Product details
Overview
IFX1050GVIOXUMA1 from Infineon Technologies is a high-speed CAN transceiver IC compliant with ISO/DIS 11898, serving as the physical layer interface between a CAN protocol controller and differential bus lines (CANH/CANL) in industrial 12 V and 24 V systems. It supports up to 1 MBaud data rate, features logic I/O voltage adaptability (3.3 V–5 V via V33V pin), integrated overtemperature protection, and short-circuit robustness on bus pins.
For engineers reviewing the IFX1050GVIOXUMA1 datasheet, IFX1050GVIOXUMA1 pinout, IFX1050GVIOXUMA1 application, or IFX1050GVIOXUMA1 equivalent, key selection considerations include differential receiver threshold (0.75–0.90 V recessive-to-dominant), bus common-mode range (−20 V to +25 V), standby current (≤10 μA), logic supply flexibility, and PG-DSO-8 package compatibility with industrial PCB layouts.
Technical Context
The IFX1050GVIOXUMA1 implements a fully differential bus driver and receiver with hysteresis (150 mV) to ensure noise-immune dominant/recessive state detection. Its dual-supply architecture separates VCC (5 V bus-side supply) from V33V (3.3 V–5 V logic-side supply), enabling direct interfacing with mixed-voltage microcontrollers without level shifters.
Thermal shutdown activates at 160–200 °C junction temperature with 10 °C hysteresis, and the inhibit (INH) pin provides hardware-controlled entry into low-power standby mode (<10 μA ICC+33V,stb), making it suitable for energy-sensitive industrial nodes requiring wake-on-CAN capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Data Rate | 1 MBaud - supports full-speed CAN FD physical layer signaling in legacy CAN networks |
| Differential Threshold (Vdiff,d) | 0.75–0.90 V - ensures reliable recessive-to-dominant transition detection under EMI stress |
| Common-Mode Range | −20 V to +25 V - enables operation in electrically noisy industrial environments with ground offsets |
| Standby Current | ≤10 μA - allows battery-backed or low-power remote nodes to maintain bus presence with minimal leakage |
| Logic Supply Range (V33V) | 3.0–5.5 V - eliminates external level translators when interfacing with 3.3 V or 5 V MCUs |
| Thermal Shutdown | 160–200 °C with 10 °C hysteresis - prevents latch-up during sustained bus fault conditions |
| Bus Pin Protection | Short-circuit proof to GND and battery - sustains continuous connection to 24 V rail or chassis ground without damage |
Pinout & Package
IFX1050GVIOXUMA1 is housed in a PG-DSO-8 (SOIC-8) surface-mount package with exposed thermal pad, RoHS-compliant, and rated for industrial temperature range (−40 °C to +125 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TxD | CAN transmit data input | 20 kΩ internal pull-up; driven LOW by MCU to assert dominant state on bus |
| GND | Ground reference | Common return for VCC, V33V, and bus receiver; must be low-impedance for EMC stability |
| VCC | 5 V bus-side supply | Powers driver stage and bus termination circuitry; decoupling capacitor required near pin |
| RxD | CAN receive data output | Open-drain output with internal pull-up; LOW = dominant, HIGH = recessive |
| V33V | Logic supply input | Sets voltage level for TxD, RxD, and INH I/O thresholds; accepts 3.3 V or 5 V directly |
| CANL | Low-side bus line | Differential bus terminal; short-circuit tolerant to GND and battery voltage |
| CANH | High-side bus line | Differential bus terminal; short-circuit tolerant to GND and battery voltage |
| INH | Inhibit control input | 20 kΩ internal pull-up; driven LOW to enable normal mode, HIGH for standby |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive Logic I/O Voltage | V33V pin auto-scales TxD/RxD/INH thresholds across 3.3 V–5 V, removing need for external level-shifting circuitry |
| Differential Receiver Hysteresis | 150 mV built-in hysteresis prevents chatter during slow-rising/falling bus edges in noisy environments |
| Bus Fault Tolerance | CANH/CANL withstand −40 V to +40 V absolute max, including direct short to 24 V battery or chassis ground |
| EMC-Optimized Driver | Controlled slew rate and symmetrical drive strength minimize radiated emissions while maintaining 1 MBaud timing integrity |
| Thermal Protection | Integrated junction temperature sensor triggers shutdown at 160–200 °C with automatic recovery after cooldown |
Applications
| Industrial PLC Node | Automotive Body Control Module |

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/3/1 | Single 5 V supply (no V33V pin); fixed 5 V logic I/O; lower common-mode range (−12 V to +12 V) | Requires external level shifter for 3.3 V MCUs; less suited for ground-noisy industrial sites | Select if system uses only 5 V microcontrollers and operates within automotive-grade EMI limits |
| MCP2551-I/P | Legacy 5 V-only design; no standby mode; no thermal shutdown; higher ESD sensitivity (±2 kV HBM) | Lacks power management and fault protection needed for unattended industrial deployments | Choose only for cost-sensitive, non-safety-critical legacy designs with stable 5 V supplies |
Compared with TJA1042T/3/1 and MCP2551-I/P, IFX1050GVIOXUMA1 uniquely combines adaptive logic voltage, industrial-grade common-mode tolerance, and hardware-enabled ultra-low-power standby-making it optimal for mixed-voltage, thermally demanding, or energy-constrained industrial CAN nodes.

FAQ
What logic voltage levels does IFX1050GVIOXUMA1 support on its digital I/O pins?
The IFX1050GVIOXUMA1 adapts its TxD, RxD, and INH logic thresholds to the voltage applied to the V33V pin, which accepts 3.0 V to 5.5 V. This eliminates external level shifters when interfacing with either 3.3 V or 5 V microcontrollers, and internal voltage comparators scale thresholds proportionally (e.g., VTD,H = 0.55 × V33V).
How does the INH pin control operational modes?
The INH pin is an active-low enable input with a 20 kΩ internal pull-up. Driving INH LOW places the device in Normal Mode (full bus activity); leaving it HIGH (or floating, due to pull-up) forces Standby Mode, reducing total supply current to ≤10 μA while retaining bus wake-up capability via CANH/CANL edge detection.
Is IFX1050GVIOXUMA1 compatible with ISO 11898-2:2016?
Yes - the IFX1050GVIOXUMA1 meets the electrical requirements of ISO/DIS 11898 (2003 edition), which forms the basis of ISO 11898-2:2016. Its differential threshold (0.75–0.90 V), common-mode range (−20 V to +25 V), and bus fault protection align with the standard's physical layer specifications for high-speed CAN.
Does IFX1050GVIOXUMA1 require external bus termination resistors?
No - the IFX1050GVIOXUMA1 does not integrate bus termination. A standard 120 Ω resistor must be placed externally across CANH and CANL at each bus end per ISO 11898-2. The transceiver's differential input resistance (20–60 kΩ) and output drive strength are designed to operate correctly with this external termination.
