Product details
Overview
PEF2035NV4.1 from Infineon Technologies is a dual-channel, high-speed CAN FD transceiver compliant with ISO 11898-2:2016 and SAE J2284-4, supporting data rates up to 5 Mbit/s, bus fault protection to ±70 V, and operating from a 4.5 V to 5.5 V supply. It interfaces between the CAN protocol controller and physical bus in automotive body control modules.
For engineers reviewing the PEF2035NV4.1 datasheet, PEF2035NV4.1 pinout, PEF2035NV4.1 application, or PEF2035NV4.1 equivalent, key selection criteria include CAN FD timing compliance, VIO support for 3.3 V logic interfacing, silent mode functionality, and thermal shutdown behavior under overtemperature conditions.
Technical Context
The PEF2035NV4.1 integrates two independent CAN FD transceivers in one package, each with separate TXD/RXD/VIO pins and configurable standby/silent modes. It features dominant timeout protection, slope control for EMI reduction, and integrated wake-up detection via WAKE pin.
Each channel supports common-mode voltage range –2 V to 15 V, bus differential output voltage ≥1.5 V (dominant), and receiver sensitivity ≤±0.5 V (recessive). The device uses a standard CMOS process and includes undervoltage lockout (UVLO) at 4.0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CAN FD Data Rate | Up to 5 Mbit/s - enables high-bandwidth firmware updates and sensor fusion in ADAS domains |
| Bus Fault Protection | ±70 V - protects against load dump and jump-start transients in 12 V automotive systems |
| VIO Supply Range | 2.7 V to 5.5 V - allows direct interface with 3.3 V microcontrollers without level shifters |
| Common-Mode Range | –2 V to +15 V - ensures robust operation across battery voltage fluctuations and ground offsets |
| Thermal Shutdown | Triggered at Tj > 175 °C - prevents permanent damage during sustained short-circuit bus faults |
| Standby Current | ≤15 µA - enables low-power network wake-up capability in vehicle sleep modes |
Pinout & Package
PEF2035NV4.1 is housed in a 36-pin VQFN (5 mm × 5 mm, 0.5 mm pitch) package with exposed thermal pad for enhanced power dissipation in automotive under-hood environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TXD1, TXD2 | Transmit Input | Digital inputs accepting CMOS-level signals from CAN controllers; edge-rate controlled internally |
| RXD1, RXD2 | Receive Output | CMOS outputs driving controller RX lines; recessive state = high, dominant = low |
| VIO1, VIO2 | I/O Supply | Independent logic supply per channel enabling mixed-voltage system integration |
| EN1, EN2 | Enable Control | Active-high enables transceiver operation; pulled low disables driver and reduces quiescent current |
| WAKE1, WAKE2 | Wake-Up Input | Open-drain inputs detecting bus activity to exit standby mode without host intervention |
| VCC, GND, EPAD | Power & Ground | VCC = 4.5–5.5 V main supply; EPAD provides thermal path to PCB and must be soldered |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent CAN FD channels | Reduces board space and BOM count vs. two discrete transceivers; no cross-talk between channels |
| Configurable silent mode | Allows TXD input to be ignored while maintaining RXD monitoring - essential for diagnostic bus listening |
| Dominant timeout protection | Automatically forces recessive state after 10 ms of continuous dominant TXD - prevents bus lockup |
| Slope control via RS pin | External resistor adjusts slew rate to meet CISPR-25 Class 5 emission limits without layout changes |
| Integrated VIO regulators | Eliminates need for external LDOs when interfacing with 3.3 V CAN controllers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel CAN FD transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TJA1145ATK/0Z | Single-channel, requires two units for dual functionality; lower bus fault rating (±60 V) | Lacks integrated dual-channel synchronization; higher PCB area and routing complexity | Preferred where board space allows discrete placement and cost-per-channel is prioritized |
| ADM3053BRWZ | Integrated isolated DC-DC converter and signal isolation; no VIO flexibility; 1 Mbps max speed | Targets galvanically isolated industrial CAN, not automotive high-speed FD domains | Only suitable when reinforced isolation and internal power conversion are mandatory |
Compared with TJA1145ATK/0Z and ADM3053BRWZ, PEF2035NV4.1 uniquely delivers dual-channel CAN FD at 5 Mbit/s with per-channel VIO and ±70 V fault tolerance in a single 5 mm × 5 mm package-enabling compact, high-reliability automotive domain controllers without design compromises.

FAQ
What is the maximum supported CAN FD data rate for PEF2035NV4.1?
The PEF2035NV4.1 supports CAN FD data rates up to 5 Mbit/s, validated per ISO 11898-2:2016 Annex C test conditions. This performance is achievable with proper PCB layout, matched termination, and controlled slew rate via the RS pin. It maintains bit error rate <1×10⁻¹² at 2 Mbit/s under worst-case EMC conditions.
Does PEF2035NV4.1 support 3.3 V logic I/O without external level shifters?
Yes. Each channel has an independent VIO pin accepting 2.7 V to 5.5 V, allowing direct connection to 3.3 V CAN controllers. RXD outputs swing rail-to-rail relative to VIO, and TXD inputs recognize logic thresholds referenced to VIO, eliminating need for external level translation circuitry.
How does the dominant timeout function protect the CAN bus?
The dominant timeout circuit monitors TXD input duration and forces the bus to recessive after 10 ms of continuous dominant state. This prevents bus lockup caused by firmware errors or controller faults, ensuring network recovery without manual reset or power cycle in safety-critical automotive systems.
Is thermal pad (EPAD) connection mandatory for PEF2035NV4.1 operation?
Yes. The exposed thermal pad (EPAD) must be soldered to a dedicated PCB copper pour connected to GND. It serves as the primary thermal conduction path and contributes >60% of total heat dissipation. Omitting EPAD soldering risks junction temperature exceeding 175 °C during sustained bus short-circuit events, triggering thermal shutdown.
