Product details
Overview
IFX1054GXUMA1 from Infineon Technologies is a fault-tolerant low-speed CAN transceiver designed for industrial bus interfaces, supporting data rates up to 125 kBaud, operating from 5 V (VCC) and battery-supply (VS) rails, with integrated bus failure management and single-wire fallback mode for CANH or CANL line faults. It enables robust communication in harsh environments such as factory automation controllers and distributed I/O modules.
For engineers reviewing the IFX1054GXUMA1 datasheet, IFX1054GXUMA1 pinout, IFX1054GXUMA1 application, or IFX1054GXUMA1 equivalent, key selection criteria include its dual-edge wake-up capability, VS supply fail flag, thermal protection, differential-to-single-wire mode transition logic, and INH-controlled external voltage regulator interface.
Technical Context
The IFX1054GXUMA1 implements a three-mode operation architecture-Normal, Receive-Only, and Sleep-with mode selection via NSTB and ENT digital inputs and automatic state transitions governed by timeout thresholds (e.g., th(min)). Its failure management unit monitors CANH/CANL differential voltage and bus line shorts/open circuits to trigger RTL/RTH-controlled termination resistor activation and single-wire transmission.
Wake-up is supported via dual-edge-sensitive WK input or bus activity detection, with RxD and NERR outputs used to signal wake events and battery failure states respectively; the device maintains functional integrity during VS undervoltage or VCC loss by transitioning to VBAT Stand-By mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 125 kBaud - supports low-speed CAN networks compliant with ISO 11898-3. |
| Supply Voltages | VCC = 5 V ±10 %; VS = 5–27 V - enables direct battery connection and ECU-level power domain separation. |
| Bus Fault Tolerance | Detects and recovers from CANH/CANL short-to-battery, short-to-ground, open-circuit, and cross-wire faults - ensures continued node presence in degraded bus conditions. |
| Wake-Up Sensitivity | Dual-edge on WK pin; also responds to dominant bus transitions - eliminates need for external edge-detection circuitry. |
| Thermal Protection | Integrated thermal shutdown - prevents latch-up or permanent damage during sustained overtemperature operation. |
| EMC Performance | Symmetric slew-rate control on CANH/CANL - allows use of unshielded twisted-pair cabling without violating CISPR 25 Class 3 radiated emission limits. |
Pinout & Package
IFX1054GXUMA1 is housed in a PG-DSO-14 (14-pin exposed pad SOIC) package with moisture sensitivity level MSL3 and RoHS-compliant finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 INH | Inhibit output | Open-drain signal to disable external 5 V regulator in Sleep mode - reduces system standby current. |
| 2 TxD | Transmit data input | CMOS-compatible input with internal pull-up; LOW drives dominant bus state, HIGH enables recessive state. |
| 3 RxD | Receive data output | CMOS output with internal pull-up; reflects bus state (LOW = dominant, HIGH = recessive) and signals wake-up in low-power modes. |
| 4 NERR | Error flag output | Indicates bus error in Normal mode; repurposed as VS fail flag in Receive-Only mode. |
| 5 NSTB | Not stand-by input | Digital control pin (active-high) that, with ENT, selects Normal, Receive-Only, or Sleep mode per state diagram. |
| 6 ENT | Enable transfer input | Digital control pin (active-high) used with NSTB to define operational mode and initiate Go-to-Sleep transition. |
| 7 WK | Wake-up input | Dual-edge sensitive input; triggers wake-up on rising or falling edge - no external debouncing required. |
| 8 RTH | Termination resistor output (H-side) | Drives external 500 Ω–16 kΩ resistor to CANH during bus failure - enables single-wire mode with CANL only. |
| 9 RTL | Termination resistor output (L-side) | Drives external 500 Ω–16 kΩ resistor to CANL during bus failure or Sleep mode - provides pull-up to battery voltage. |
| 10 VCC | Logic supply input | 5 V ±10 % supply for internal logic and drivers; requires local ceramic decoupling. |
| 11 CANH | High-side CAN bus line | Differential bus terminal; driven HIGH in dominant state, floats in recessive state. |
| 12 CANL | Low-side CAN bus line | Differential bus terminal; driven LOW in dominant state, floats in recessive state. |
| 13 GND | Ground reference | Analog/digital common return; must be connected directly to PCB ground plane with low-inductance path. |
| 14 VS | Battery supply input | Wide-range input (5–27 V) for monitoring battery health and enabling VBAT Stand-By mode during VCC loss. |
Key Features
| Feature | Design Value |
|---|---|
| Fault-tolerant single-wire fallback | Automatically switches to RTL/RTH-driven single-wire mode upon CANH or CANL line failure - preserves node visibility and diagnostic access. |
| Dual-edge wake-up detection | WK pin responds to both rising and falling edges - eliminates missed wake events in noisy industrial environments. |
| VS supply fail flag | NERR output indicates VS undervoltage in Receive-Only mode - enables early battery health warning without microcontroller polling. |
| INH-controlled regulator disable | INH goes high-impedance in Sleep mode to shut down external 5 V regulator - cuts system quiescent current to sub-100 µA. |
| Thermal shutdown protection | Internal sensor disables drivers above safe junction temperature - prevents thermal runaway during overload or poor heatsinking. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TJA1055T/3 | Higher minimum operating voltage (VS ≥ 6 V); no INH output; fixed 5 V VCC only | Lacks regulator control and VS fail flag - unsuitable for battery-fail diagnostics or ultra-low-power sleep sequencing | Select when system uses dedicated 5 V regulator and does not require battery monitoring or deep-sleep coordination. |

FAQ
What is the purpose of the INH pin on IFX1054GXUMA1?
The INH (Inhibit) pin is an open-drain output used to control an external 5 V voltage regulator. In Sleep mode, INH goes high-impedance to disable the regulator, reducing system standby current. During wake-up, it transitions to active-low to re-enable the regulator once VCC is stable - enabling precise power sequencing between transceiver and microcontroller.
How does IFX1054GXUMA1 handle CAN bus line failures?
Upon detecting CANH or CANL line faults (e.g., short-to-battery, open-circuit), the IFX1054GXUMA1 activates internal RTH or RTL outputs to connect external termination resistors, switching to single-wire communication mode. This preserves node presence on the bus and allows continued reception of messages - critical for diagnostics and safety monitoring in industrial networks.
Can IFX1054GXUMA1 operate with only VS supply and no VCC?
No. VCC (5 V) is mandatory for internal logic and driver operation. However, if VCC is lost while VS remains present, the device enters VBAT Stand-By mode - maintaining WK and bus activity wake-up capability and signaling the condition via NERR. Full functionality resumes only after VCC is restored and mode pins are asserted.
What is the function of the NERR pin in Receive-Only mode?
In Receive-Only mode, NERR is repurposed as a VS supply fail flag: it outputs LOW when VS drops below the undervoltage threshold (typically ~4.5 V). This provides immediate battery health feedback to the microcontroller without requiring ADC sampling or polling - enabling fast low-battery response in portable or remote industrial nodes.
