Infineon Technologies TLE7250GVIOXUMA2

Overview

TLE7250GVIOXUMA2 from Infineon Technologies is a high-speed CAN transceiver compliant with ISO 11898-2, serving as the physical-layer interface between a CAN protocol controller and the differential bus. It supports data rates up to 1 Mbps, features VIO voltage adaptation for 3.3 V or 5 V microcontrollers, includes TxD time-out and overtemperature protection, and operates in normal, stand-by, and power-down modes for automotive network resilience.

For engineers reviewing the TLE7250GVIOXUMA2 datasheet, TLE7250GVIOXUMA2 pinout, TLE7250GVIOXUMA2 application, or TLE7250GVIOXUMA2 equivalent, key selection criteria include CAN bus leakage current in power-down state (≤1 µA), common-mode range (−2 V to 14 V), ESD immunity per IEC61000-4-2 (±8 kV contact), fail-safe TxD time-out, and AEC-Q100 qualification for automotive deployment.

Technical Context

The TLE7250GVIOXUMA2 implements a fully differential HS-CAN physical layer with matched slew-rate control on CANH/CANL to minimize electromagnetic emission (EME) while maintaining ISO 11898-2-compliant dominant/recessive voltage thresholds (VDIFF ≥ 1.5 V dominant, ≤ 0.5 V recessive). Its Smart Power Technology (SPT) integrates bipolar/CMOS logic with DMOS drivers for robust transient immunity.

Mode control is managed via the NEN (Not Enable) pin, enabling deterministic transitions between normal-operating mode (NEN = low, transmitter/receiver active), stand-by mode (NEN = high, both disabled), and undervoltage-triggered power-down. The VIO supply independently sets logic-level compatibility, decoupled from VCC, allowing mixed-voltage system integration without level shifters.

FAQ

Is the TLE7250GVIOXUMA2 pin-compatible with the TLE6250GV33?

Yes, the TLE7250GVIOXUMA2 is fully pin-compatible with the TLE6250GV33, including identical pin assignment and electrical behavior. Pin 8 was renamed from INH to NEN, but the function remains unchanged - active-low enable with internal VIO-referenced pull-up. No PCB redesign is required for migration.

What is the purpose of the VIO pin, and can it be tied to VCC?

The VIO pin supplies the logic interface circuitry and sets the voltage threshold for TxD, RxD, and NEN pins. It may be tied to VCC only if the microcontroller operates at the same voltage (e.g., both at 5 V); otherwise, it must be connected to the MCU's I/O supply (e.g., 3.3 V) to ensure correct logic-level translation and avoid damage or misoperation.

Does the TLE7250GVIOXUMA2 support wake-up from CAN bus activity?

No, the TLE7250GVIOXUMA2 does not support bus wake-up. It lacks a dedicated WAKE pin or local wake-up detection circuitry. It operates in normal, stand-by, and power-down modes controlled solely by the NEN pin and VCC/VIO supply conditions - wake-up must be handled externally by the MCU or system controller.

How does the TxD time-out function behave during CAN arbitration?

The TxD time-out triggers after ~1.2 ms of continuous dominant TxD assertion, forcing the transmitter into recessive state regardless of MCU output. During arbitration, this prevents a stuck-at-dominant fault from blocking the bus, allowing other nodes to regain control - a critical fail-safe for multi-node automotive networks where arbitration resolution must remain deterministic.
