Infineon Technologies TLE8250VSJXUMA1

Overview

TLE8250VSJXUMA1 from Infineon is a high-speed CAN transceiver compliant with ISO 11898-2:2003, serving as the physical-layer interface between CAN controllers and automotive HS CAN buses. It supports CAN FD data rates up to 2 MBit/s, features VIO voltage adaptation for microcontroller compatibility, operates across extended supply ranges (VCC: 4.5–27 V, VIO: 2.7–5.5 V), and delivers <255 ns loop delay symmetry for deterministic timing in engine control and chassis modules.

For engineers reviewing the TLE8250VSJXUMA1 datasheet, TLE8250VSJXUMA1 pinout, TLE8250VSJXUMA1 application, or TLE8250VSJXUMA1 equivalent, key selection criteria include guaranteed CAN FD timing compliance, dual-supply operation (VCC/VIO), fail-safe TxD time-out, power-save mode with VCC shutoff capability, and AEC-Q100 qualification for automotive deployment.

Technical Context

The TLE8250VSJXUMA1 implements a differential HS CAN physical layer with matched transmitter slew rates on CANH/CANL to minimize EME and ensure <255 ns loop delay symmetry-critical for reliable CAN FD arbitration at 2 MBit/s. Its dual-supply architecture isolates digital logic (VIO) from bus driver (VCC), enabling independent power management.

Two operational modes are controlled via the NEN pin: normal mode activates both transmitter and receiver with dominant/recessive thresholds of VDiff ≥1.5 V (dominant) and ≥0.9 V / ≤0.5 V (receiver), while power-save mode disables both, sets RxD high, and allows VCC shutdown-reducing quiescent current to <10 µA with <1 µA bus leakage.

Key Specifications

Pinout & Package

Supplied in PG-DSO-8 package (RoHS-compliant, lead-free, exposed thermal pad), the TLE8250VSJXUMA1 uses an 8-pin SOIC footprint with integrated heat sink pad connected to GND for thermal stability under continuous bus fault conditions.

FAQ

What is the maximum CAN FD data rate supported by the TLE8250VSJXUMA1?

The TLE8250VSJXUMA1 supports CAN FD data rates up to 2 MBit/s, verified through loop delay symmetry ≤255 ns and compliance with ISO 11898-2:2003 timing requirements. This performance is validated for Japanese OEM applications and meets VeLIO interoperability test specifications for dominant/recessive signal transitions.

How does the VIO pin function in relation to microcontroller voltage levels?

The VIO pin supplies the digital logic section and sets the voltage thresholds for TxD input and RxD output, enabling direct interfacing with 2.7–5.5 V microcontrollers-including 3.3 V and 5 V MCUs-without external level shifters. VIO remains powered during power-save mode to maintain wake-up readiness.

Does the TLE8250VSJXUMA1 include built-in protection against bus faults?

Yes, the TLE8250VSJXUMA1 provides CANH/CANL short-circuit protection to battery, ground, and VCC, plus overtemperature shutdown at 175 °C. It also features ±8 kV HBM ESD protection and −27 V to +40 V common-mode transient immunity-eliminating need for external protection components in most automotive layouts.

Can the TLE8250VSJXUMA1 operate with VCC disconnected while retaining functionality?

No-VCC must be present for transmitter operation in normal mode. However, in power-save mode, VCC may be safely turned off while VIO remains active; the device then enters low-power state with RxD held high and CANH/CANL in high-impedance, drawing <10 µA total supply current.
