Product details
Overview
TLE9250XSJXUMA1 from Infineon is a high-speed CAN transceiver compliant with ISO 11898-2 (2016) and SAE J2284-4/-5, serving as the physical layer interface between microcontrollers and HS CAN bus in automotive ECUs. It supports CAN FD data frames up to 5 MBit/s, features VIO voltage adaptation (3.3 V / 5 V), ±8 kV HBM ESD robustness, and operates across VCC = 4.5–5.5 V and VIO = 3.0–5.5 V.
For engineers reviewing the TLE9250XSJXUMA1 datasheet, TLE9250XSJXUMA1 pinout, TLE9250XSJXUMA1 application, or TLE9250XSJXUMA1 equivalent, key selection criteria include loop delay symmetry for CAN FD timing integrity, fail-safe TxD time-out and overtemperature protection, common-mode immunity (±35 V), and PG-DSO-8 package compatibility with automated optical inspection requirements.
Technical Context
The TLE9250XSJXUMA1 implements a fully differential HS CAN transceiver architecture with independent transmitter and receiver paths, enabling precise loop delay symmetry (tLOOP(H,L) ≈ tLOOP(L,H)) critical for CAN FD bit-rate stability up to 5 MBit/s. Its internal mode control logic interprets RM pin state to select Normal, Forced-Receive-Only, or Receive-Only operation.
It integrates VIO-supplied logic-level translation for MCU interface compatibility, dual-supply decoupling (VCC and VIO each require 100 nF to GND), and failsafe functions including thermal shutdown at 170–190 °C, short-circuit protection on CANH/CANL, and TxD time-out limiting dominant bus states to ≤ 1.5 ms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CAN Bit Rate | Up to 5 MBit/s - enables CAN FD high-speed data phase without external timing compensation. |
| VIO Supply Range | 3.0–5.5 V - allows direct interfacing with 3.3 V or 5 V microcontrollers without level-shifting circuitry. |
| ESD Robustness | ±8 kV HBM on CANH/CANL - eliminates need for external TVS diodes in most automotive harness environments. |
| Common-Mode Range | ±35 V - ensures reliable operation under severe automotive load-dump and coupling transients per ISO 7637. |
| Bus Leakage Current (Power-down) | < 1 µA - minimizes quiescent current draw when disabled, supporting low-power vehicle wake-up architectures. |
| Thermal Shutdown Threshold | 170–190 °C - protects against latch-up during sustained overcurrent or ambient overheating in engine bay mounting. |
| Loop Delay Symmetry | < 50 ns mismatch - guarantees deterministic signal edge alignment essential for CAN FD error-free sampling at 5 MBit/s. |
Pinout & Package
Package: PG-DSO-8 (RoHS-compliant, halogen-free, leaded SOIC variant with exposed thermal pad).
| 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 | Primary analog/digital return path; connects to PCB ground plane and thermal pad. |
| 3 VCC | Transmitter Supply | 4.5–5.5 V supply for CAN driver stage; requires 100 nF decoupling capacitor to GND. |
| 4 RxD | Receive Data Output | CMOS output referenced to VIO; "low" indicates dominant bus state, open-drain compatible. |
| 5 VIO | Digital Interface Supply | 3.0–5.5 V supply setting logic thresholds for TxD/RxD; requires 100 nF decoupling capacitor to GND. |
| 6 CANL | CAN Bus Low I/O | Differential bus terminal; driven low during dominant state; withstands ±40 V DC fault conditions. |
| 7 CANH | CAN Bus High I/O | Differential bus terminal; driven high during dominant state; withstands ±40 V DC fault conditions. |
| 8 RM | Receive-Only Mode Control | Active-low input with internal pull-down; "low" enables normal operation, "high" forces receive-only mode. |
Key Features
| Feature | Design Value |
|---|---|
| VIO-adapted logic interface | Enables seamless integration with both 3.3 V and 5 V microcontrollers without external level shifters. |
| Guaranteed loop delay symmetry | Ensures <50 ns skew between CANH/CANL edges, meeting CAN FD timing margin requirements at 5 MBit/s. |
| TxD time-out function | Automatically disables transmitter after ≤1.5 ms dominant state, preventing bus lockup due to MCU firmware faults. |
| Overtemperature protection | Thermal shutdown activates at 170–190 °C with 5–20 K hysteresis, allowing safe recovery after transient overload. |
| Short-circuit proof bus pins | CANH/CANL survive direct shorts to battery, ground, VCC, or VIO without damage or latch-up. |

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 |
|---|---|---|---|
| NXP TJA1044T/3 | Lower ESD rating (±6 kV HBM), no VIO pin - fixed 5 V logic interface only. | Limited to 5 V MCU systems; less robust in high-ESD manufacturing or service environments. | Select when cost sensitivity outweighs need for dual-voltage interface and enhanced ESD margin. |
| ST TSN485EDR | Supports only classical CAN (1 MBit/s max); lacks CAN FD timing symmetry and TxD time-out. | Suitable for legacy powertrain networks but not for new CAN FD-based ADAS or chassis domains. | Choose only for backward-compatible upgrades where 5 MBit/s and fail-safe timeout are not required. |
Compared with TJA1044T/3 and TSN485EDR, the TLE9250XSJXUMA1 uniquely combines VIO flexibility, 5 MBit/s CAN FD readiness, and integrated fail-safes-making it optimal for next-generation automotive domain controllers requiring functional safety and electromagnetic resilience.
