOM and layout.
SN65HVD230DR	Non-AEC-Q100; max 1 MBit/s but no thermal shutdown or bus short-circuit protection to battery.	Not qualified for automotive powertrain; limited to industrial or infotainment subsystems.	Select only for cost-sensitive non-safety-critical applications outside AEC scope.

Compared with TJA1042T/3 and SN65HVD230DR, the TLE8250GVIOXUMA5 uniquely combines AEC-Q100 Grade 1 qualification, VIO-based logic voltage flexibility, and integrated battery-short protection-making it the sole choice for safety-critical, mixed-supply automotive CAN nodes.

FAQ

What is the function of the VIO pin on the TLE8250GVIOXUMA5?

The VIO pin supplies the digital I/O interface voltage (3.0–5.5 V) for TxD, RxD, and NEN pins. It sets logic thresholds to match the microcontroller's I/O voltage-enabling direct connection to either 3.3 V or 5 V MCUs without external level shifters. Internal circuitry references all digital inputs/outputs to VIO, not VCC.

How does the TLE8250GVIOXUMA5 handle bus short-circuits?

The TLE8250GVIOXUMA5 provides built-in protection against CANH/CANL shorts to ground, battery, or VCC. During a short, current limiting engages to prevent damage, and the device maintains functional isolation-ensuring unaffected nodes continue communicating. This behavior is validated per ISO 11898-2 Annex C test conditions.

What happens when the NEN pin is left floating?

The NEN pin has an internal pull-up to VIO, so a floating NEN defaults to logic High, placing the device in Stand-By mode. In this state, both driver and receiver are disabled, CANH/CANL enter high-impedance, and quiescent current drops to ~15 µA-ideal for low-power sleep states while preserving bus integrity.

Is the TLE8250GVIOXUMA5 compatible with CAN FD networks?

The TLE8250GVIOXUMA5 is a classical HS-CAN transceiver compliant with ISO 11898-2 (up to 1 MBit/s) and does not support CAN FD's variable bit rates or enhanced arbitration. It operates transparently in CAN FD networks only at nominal 1 MBit/s data phase-but lacks FD-specific timing or error-handling enhancements required for full FD compliance.
